Short answer: Rooster Bet is the best all-round online betting site for New Zealanders — tightest measured margins on Super Rugby and NPC, a genuine NZD wallet, and a three-hour median withdrawal. Bet&Play is the choice for in-play. Gunsbet has the largest welcome offer in the New Zealand-facing market at roughly NZ$13,900, with the slowest cashier to match.
Most betting pages rank on bonus size, which is the least important variable in the whole exercise. A NZ$500 welcome offer is worth NZ$500 once. Betting into a 106% market instead of a 102.5% market costs a punter turning over NZ$500 a week roughly NZ$900 a year, every year. This page leads with the margins.
Measured margins by code
The overround is the sum of implied probabilities across a market. 100% is a fair book; everything above is the operator’s edge. These figures are the median of a weekly sample taken across the 2026 season to date.
| Market | Best offshore | TAB NZ | Offshore median | Worst offshore | Tightest book |
|---|---|---|---|---|---|
| Super Rugby Pacific, head to head | 102.4% | 104.1% | 103.2% | 105.8% | Rooster Bet |
| Bunnings NPC, head to head | 102.9% | 104.6% | 103.8% | 106.2% | Rooster Bet |
| All Blacks test, head to head | 101.8% | 103.2% | 102.4% | 104.9% | Bet&Play |
| NRL, head to head | 102.6% | 104.0% | 103.1% | 105.4% | Bet&Play |
| A-League, 1X2 | 104.2% | 106.1% | 105.0% | 107.8% | Rooster Bet |
| ANZ Premiership, match winner | 104.8% | — | 105.6% | 108.2% | Ivibet |
| Black Caps ODI, head to head | 102.2% | 103.6% | 102.8% | 105.1% | Rooster Bet |
| NZ thoroughbred, win market | 116.5% | 118.0% | 117.2% | 122.4% | Rooster Bet |
One caveat we will state plainly: a tight margin is worth nothing if the book restricts you for winning. Offshore operators do limit accounts, and the books with the sharpest prices tend to be the quickest to do it. We have not been limited at any operator on this page, but our stakes are small and our sample is not a substitute for your own experience.
Is online betting legal in New Zealand?
Yes, for the person placing the bet. The position has three parts and they are commonly confused.
- You may bet offshore. No New Zealand law makes it an offence for a resident to place a bet with an overseas bookmaker, and none is proposed.
- Only TAB NZ may offer betting from within New Zealand. The Racing Industry Act 2020 gives TAB NZ that exclusivity, and its commercial operations have been run in partnership with Entain since 2023.
- Offshore operators pay to take New Zealand bets. The Act introduced offshore betting charges — a consumption charge and a betting information use charge — payable by overseas bookmakers taking bets from New Zealand residents. That is an obligation on them, not on you.
TAB NZ versus offshore bookmakers
This is the real decision for most New Zealand punters, and both answers are defensible.
| TAB NZ | Offshore books | |
|---|---|---|
| Legal status | New Zealand licensed and regulated | Legal for you to use; not NZ-licensed |
| Margin, mainstream rugby | 103–104% | 102–103% |
| Margin, NZ racing | Tote pools plus fixed odds | 116–122% fixed odds, fewer exotics |
| NZ racing depth | Complete — every meeting, every exotic | Main meetings, win/place/each-way |
| Welcome offers | Limited by NZ rules | NZ$200 to NZ$13,900 |
| In-play | Restricted on some codes | Full in-play on main codes |
| Withdrawal speed | 1–2 business days to a NZ bank | 3 hours on crypto, 1–5 days on card |
| Currency | NZD always | NZD at 7 of 12 books here |
| Dispute resolution | NZ regulator and Disputes Tribunal | Offshore regulator only |
| Funds NZ racing and sport | Yes, directly | Via offshore betting charges only |
| Account restrictions for winning | Less aggressive | Varies; sharper books restrict sooner |
The honest summary: TAB NZ is the better product for New Zealand racing and the better protected place to hold money, and it funds the codes you are betting on. Offshore books are sharper on mainstream sport, faster to pay, and offer bonuses TAB cannot. Plenty of regular punters keep a TAB account for racing and one or two offshore accounts for sport, and shop for the price on the day. That is a reasonable position.
The sports New Zealanders bet on
Rugby union
Super Rugby Pacific, the Bunnings NPC, All Blacks tests, the Rugby Championship and Farah Palmer Cup. The deepest market lists of any code here, with player props and multi-leg builders at the better books.
Rugby league
NRL including the Warriors, State of Origin and international tests. Consistently well priced offshore because of Australian liquidity.
Cricket
Black Caps across all formats, the Super Smash, Plunket Shield, plus the IPL and international tournaments. In-play is strong on internationals, thin on domestic.
Netball
ANZ Premiership and Silver Ferns tests. Genuinely under-served offshore — Ivibet is the book that prices it properly.
Ivibet Sportsbook →Football
A-League with Auckland FC and the Wellington Phoenix, the All Whites, plus the full European programme. Widest market counts of any sport.
Racing
New Zealand thoroughbred and harness, Australian meetings, the Melbourne Cup carnival, UK and Irish racing.
NZ racing detail →Basketball
NBA, NBL including the Breakers, and the Tall Blacks. Deep in-play and player props on NBA.
Esports
CS2, League of Legends, Dota 2 and Valorant. Growing quickly and priced loosely at several books, which cuts both ways.
Everything else
Golf including New Zealand players on tour, tennis, UFC, motorsport, the America’s Cup and politics markets at some books.
New Zealand racing
Racing is where TAB NZ and offshore books are most clearly different products, and where New Zealand had the biggest structural change of 2026.
Greyhound racing has ended
Commercial greyhound racing in New Zealand ceased on 1 August 2026. The Racing Industry (Closure of Greyhound Racing Industry) Amendment passed its third reading 112 votes to 11 following a twenty-month wind-down announced in December 2024, after independent reviews in 2013, 2017 and 2021 found persistent animal welfare problems. Australian, British and Irish greyhound meetings are still available at offshore books and through TAB NZ; New Zealand dogs are not.
Thoroughbred and harness
Both continue and both are well covered domestically. New Zealand thoroughbred racing centres on the Ellerslie, Trentham, Riccarton and Te Rapa programmes, with the New Zealand Derby and the Karaka Millions as the marquee days. Harness racing runs year-round with Addington and Alexandra Park as the principal tracks and the New Zealand Trotting Cup in November as the highlight.
| TAB NZ | Offshore books | |
|---|---|---|
| Meetings covered | Every NZ meeting | Main metropolitan meetings; patchy midweek |
| Bet types | Win, place, each-way, quinella, trifecta, first four, Pick 6 | Win, place, each-way; limited exotics |
| Pricing model | Tote pools and fixed odds | Fixed odds only |
| Typical win-market overround | Tote — varies with pool | 116–122% |
| Best-tote or SP options | Yes | Rare |
| Australian coverage | Comprehensive | Comprehensive, often better priced |
For New Zealand racing specifically, TAB NZ is the better product and it is not close. Offshore books are worth an account for Australian meetings and for the occasional fixed-odds price that beats the tote, not as a replacement.
In-play and live betting
In-play is where a sportsbook’s trading quality is exposed. A weak book suspends constantly, re-prices slowly and voids bets it does not like. We tested every book on this page through a full Super Rugby Pacific round and an NPC Saturday.
| Book | In-play codes | Suspension behaviour | Cash-out | Bet slip on mobile |
|---|---|---|---|---|
| Bet&Play | Rugby, league, cricket, football, tennis, basketball | Minimal — no unexplained suspensions in our test | Yes, partial | Best in class |
| Rooster Bet | Rugby, league, cricket, football, netball, basketball | Occasional, always explained | Yes, partial | Very good |
| Kingdom | Rugby, league, football, basketball, tennis | Occasional | Yes | Good |
| Rivo | Rugby, league, football, basketball | Occasional | Yes | Fastest to load |
| Gunsbet | Football, tennis, basketball, rugby | Frequent on rugby | Yes | Good |
| Ivibet | Football, basketball, cricket | Frequent | Limited | Basic |
Deposits, withdrawals and NZD
The same rails as the casino side, with the same two rules: hold your balance in New Zealand dollars if you can, and withdraw on the rail you deposited with.
| Book | NZD wallet | NZD bank transfer | Crypto | Min deposit | Weekly cap | Median payout |
|---|---|---|---|---|---|---|
| Rooster Bet | Yes | Yes | BTC, ETH, USDT | NZ$25 | NZ$8,000 | 3h 00m |
| Kingdom | Yes | Yes | BTC, ETH, USDT, DOGE | NZ$20 | NZ$10,000 | 2h 50m |
| Smash | Yes | Yes | BTC, ETH, USDT, DOGE | NZ$20 | NZ$10,000 | 4h 30m |
| Bet&Play | Yes | Yes | BTC, ETH, USDT | NZ$20 | NZ$7,000 | 6h |
| MadCasino | Yes | Yes | BTC, ETH, USDT | NZ$20 | NZ$8,000 | 8h |
| Rivo | Yes | Yes | BTC, ETH, USDT | NZ$25 | NZ$8,000 | 5h 15m |
| Lucky Vibe | Yes | Yes | BTC, USDT | NZ$25 | NZ$6,500 | 13h |
| Ivibet Sportsbook | No | No | BTC, ETH, USDT | NZ$20 | NZ$5,000 | 16h |
| Gunsbet | No — EUR | No | None | NZ$35 | €4,000 | 18h |
| Spino | No — crypto only | No | 8 coins | 20 USDT | None published | 38 min |
Note the trade-off at the top of the bonus table: Gunsbet offers the largest welcome in the market and is the only book here with no crypto, no NZD and a €4,000 weekly cap. If you win big there, extracting it is a project. More on payment methods.
Bet types explained
| Bet type | What it is | When it makes sense | Watch out for |
|---|---|---|---|
| Head to head / moneyline | Pick the winner | The default. Tightest margins, cleanest maths. | Draw handling differs by sport — check whether it is a three-way market |
| Handicap / line | One side starts with a points advantage | Mismatched teams, where the head-to-head price is unbettable | Half-point lines exist to eliminate the push; whole numbers can be refunded |
| Totals / over-under | Combined points above or below a line | When you have a view on tempo rather than outcome | Weather moves rugby and cricket totals hard |
| Each way | Half the stake on the win, half on a place | Racing, and golf outrights | Place terms vary by field size and by book — read them before the stake goes on |
| Multi / accumulator | Several selections, all must win | Rarely. The margin compounds with every leg. | A four-leg multi at 104% per leg is a 117% book against you |
| Bet builder | Multiple markets within one match | When correlated outcomes are priced as if independent | The correlation is usually priced in; the margin is higher than a straight multi |
| In-play | Betting after the start | When you are watching live, not streaming | Latency, suspensions and re-pricing on acceptance |
| Futures / outrights | Season-long markets | Early value before a market matures | Your money is tied up for months; dead-heat and non-runner rules matter |
Free bets and what they are worth
A free bet returns the winnings but not the stake, so a NZ$100 free bet at even money pays NZ$100, not NZ$200. Its real value is roughly 70–80% of face, and lower once you apply the turnover requirement.
| Book | Sports welcome | Turnover | Minimum odds | Real cost to clear |
|---|---|---|---|---|
| Gunsbet | 285% up to €7,500 | 40x bonus | — | Very high — effectively decorative |
| Smash | 250% up to NZ$9,800 | 15x | — | Workable on a large deposit |
| Kingdom | 200% up to NZ$1,900 | Per terms | — | Moderate |
| Bet&Play | 100% up to NZ$500 | 5x at 1.80+ | 1.80 | Low — genuinely clearable |
| Ivibet Sportsbook | 100% up to NZ$200 | 5x at 2.00+ | 2.00 | Low |
| Rooster Bet | 100% up to NZ$350 free bet | 6x | — | Moderate — NZ$2,100 turnover |
| Fortune Play | 100% up to NZ$350 free bet | 6x | — | Moderate |
| MadCasino | 100% up to NZ$400 | Per terms | — | Moderate |
| Rivo | 100% up to NZ$300 | Per terms | — | Moderate |
| Lucky Vibe | 100% up to NZ$250 | Per terms | — | Moderate |
Betting on a phone
Every book here is browser-based; none has an app in the New Zealand App Store, because Apple and Google both restrict real-money gambling apps here. What you get instead is a responsive site you can add to a home screen.
Three things separate a good mobile book from a bad one, and only one of them is speed. The bet slip must stay docked when you scroll, it must show a price change before it accepts the bet rather than after, and it must survive a rotation without losing your selections. Bet&Play is the only book here that does all three reliably. Rivo is the fastest to load on a poor connection.
Betting responsibly
Sports betting feels like a skill game, which makes it easier to justify chasing a loss than a pokie does. The protections are the same and they are worth using before you need them.
- Set a deposit limit on day one. Every book here supports daily, weekly and monthly limits in account settings.
- Never bet a market you would not have bet before the loss. Chasing shows up as unfamiliar sports at odd hours — that is the pattern to watch for in yourself.
- Keep a record of every bet. Most people who believe they are ahead are not, and a spreadsheet settles it in a fortnight.
- Ask your bank for a gambling block if you need a harder stop. ANZ, ASB, BNZ, Kiwibank and Westpac all offer them.
- Free, confidential help: Gambling Helpline 0800 654 655, 24 hours, or free text 8006.

Online betting NZ — frequently asked questions
Is online betting legal in New Zealand?
Yes, for you. New Zealand law prohibits anyone other than TAB NZ from offering sports and racing betting from within New Zealand — that is the effect of the Racing Industry Act 2020 — but it has never been an offence for a New Zealander to place a bet with an overseas bookmaker. Offshore operators taking bets from New Zealand are also subject to offshore betting charges under that Act. Note that the Online Casino Gambling Act 2026 covers online casino gambling only; sports betting is a separate regime and TAB NZ’s domestic exclusivity is unchanged.
Is TAB NZ better than an offshore bookmaker?
Better at some things, worse at others. TAB NZ is New Zealand-based, regulated here, funds the domestic racing and sporting codes, and offers genuine local depth on New Zealand racing. Offshore books are typically sharper on price — our weekly sample puts the better offshore books 1.5 to 3 percentage points tighter on overround for mainstream rugby and football markets — and they offer welcome bonuses TAB cannot match. Many New Zealand punters hold both and shop for the price.
Do I pay tax on betting winnings in New Zealand?
Not as a recreational punter. Inland Revenue does not treat casual gambling winnings as income. The exception is a person betting as a business — systematically, with an expectation of profit and the organisation to match — which is rare and worth professional advice if you think it describes you.
What is an overround, and why does it matter more than the odds?
The overround is the bookmaker’s built-in margin. Convert every price in a market to an implied probability and add them up: a fair market totals 100%, and anything above that is the book’s edge. A rugby head-to-head at 102.5% is a much better market than one at 106%, even if the favourite’s price looks similar. We publish measured overrounds on this page because it is the only honest way to compare bookmakers.
Can I bet on the NPC and Super Rugby with offshore bookmakers?
Yes, and coverage is good. Every book on this page prices Super Rugby Pacific and the Bunnings NPC head-to-head, handicap and totals markets, and most offer in-play. Depth varies: Rooster Bet and Bet&Play carry player props and multi-leg builders on NPC matches, while smaller books offer head-to-head only.
Can I still bet on greyhound racing in New Zealand?
Not on New Zealand greyhounds. Commercial greyhound racing in New Zealand ended on 1 August 2026 under the Racing Industry (Closure of Greyhound Racing Industry) Amendment, which passed 112 votes to 11. Australian, British and Irish greyhound meetings are still available at most offshore books and through TAB NZ. New Zealand thoroughbred and harness racing are unaffected.
What is the fastest way to get a betting withdrawal in New Zealand?
Cryptocurrency, by a wide margin — a median of about three hours against one to five business days on a card. Among the books here, Kingdom (2h 50m median) and Rooster Bet (3h) are the fastest with a fiat option; Spino is faster still at 38 minutes but is crypto-only. Gunsbet, which has the biggest welcome offer, has no crypto at all and takes 12–24 hours at best.
Do offshore bookmakers offer in-play betting on New Zealand sport?
The better ones do. Bet&Play has the sharpest in-play engine we tested and stayed live through a full Super Rugby Pacific round and an NPC Saturday without unexplained suspensions. Rooster Bet and Kingdom also offer in-play on the main New Zealand codes. Be aware that all offshore in-play runs a few seconds behind a live broadcast, and further behind a delayed stream.
What happens to a bet if a match is abandoned?
It depends on the book’s rules and the sport, and this is worth reading before you need it. The common position for rugby and football is that bets are void and stakes returned if a match is abandoned before a defined point, and stand if abandoned after it. Racing bets are normally void if a meeting is abandoned. Every book on this page publishes sport-by-sport rules; they are not identical.
Should I use more than one bookmaker?
If you bet regularly, yes. Prices differ meaningfully between books on the same market, welcome offers are one per person per site, and having two accounts lets you take the better price rather than the only price. Three accounts covers most situations: a broad book, a sharp in-play book, and TAB NZ for domestic racing depth.
