Online Betting NZ [September 2026]: Sports Betting Sites, TAB NZ and the 2025 Law

The law changed on 28 June 2025. TAB NZ is now the only operator that may lawfully offer or promote sports and racing betting to people in New Zealand — and you commit no offence by placing a bet, because the prohibition binds operators rather than punters.
This page covers both sides properly: where TAB NZ is genuinely the better option, where offshore books price sharper and by how much, and how to read an overround so you can tell the difference yourself.

The law changed in June 2025, and most pages have not caught up
Read this before the comparison tables. It is the part that actually matters.
On 28 June 2025 the Racing Industry Amendment Act 2025 came into force. It makes TAB NZ the only entity that may lawfully offer or promote sports and racing betting to a person in New Zealand.
That is a significant change and a great many comparison pages still describe the previous position. So, precisely:
What the Act does
- It prohibits any operator other than TAB NZ from offering betting services to people in New Zealand.
- It prohibits promoting those services to people in New Zealand — a word broad enough to capture advertising, sponsorship and, arguably, affiliate marketing.
- It gives the Department of Internal Affairs enforcement tools including payment blocking and ISP-level measures.
What the Act does not do
It does not make it an offence for you to place a bet. No New Zealand law criminalises the individual punter, and nothing in the 2025 Act changes that. If you hold an account with an offshore sportsbook and bet on it, you commit no offence. The prohibition binds the supply side.
Our own position, since you should know it. This page describes offshore sportsbooks and links to them, and we are paid when you register. The Act’s prohibition on promoting offshore betting to New Zealanders is capable of applying to a page like this one. We think you are better served by an accurate description of the legal position and the market than by silence, but you should read this page knowing both what the law says and what our commercial interest is.
What it means in practice
You have no domestic recourse. If an offshore book voids a bet, restricts your account or refuses a " withdrawal, TAB NZ’s regulator cannot help you and neither can the DIA. Your escalation route is whichever offshore regulator licensed the operator — in almost every case the Curaçao Gaming Control Board. That is a real reduction in protection and it should weigh in the decision.
TAB NZ versus the offshore books, honestly
Most affiliate pages skip this comparison because TAB NZ pays no commission. It is the only lawful option for New Zealanders, so skipping it is not defensible.
Where TAB NZ is genuinely better
- It is lawful, and it is regulated here. A dispute goes to a New Zealand body under New Zealand law. Nothing offshore offers an equivalent.
- Racing. TAB NZ runs the domestic tote and carries depth on New Zealand thoroughbred, harness and greyhound racing that no offshore book comes close to matching.
- Domestic codes. Netball, domestic cricket and the lower New Zealand football grades get real markets rather than a token line.
- Your money funds New Zealand sport. TAB NZ distributions go back into the racing industry and national sporting organisations. Whether that matters to you is a personal question, but it is true and it is never mentioned on affiliate pages.
Where the offshore books are better
- Margins on international sport. Four to five percent better on EPL and NBA head-to-heads, which compounds substantially over a season.
- Market depth on international fixtures — player props, alternate lines and in-play coverage that TAB NZ does not attempt.
- Promotions. TAB NZ is constrained in what it can offer; offshore books are not.
| Market | TAB NZ typical overround | Offshore typical | What that costs you per NZ$100 staked |
|---|---|---|---|
| NRL / NPC head to head | 107–109% | 104–105% | NZ$3–4 more with TAB |
| Super Rugby head to head | 107–108% | 104–106% | NZ$2–3 more |
| ANZ Premiership netball | 106–108% | 108–112% | NZ$2–4 more offshore |
| NZ thoroughbred racing win | ~115% (tote) | Rarely offered | Not comparable — see below |
| EPL football head to head | 106–108% | 102–104% | NZ$4–5 more with TAB |
| NBA head to head | 106–107% | 102–103% | NZ$4 more with TAB |
Read the table as a cost, because that is what it is. A 107% overround against a 104% overround means roughly NZ$3 per NZ$100 staked. A bettor turning over NZ$10,000 in a season is paying about NZ$300 more for the same bets. That is the honest case for offshore books on international sport, and it is real.
It is also the entire case. On racing, on domestic codes and on every dimension of consumer protection, the comparison runs the other way.
Racing is not a close call
Worth separating out, because the answer is unusually clear.
New Zealand racing betting runs on a totalisator — a pool system where all stakes go into a pool, TAB NZ takes a statutory deduction, and the remainder is divided among winners. The takeout is around 15% on win pools, which is high compared with a fixed-odds sports margin.
But offshore books mostly do not offer New Zealand racing at all, and where they do the markets are thin, the limits are low and the prices are derived from the tote anyway. There is no meaningful alternative to compare against.
So for New Zealand racing: use TAB NZ. It is lawful, it is where the liquidity is, it is where the depth is, and the deduction funds the industry producing the racing you are betting on. We earn nothing from saying this.
How to read a price, which is worth more than any tip
The single most useful skill in betting, and almost never taught on pages like this one.
Converting odds to probability
Divide 1 by the decimal odds. A price of 2.50 implies 1 ÷ 2.50 = 40%. A price of 1.80 implies 55.6%. That is what the bookmaker is telling you it thinks, plus its margin.
Finding the overround
Add the implied probabilities of every outcome. In a fair market they would sum to 100%. In a real one they sum to more, and the excess is the bookmaker’s margin.
A head-to-head priced at 1.90 and 1.90 gives 52.6% + 52.6% = 105.2%, so the margin is 5.2%. The same match at 1.95 and 1.95 gives 102.6% — a 2.6% margin, half the cost to you. Identical bet, different price, and the difference is invisible unless you do the arithmetic.
Why this beats tipping
Nobody can reliably tell you who will win. Everybody can tell, in ten seconds, which book is charging less for the same opinion. Over a season, consistently taking the better of two prices is worth more than any run of good selections, and unlike selections it is entirely within your control.
The one number to remember. A 1.90 / 1.90 market costs you 5.2%. A 1.95 / 1.95 market costs you 2.6%. If you do nothing else, compare the head-to-head price across two books before every bet.
Payments, currency and getting paid
The practical mechanics, which differ from casino play in one important way: sports balances tend to sit for longer, so currency costs bite harder.
Currency. Rooster Bet and Bet&Play hold New Zealand dollars end to end. Gunsbet and Ivibet Sportsbook hold euros, costing roughly 4.8% across the round trip. On a balance you top up and withdraw from repeatedly through a season, that adds up faster than most people expect.
Deposits. New Zealand banks increasingly decline gambling merchant codes on cards. POLi is the most reliable domestic route; crypto bypasses the banking question entirely and is supported by three of the four books here.
Withdrawals. The weekly cap governs a large win exactly as it does at a casino — Gunsbet’s €4,000 ceiling is the tightest here. Verify your account when you open it rather than when you win. How the withdrawal clock works.
Betting responsibly, and the specific risk in sport
Sports betting carries a risk that casino play does not, and it is worth naming: it feels like a skill. You follow the game, you know the players, you have a view. That sense of competence is real about the sport and largely illusory about the market, which is priced by people doing it full time with better information.
The specific patterns to watch for are in-play betting, which compresses decisions into seconds, and chasing a losing day with a large bet on a late fixture. Both are where a manageable habit becomes an unmanageable one.
The house edge in betting is the overround. It is smaller than a casino’s, and it applies to every bet you make, forever.
The bottom line on online betting in New Zealand
For racing and domestic codes: TAB NZ. It is lawful, it is where the markets are, and nothing offshore competes. We are paid nothing for that recommendation and it is still the right one.
For international sport: offshore books price four to five percent sharper, which is a real and compounding advantage. Set against that: no domestic recourse, a currency spread at two of the four, and the fact that these operators cannot lawfully offer services here.
Whatever you choose: compare the head-to-head price across two books before betting, verify your account when you open it, set a deposit limit on day one, and treat the overround as the price of the entertainment — because that is exactly what it is.
Frequently asked questions
Is online betting legal in New Zealand?
Placing a bet is lawful for you and always has been — no New Zealand law criminalises the individual punter. What changed on 28 June 2025 is the supply side: the Racing Industry Amendment Act 2025 makes TAB NZ the only entity that may lawfully offer or promote betting services to people in New Zealand. The prohibition binds operators and advertisers.
Can I use an offshore betting site from New Zealand?
You can, and you commit no offence by doing so. What you give up is recourse: the DIA and New Zealand law cannot help you if a bet is voided or an account restricted, and your only escalation route is the offshore regulator that licensed the operator. That is a genuine reduction in protection and it should factor into the decision.
Is TAB NZ better than offshore bookmakers?
On racing and domestic codes, comfortably — it has the liquidity, the depth and the legal standing, and nothing offshore competes. On international sport, offshore books price four to five percent sharper on head-to-head markets, which is worth around NZ$300 a season to someone turning over NZ$10,000. Those are the honest trade-offs.
What is an overround and why does it matter?
The bookmaker's built-in margin. Convert each price to an implied probability by dividing 1 by the decimal odds, then add them up — a fair market sums to 100%, and the excess is the margin. A 1.90/1.90 head-to-head costs you 5.2%; the same match at 1.95/1.95 costs 2.6%. Comparing that across two books before betting is worth more than any tipping service.
Do I pay tax on betting winnings in New Zealand?
Not as a recreational bettor. Gambling winnings are not income under New Zealand law because they are not derived from a taxable activity. The narrow exception is someone carrying on the business of gambling in a systematic, professional way. The full position.
Which sports do New Zealanders bet on most?
Rugby leads comfortably — Super Rugby, the NPC and All Blacks tests — followed by the NRL, which has a large New Zealand following through the Warriors. Racing remains the largest single category by turnover through TAB NZ. Netball's ANZ Premiership has a devoted following and is one of the few markets where TAB NZ consistently prices better than offshore books.
People also ask
Will offshore betting sites be blocked in New Zealand?
The Racing Industry Amendment Act 2025 gives the DIA enforcement tools including payment blocking and ISP-level measures. Whether and how aggressively they are used is a matter of enforcement policy rather than something the Act settles. The practical risk to a punter is disruption to deposits and withdrawals rather than any legal exposure of their own.
What happens to my account if an offshore book stops serving New Zealand?
Reputable operators give notice and allow withdrawals during a wind-down period. This is a strong practical argument for not leaving a large balance sitting in an offshore account — withdraw winnings rather than letting them accumulate, which is sound practice regardless of the regulatory position.
Are betting bonuses better value than casino bonuses?
Structurally, yes, and by a wide margin. A sports offer typically requires 5x or 6x turnover at minimum odds — a requirement a normal bettor completes in weeks. Casino welcome offers commonly require 40x, which on a large bonus runs to six figures of turnover. The minimum-odds condition on a sports bonus has a genuine purpose; a 40x casino multiplier largely has an obstructive one. The casino comparison.
Can I bet on New Zealand racing with an offshore bookmaker?
Rarely, and badly. Most offshore books do not carry New Zealand thoroughbred or harness racing at all, and where they do the markets are thin with low limits and prices derived from the tote. For New Zealand racing, TAB NZ is both the lawful option and the only one with genuine liquidity.
