A bettor in Aotearoa New Zealand who looks for a place to put a wager on rugby, the Black Caps or the Melbourne Cup is shopping in a market that has one lawful shop. Since the Racing Industry Amendment Act 2025 inserted section 74AAA into the Racing Industry Act 2020, in force from 28 June 2025, only TAB NZ may offer racing and sports betting to a person in New Zealand. The online arm sits under two brands: TAB and Betcha. Offshore bookmakers taking bets from New Zealand residents are breaking the same section, and the Department of Internal Affairs told providers to withdraw with immediate effect. That is the legal frame this whole page sits inside, and every figure, every margin and every wagered dollar below requires reading against it.

This article was checked against the New Zealand register on October 30, 2026 and against the DIA’s public position on the betting prohibition. The monopoly position is the one the regulator is publicly enforcing; offer details, fees and wagering terms are quoted from each operator’s own terms as they stood at that check.

The shortlist: who actually takes your money in New Zealand

The premise of a “top ten” for New Zealand falls apart the moment the law is read. A ranking of licensed bookmakers, the kind a sports betting comparison usually prints, is in this country a ranking of one: TAB NZ, operating through TAB and Betcha. The other brands a New Zealand punter meets — Thunderpick, BigClash, Telbet, RTbet, 22Bet, Roobet, Spinbara, Alawin — are bookmakers that may have plenty of customers elsewhere, none of them with a licence that reaches a person in New Zealand. Treating them as rivals to TAB NZ on a comparison page quietly launders them into the lawful market. They sit here as the alternatives a New Zealander will hear about and consider, and each row says plainly that they are not licensed in New Zealand.

Two of those rows are the same operator group: TAB and Betcha are the two online brands of TAB NZ, run under a 25-year partnership Entain signed in 2023 that gives Entain a 50/50 share of gross profits, with at least NZ$150 million a year going to TAB NZ for the first five years, plus a one-off NZ$100 million payment Entain pledged to the racing sector. That partnership is a deal about who runs the monopoly, not a deal that opens it. The wagering market in New Zealand is a single counterparty, and the rest of this page is what that single counterparty — and the illegal alternatives a punter will still meet — cost the person on the other side of the bet slip.

What a wager on New Zealand sport actually is, and what sits inside it

A bet is a contract that pays a return if the chosen outcome happens, and nothing if it does not. The mechanics are the same wherever the bookmaker sits, and the monopoly does not change them. What the monopoly changes is who the counterparty is and what protections sit on top.

The Racing Industry Act 2020 defines the kinds of wager TAB NZ may offer. Fixed-odds bets pay a price agreed at the time the bet is placed; tote (or pool) bets pay a dividend set after the race closes, with the pool divided among winning tickets minus a take-out. Racing bets on TAB NZ come in well-known types: Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Daily Double, Running Double, Quaddie and Big6. Sports bets are organised as Multis — combinations of legs that pay only if every leg wins — and Same Game Multis, where the legs all come from one event. Live betting is listed in the TAB NZ apps. What is not established is whether any statutory restriction on in-play markets applies, and no New Zealand betting exchange exists, so an instruction like “lay the All Blacks” is not available from any lawful counterparty in this country.

A “Same Game Multi” is the form that has come to dominate single-event wagering. The punter picks several outcomes from one match — the All Blacks to win, the total points to be over a line, a particular try-scorer to cross — and the book prices them as one combined ticket. The legs multiply into a single price, which is what the punter sees on the slip. The price looks generous because the inputs do; the price is generous because the legs are correlated and the book is repricing them, and the cost of that single ticket is paid through the bookmaker’s margin sitting inside each leg, on top of the extra premium a Same Game Multi adds for the correlation itself. It is the form most likely to turn “a small wager” into a “ticket that needs every leg to land” without the punter noticing the difference.

The wager itself is the easy part. The cost is the part the slip does not show, and it is what the rest of this page pulls apart.

How the law shapes what a New Zealand punter can actually bet on

The Racing Industry Act 2020 makes TAB NZ the only lawful provider of racing and sports betting to a person in New Zealand, regardless of where that bookmaker or that punter is incorporated or resident (Racing Industry Amendment Act 2025, in force 28 June 2025). The Department of Internal Affairs is the regulator; it monitors compliance with the betting prohibition under section 92A of the same Act. There is no licence to apply for, no licence register for bookmakers, and the only body to register a complaint with on a betting dispute is the operator’s own dispute process and, ultimately, the courts.

What may be bet on is racing and sports, through TAB NZ. The Racing Industry Act’s list of racing codes includes thoroughbred, harness and greyhound racing. Greyhound racing is closing in stages from 1 August 2026, and from that date offshore operators may not take bets on greyhound races either. The list of sports is whatever TAB NZ chooses to price in its programme; in the current apps that includes rugby union and rugby league (All Blacks, Super Rugby Pacific, NRL), cricket (Black Caps), football, tennis, basketball, NFL, NBA, MMA/UFC and motorsports. What is not established is whether the law treats esports as a “sport” for the betting monopoly, so a punter looking for a CS2 line in a New Zealand-context article is asking a question the law has not yet settled. The 2026 online casino law, separately, treats virtual (computer-simulated) sport as casino gambling, which is a different licence and a different regime.

Bets on politics and novelty markets are not established. No statutory per-bet cap exists; limits are TAB NZ’s own house rules. The law does not geo-block offshore websites; it puts liability on the offshore operator that knowingly takes the bet. The point-of-consumption charge that the government had been collecting on offshore racing and sports bets ceased on 30 June 2026, removing one of the tax handles that had been used to police the cross-border market without changing the underlying prohibition.

For the punter, section 19(4) of the Gambling Act 2003 (inserted in 2025) says an individual may not be convicted for placing a bet with an offshore operator in breach of section 74AAA. No published penalty for a player was found. The right line is that the law targets the operator, and the regulator’s stated risks to a player using an offshore bookmaker are real but not criminal: unspent credits may not be returned, large wins may not be paid, and the New Zealand harm-minimisation framework does not reach the account.

The price on the slip, and what sits inside it

Every price a bookmaker publishes already contains the bookmaker’s margin. The punter sees odds like 1.90 and 1.90 on a two-way market — for example, the All Blacks at 1.90, the opposition at 1.90 — and reads them as a fair toss-up. They are not. The payout share of a market is the share of every dollar wagered that the book returns across all outcomes if those prices held; the margin is the slice the book keeps.

Take a two-way market priced at 1.90 / 1.90 as an example. The payout share is 1 ÷ (1/1.90 + 1/1.90) = 1 ÷ (0.5263 + 0.5263) = 1 ÷ 1.0526 ≈ 0.9500, or about 95.00%. The margin is 1 − 0.9500 = 0.0500, or 5.00%. For every NZ$100 wagered across the market, about NZ$95 comes back in winnings and the book keeps about NZ$5 — whether the All Blacks win or lose. The headline number on the slip does not change; the cost of the bet is paid in the price.

The honest picture: a 5% margin is a useful benchmark and a generous one for the punter. Rugby league and rugby union pre-match margins in mature markets typically sit between 5% and 8%. Horse racing margins on tote are lower because the take-out is published separately, but fixed-odds racing on a card priced for a soft Saturday tends to sit in the same band. The larger the bookmaker’s margin, the less of every wagered dollar the field of punters gets back, and the more of every wagered dollar the book keeps regardless of who wins. The punter does not pay the margin as a fee. The punter pays the margin as a built-in tax on every ticket.

Two ways the margin shows up that a punter is more likely to feel than to read about. First, on a Same Game Multi, the leg prices look generous and the multi price looks very generous; the correlation premium and the per-leg margin are both in the headline number, and the slip does not separate them. Second, in-play prices move quickly, and a price that was 1.90 at half-time can be 1.65 within a minute of a try. The price drop is real, but the margin in the new price is not lower than the margin in the old one; the new price carries a bookmaker’s reaction to a smaller liability window, and the margin rides on top. The cost of the bet does not shrink with the price; it simply moves to a different shape.

The cost of a “free” or “boosted” offer, and the rules that come with it

The wagering market outside TAB NZ runs on sign-up offers — “100% match”, “free bet”, “boosted odds”, “risk-free”. The word to read carefully in any of them is the one in front. A “free bet” is a token whose stake is not returned with a win: the punter keeps the winnings above the stake, not the stake itself. A “risk-free” bet is, on close reading, a refund of the stake as a free bet when the first bet loses, not a refund in money. A “boosted odds” offer raises the headline price on one outcome but usually caps the stake that gets the boost, and a cap on free-bet winnings is common. None of these are illegal; none of them are what the marketing says they are.

The arithmetic the slip does not show is the wagering requirement. A 100% deposit match typically carries a wagering factor — the multiple of the bonus that has to be turned over in qualifying bets before any winnings become withdrawable. A factor of 5x on a NZ$100 bonus means NZ$500 of qualifying turnover before the bonus balance converts. A turnover of NZ$500 at an average margin of 5% on the markets the bookmaker counts as qualifying costs the punter about NZ$25 in expected margin — a quarter of the bonus — before the bonus money is even reached. A factor of 10x doubles that. A minimum price rule typically disqualifies bets at odds below 1.50, which is most pre-match favourites in major codes; a deadline typically runs 7, 14 or 30 days. Each rule is a place a margin can be paid by the punter without the punter noticing the line item.

A punter in New Zealand who opens an account with an offshore bookmaker to claim a sign-up offer is also accepting that the operator’s own dispute process, the operator’s own terms and the operator’s own home regulator — usually Curaçao — are the only routes for a complaint. The Department of Internal Affairs’ stated warnings are that an offshore bookmaker may not return unspent credits, may not pay out large wins and operates in a jurisdiction with minimal consumer safeguards. A sign-up offer is a way for the book to acquire a customer; the wagering terms are the cost the book is happy to wear only because the margin inside the qualifying turnover will, on average, pay for it.

The verdict on the offer is the one the marketing is designed to avoid. A free bet is worth the bookmaker’s payout share of the market at the price the punter takes. A boosted-odds offer is worth the difference between the boosted price and the unboosted price, capped at the stake the offer allows, multiplied by the chance the boosted leg lands. A risk-free bet is worth roughly the free-bet value of the refund, which is the same free bet with a smaller stake. None of these are what the headline says. Each of them is a price, and the price is the one the slip will not print.

Picking from the wagering menu: which sport, which market, which form

A punter in New Zealand picking what to bet on has a different decision than a punter in a market with twenty rivals. The market depth, the in-play range and the breadth of niche codes are not what they are offshore. TAB NZ’s programme is the programme, and the programme is what the punter has.

The major codes a New Zealand punter is most likely to want — rugby union (All Blacks, Super Rugby Pacific), rugby league (NRL), cricket (Black Caps, white-ball formats, IPL, BBL), football (A-League, English Premier League, Champions League, FIFA internationals), basketball (NBA, NBL), NFL, tennis (the four slams, ATP, WTA) — are all priced pre-match and in-play. The Melbourne Cup and the major Australian races are priced in the racing product, with the racing types set out earlier. Motorsports, MMA/UFC, and a small set of niche sports round out the menu. Where the menu is thin, the punter is the one who pays for it: a market with one lawful price is a market with no comparable price to check it against, and the margin inside that single price is whatever the market-maker chose to charge.

A practical order to a Saturday card. Start with the market the punter actually knows — most punters do better on the code they watch than the code they read about. Restrict the ticket to outcomes where the price genuinely reflects a difference of view; a market at 1.10 on a hot favourite is not a market, it is a fee, and the margin inside it is the entire cost of the bet for a near-zero return. Same Game Multis look generous on the slip because the headline price is large, and they are a poor choice for the same reason: the correlation premium and the per-leg margin compound. A single bet at a fair price on a market the punter has an opinion on is the lowest-cost wager available; a multi at an inflated price on correlated legs is the highest. The market a punter thinks they are choosing and the market a punter is choosing are usually not the same.

The practical exception is the same race. On a Quaddie or Big6, the punter is choosing between wide and narrow combinations: the wide combination costs more and pays less per dollar if it lands, the narrow combination costs less and pays more but at a much lower chance. Either form is a bet the same way any other is — a margin rides inside each leg — and the punter pays that margin either way. The Quaddie is a wagering product, not a way to outflank the maths.

Walking through a wager, from account to payout

For a TAB NZ account, the practical order is straightforward. The account is opened in the TAB or Betcha app, the New Zealand address is verified, the age is confirmed (18+; betting under 18 is an offence under section 89 of the Racing Industry Act 2020), and a deposit method is set. The wallet is the same wallet in both apps because the apps are two front doors on the same TAB NZ account. A deposit can be a card, a bank transfer, or a POLi-style instant bank payment; specific methods and limits are operator-level and come from TAB NZ’s own terms, not from a statute.

From the wallet, the punter picks a market — a race, a match, an in-play line — and adds a selection to the bet slip. The slip shows the price (decimal, in the New Zealand form, like $2.10 for a 2.10 decimal), the stake and the potential return. The punter places the bet. For racing, the bet is either a fixed-odds bet or a tote bet, and the bet type is set at placement: Win, Place, Each Way, Quinella, Exacta, Trifecta, First Four, Double, Treble, Quaddie, Big6, or a Multi. For sports, the bet is a single, a Multi or a Same Game Multi. In-play betting is available in the app on the markets TAB NZ prices live.

Settlement is the part the punter rarely watches for. A fixed-odds sports bet settles when the market is settled by TAB NZ’s feed; a Same Game Multi settles when the last leg is decided; a tote bet settles when the pool is finalised and the dividend is published. A refund on a void leg, on a scratcher in a race, on an abandoned match or on a market that did not produce a result, is paid at the bookmaker’s own terms — TAB NZ publishes a set of rules for what happens in each case. The payout goes back to the same wallet, and withdrawals are subject to TAB NZ’s verification and payment-method rules. A self-exclusion set in the app covers both brands, because the brands are one account.

The bet is not complicated. What is complicated is the layer of terms the punter is agreeing to at placement: minimum price rules, maximum stake rules, maximum free-bet winnings, maximum payout per market, and the cut-off times for placing a bet before a race or a match. Each term is a place the bookmaker can refuse a bet, void a bet or cap a payout. The punter pays for these terms in the prices the book publishes, and the prices already include the margin.

The harm-minimisation framework TAB NZ sits inside, and what offshore does not

TAB NZ accounts have safer-gambling tools built into the app: deposit limits, time-outs and self-exclusion. A self-exclusion set on a TAB NZ account is honoured across the TAB and Betcha brands, which is a real consumer protection because it works across the two front doors of the same account. The age is 18 for betting, and the app carries a 17+ App Store age rating while stating 18+ for betting. Land-based casino gambling in New Zealand is 20; that is a different regime and a different age, and the two are not interchangeable.

The free Gambling Helpline (0800 654 655, text 8006) and Safer Gambling Aotearoa are the public-sector help routes. TAB NZ contributes to harm minimisation through a Problem Gambling Levy of 0.74% (in force from 1 July 2025 to 30 June 2028). None of this is the punter’s expense; it is the framework the operator sits inside, and it is the framework a New Zealand-resident offshore account does not sit inside. The Department of Internal Affairs warns that overseas operators may be in jurisdictions with minimal consumer safeguards, may not return unspent credits and may not pay out large wins. A New Zealand harm-minimisation framework that does not reach the account is a framework the punter is paying the cost of the absence of.

What offshore does offer is a wider programme: more in-play markets on smaller leagues, more exotic bet types, more niche codes, and crypto deposit methods. The wider programme is the lure, and the absence of a New Zealand complaints route is the price. There is no published penalty for a New Zealand punter using an offshore bookmaker (the law targets the operator), and the punter is not a criminal. The punter is a customer of a counterparty the New Zealand regulator cannot discipline and the New Zealand harm-minimisation framework cannot reach, and the slip on an offshore account does not print that line either.

The calculation: how much a margin on a market actually costs the punter

The arithmetic in the headline number is straightforward, and the result is the whole point. Take the same example from earlier: a two-way market at 1.90 and 1.90, the kind of line a punter sees on most weekends. The payout share is 1 ÷ (1/1.90 + 1/1.90) = 0.9500, or 95.00%. The margin is 5.00%. Read that as: for every NZ$100 the field of punters wagers across the market, NZ$95 comes back in winning tickets and the book keeps NZ$5, regardless of who wins the match.

The band, with its condition, is the right way to state the result. For a balanced two-way line near 1.90, the margin sits around 5% as a rule of thumb; a line at 1.85 / 1.85 is wider, around 8%; a line at 1.95 / 1.95 is tighter, around 2.5%. Tighter markets are not common in New Zealand rugby, cricket or football pre-match, and the punter who wants the tightest margin will price-shop across bookmakers — which in New Zealand means looking at both TAB NZ brands and, if the punter is willing to take the offshore route, the offshore bookmakers on the same event, while accepting the section 74AAA risk that comes with the offshore account. The honest version of “shop the price” in New Zealand is “place a TAB NZ bet, accept the margin, and don’t open an offshore account for a sign-up offer”.

That last point is the one the marketing around sign-up offers is designed to obscure. A 100% deposit match that carries a 5x wagering factor on the bonus, a 1.50 minimum price on qualifying bets, and a 30-day deadline is an offer the punter pays for in the margin inside the qualifying turnover: NZ$500 of qualifying turnover at a 5% margin costs about NZ$25 in expected margin, before the bonus money is even reached. A factor of 10x doubles that cost. A free bet is worth the payout share of the market at the price the punter takes, not the headline stake; a “free NZ$50” is rarely worth NZ$50 once the wagering and the cap on free-bet winnings are read. The arithmetic is the part the marketing does not show, and the arithmetic is the cost of the offer.

The wagering product compared, brand by brand

The brands below are listed in a fixed order. TAB and Betcha are the two online brands of TAB NZ; the rest are bookmakers a New Zealand punter will meet and that, as of the check on October 30, 2026, are not licensed in New Zealand. Each entry is a description and a judgement; none is a recommendation to sign up, deposit or bet.

TAB

TAB is the original brand of TAB NZ, with a retail network of TAB outlets and the tab.co.nz online operation. The app carries horse and harness racing, rugby union and rugby league and other sports, pre-match and live, and is published in the New Zealand App Store under the seller name New Zealand Racing Board. The app was first released on 8 September 2014 and carries a 17+ App Store age rating while stating 18+ for betting.

The wagering product covers the racing types set out in the Racing Industry Act 2020 — Win, Place, Each Way, Quinella, Exacta, Trifecta, First4, Double, Treble, Daily Double, Running Double, Quaddie, Big6 — and a sports product of singles, Multis and Same Game Multis. Trackside live race streaming is built into the app with in-app betting; racing form, Blackbook and Jockey Challenge tools are listed; the wallet is a simplified deposit and withdrawal flow. The safer-gambling tools (deposit limits, time-outs, self-exclusion) sit in the app, and the Gambling Helpline (0800 654 655, text 8006) is published in the app listing.

The verdict. For a New Zealand punter who wants a wager on a Black Caps ODI or a Melbourne Cup field under a New Zealand harm-minimisation framework, with a regulator that can discipline the operator and a dispute process that sits inside the domestic courts, TAB is the only lawful counterparty. The price the punter pays is the price the only counterparty publishes, and the margin inside that price is whatever the market-maker charges. That is the trade.

Betcha

Betcha is the second online brand of TAB NZ, published on the New Zealand App Store by Entain New Zealand Limited and first released on 6 August 2024. The two brands are not rivals; they are two front doors on the same TAB NZ account, run by Entain under the partnership set out earlier in this page.

The wagering product is the same product, with a presentation aimed at a younger, sports-first punter. The sports menu covers rugby, NRL, MMA/UFC, NBA, NFL, tennis, cricket, football, motorsports and esports, and the racing menu covers horse, greyhound and harness racing. Same Game Multis are central to the product. The wallet is shared with TAB; a self-exclusion on one brand is honoured on the other.

The verdict. For a punter who prefers placing a wager through a sports-first app rather than a racing-led product, Betcha is the same TAB NZ wager with a different front door. The cost of the wager is the same cost, and the harm-minimisation framework is the same framework. The punter who already has a TAB account does not need a Betcha account to use the product; the punter who only knows Betcha is still placing the bet with TAB NZ, and the law treats it the same way.

Thunderpick

Thunderpick is an esports-first bookmaker covering CS2, League of Legends, Dota 2 and Valorant, with a sportsbook that includes a cash-out feature and markets from the Champions League to the NFL. The brand names a Curaçao licence (OGL/2024/677/0722), holder Paloma Media B.V., which gives no right to take bets from a person in New Zealand.

For a New Zealand punter, the wagering offer is a broader esports menu than TAB NZ’s programme, with a crypto-fluent wallet and a sportsbook on top. The cost is what the section 74AAA prohibition costs: the account is not reachable by the New Zealand harm-minimisation framework, the dispute process is the operator’s own process under Curaçao law, and the Department of Internal Affairs’ stated warnings about unspent credits, large wins and consumer safeguards apply.

The verdict. For a New Zealand punter who wants a CS2 line or a League of Legends market that TAB NZ does not price, the choice is the broader programme and the absence of the New Zealand framework, against the law that makes the choice unlawful for the operator. The product is what it is; the legal position is what it is; the punter is the one who pays the cost either way.

BigClash

BigClash runs pre-match and live sports betting across international and local leagues, with virtual sports and esports on FPS and MOBA titles. The brand names a Curaçao licence (8048/JAZ), which gives no right to take bets from a person in New Zealand.

The wagering offer is similar in shape to the other offshore brands on this list: a sportsbook on top of a casino, virtual sports and esports, with promotions tied to the casino side of the business. The wider programme is the draw. The narrower regulatory reach is the cost.

The verdict. For a punter who wants virtual sports and an FPS line in the same wallet as a Premier League match, BigClash is an offshore option. The New Zealand section 74AAA position remains identical to the rest of the offshore list, and the punter pays for the wider programme in the absence of the domestic framework. The product is what it is.

Telbet

Telbet describes itself as a crypto casino and sportsbook, with a welcome offer of 200% up to 1 BTC plus 50 free spins and a 5 USDT free bet on its Russian-language site. The English site shows a sportsbook with in-play betting, a My Bets page, and published sports betting, bonus, responsible-gambling and AML policies. The brand names no licence that applies in New Zealand.

The wagering offer is a crypto-fluent bookmaker with separate published policies on the sports side, which is a step better than a brand that hides its sports terms inside a casino T&Cs page. The wagering and bonus terms are still where the cost sits, and the cost is the same cost any 200% match carries: a wagering factor, a minimum price, a deadline, a cap on free-bet winnings.

The verdict. For a punter who wants a separate sports betting rule set and a crypto wallet, Telbet is one of the offshore books that publishes the rules a reader can read. The section 74AAA position is the same as the rest of the offshore list, and the punter pays for the offer in the qualifying turnover.

RTbet

RTbet’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with live betting and virtual sports. The brand names a Curaçao licence, which gives no right to take bets from a person in New Zealand.

The wagering offer is a broad mainstream sportsbook on top of a casino, with a programme of live betting that runs from the major leagues to the smaller ones. The cost is the same cost the section 74AAA prohibition costs any offshore brand.

The verdict. For a punter who wants a US-sports-heavy bookmaker on top of football, RTbet is an offshore alternative. The domestic framework does not reach the account, and the punter pays the cost of that absence.

22Bet

22Bet’s sportsbook offers over 30 market types per event, including 1X2, Double Chance, totals, both teams to score, correct score and HT-FT, plus tennis game, set and handicap markets. The brand names a Curaçao licence (8048/JAZ), holder TechSolutions Group N.V., which gives no right to take bets from a person in New Zealand.

The wagering offer is the deepest market-type menu on the offshore list, and the deep menu is the draw. A market-type menu of 30+ on a single football match is a way to find a market the margin is thinner on, and a way to find a market the punter has less view on; the menu does not change the section 74AAA position.

The verdict. For a punter who wants 30+ market types on a Champions League group match, 22Bet is an offshore alternative. The cost is the same cost the rest of the offshore list carries.

Roobet

Roobet’s sportsbook covers soccer, basketball, tennis, Counter-Strike, FIFA, baseball, ice hockey, MMA and table tennis, and its terms require players to be 18 or older. The brand names a Curaçao licence (OGL/2024/687/0427), holder Raw Entertainment B.V., which gives no right to take bets from a person in New Zealand.

The wagering offer is a sportsbook on top of a crypto-led casino, with a programme that runs across the major codes. The cost is the same cost the rest of the offshore list carries.

The verdict. For a punter who wants a crypto-fluent bookmaker with a mainstream sports menu, Roobet is an offshore alternative. The domestic framework does not reach the account.

Spinbara

Spinbara advertises a first deposit bonus of 100% up to EUR 100 and a sport crypto welcome bonus of 100% up to 200 USDT on its English site, alongside a casino welcome bonus of 100% up to EUR 500 plus 200 free spins. The brand names no licence that applies in New Zealand.

The wagering offer is a casino-led brand with a sportsbook on top, and the welcome bonuses are the draw. A 100% match up to EUR 100 is the same shape of offer any offshore book runs: a bonus, a wagering factor, a minimum price, a deadline, a cap on free-bet winnings. The section 74AAA position is the same as the rest of the offshore list.

The verdict. For a punter who wants the welcome bonus and is willing to do the turnover, Spinbara is one of the offshore books that runs it. The cost of the bonus is the margin inside the qualifying turnover, and the cost of the account is the absence of the New Zealand framework.

Alawin

Alawin’s sportsbook covers football, tennis, table tennis, basketball, ice hockey, American football and baseball, with Live Betting, Virtual Sports and esports also offered. The brand names no licence that applies in New Zealand.

The wagering offer is a mainstream offshore sportsbook on top of a casino, with a programme of live betting and virtual sports. The cost is the same cost the rest of the offshore list carries.

The verdict. For a punter who wants a US-sports and football menu with virtual sports and esports in the same wallet, Alawin is an offshore alternative. The domestic framework does not reach the account.

What “cost” actually means, in three numbers a punter can hold

Three figures, each with a condition, are the practical takeaway from this page.

The first is the margin. For a balanced two-way line near 1.90 / 1.90, the margin is about 5% as a rule of thumb; the actual figure on any given market depends on the prices the book publishes. The cost is paid by the field of punters across every ticket, in the price, regardless of who wins.

The second is the qualifying turnover. A 100% deposit match with a 5x wagering factor on a NZ$100 bonus means NZ$500 of qualifying turnover before the bonus converts; a 10x factor means NZ$1,000. The cost of the turnover, at a 5% margin, is about NZ$25 or NZ$50 in expected margin respectively — a quarter to a half of the bonus — before the bonus is reached. The condition is that only bets at or above the minimum price count, and the deadline runs 7, 14 or 30 days.

The third is the free-bet value. A NZ$50 free bet at 2.10 with a market payout share of 0.95 is worth NZ$50 × (2.10 − 1) ÷ 2.10 × 0.95 = NZ$50 × 0.5238 × 0.95 ≈ NZ$24.88 in expected value. The condition is that the stake is not returned with a win, the price is the price the punter takes, and the payout share is the share of the market the book publishes. The “free” in “free bet” is not the headline stake.

Each figure is an estimate, not a guarantee. The bet pays what it pays, the bonus converts when it converts, the free bet wins when it wins. The arithmetic tells a punter what the wager is worth on average, and the average is what the punter pays.

Frequently asked questions

How is the return on a bet worked out from the stake and the odds?

For a single bet, the return is stake multiplied by the decimal odds, and the net profit above the stake is stake multiplied by (odds minus 1). A NZ$10 bet at 2.10 returns NZ$21 and pays NZ$11 in profit; a NZ$10 bet at 1.50 returns NZ$15 and pays NZ$5. For a combination bet, the odds of the legs multiply into a single price, and the stake is multiplied by that combined price to give the return. The return is what a winning bet pays back; it is not the chance the bet wins. A 2.10 single pays NZ$21 on a NZ$10 stake when it wins, and pays nothing when it does not.

How do the odds reflect the bookmaker’s margin?

For a market with all outcomes priced, the payout share is one divided by the sum of the reciprocals of the decimal odds, and the margin is one minus the payout share. A two-way market at 1.90 and 1.90 has a payout share of about 0.9500 and a margin of about 0.0500, or 5.00%. The book keeps about 5% of every dollar wagered across the market, regardless of which outcome wins. The margin is the cost of the bet, paid in the price, on every ticket. A punter who wants the tightest margin price-shops across bookmakers; in New Zealand that means the two TAB NZ brands against each other, since offshore alternatives break section 74AAA.

Which bookmaker may lawfully take sports and racing bets in New Zealand?

TAB NZ, through its two online brands TAB and Betcha, is the only provider lawfully offering racing and sports betting to a person in New Zealand since 28 June 2025, when section 74AAA of the Racing Industry Act 2020 took effect. The Department of Internal Affairs told providers serving New Zealand to withdraw with immediate effect. There is no licensing route for another bookmaker and no licence register for betting, because there is only one lawful operator. An offshore bookmaker taking a wager from a person in New Zealand is breaking New Zealand law; the law targets the operator, and the punter is not criminalised, but the New Zealand harm-minimisation framework and complaints route do not reach an offshore account.

How is a Same Game Multi priced, and what does the punter actually pay?

A Same Game Multi combines several outcomes from one event into one ticket, and the legs multiply into a single price. The punter sees a large headline number and pays a per-leg margin on each leg plus an extra premium for the correlation between the legs. The premium is the book’s charge for repricing correlated outcomes; the per-leg margin is the cost the punter pays on each leg as a single bet. The punter pays both, in the headline price. A Same Game Multi at a 4.00 headline price is rarely worth four times a 2.00 single; it is worth the multiplicative price of the legs minus the correlation premium, and the correlation premium is whatever the book charges. The cheapest wager on one event is a single bet at a fair price, not a multi at an inflated one.

How does a punter price-shop on the same event across the two TAB NZ brands?

A price-shop on the same event across TAB and Betcha is a price-shop on the same bookmaker, because the brands share a TAB NZ account and a wallet. A genuine price-shop in New Zealand means watching the line move on the one operator, and placing the bet when the price is the price the punter wants. A punter who wants a counter-shop on a tighter margin will not find a second lawful counterparty in New Zealand. That is the trade the monopoly sets, and it is the trade this page has been pulling apart section by section.
