Tax on Winnings

Plenty of Kiwis assume that a decent win on the pokies has to be reported somewhere, or that the casino quietly takes a cut for the tax man before paying out. Neither is true for the typical player. In New Zealand, a casual win is simply yours.

The reason this still matters is simple. When you understand how tax on gambling winnings works in NZ, you can enjoy a win without worrying about a letter from Inland Revenue, you know which records are worth keeping, and you can answer your bank calmly if it asks about a large deposit. And the news about online gambling duty rising under the new law makes sense: that change lands on operators, not on your balance.

Everything on this page comes from IRD and Department of Internal Affairs guidance, which we link to so you can read the original wording. We checked each source on 23 September 2026.

Example 1: a casual player wins NZ$2,500 on pokies

You deposit NZ$50 on a Friday night, play a few online pokies and hit a feature that pays NZ$2,500. You withdraw it the following week. That money is yours in full. There is no tax to pay, nothing to put in an income tax return, and no form to send IRD. The amount that reaches your account is the amount you asked to withdraw, minus any payment fee.

This follows IRD's own guidance on prize money: "Generally, if someone wins a raffle, Lotto or prize money in a draw, these winnings are not taxable." It adds that TAB race winnings are not taxable either. Casual casino play sits in the same place. You can read the wording on the IRD prize money page.

Example 2: gambling is part of someone's business

Now picture someone for whom gambling is not a pastime but part of a taxable activity, the way they earn a living. Over a year they stake NZ$120,000 and collect NZ$135,000 in prizes, a net result of NZ$15,000. IRD says that "if prize money is won as part of someone's taxable activity, then it is generally taxable. It must be included as business income". That NZ$15,000 would go into their return as business income and be taxed at their marginal rate. At 33%, purely as an illustration, that would be NZ$4,950.

IRD has no page written specifically for online casinos. In general terms, it looks at whether gambling is part of a taxable activity rather than a hobby. Very few players come near that line; if you might, ask IRD or an accountant.

Example 3: the duty the operator pays

The tax that does exist sits on the casino's side. Say New Zealand residents stake NZ$1,000,000 with an offshore operator in a quarter and it pays out NZ$950,000 in prizes. Its gambling profit from NZ players is NZ$50,000. The 12% online gambling duty on that is NZ$6,000, paid by the operator to IRD on top of GST. Once the rise to 16% takes effect, the same quarter would carry NZ$8,000 in duty. None of it comes out of a player's winnings.

Tax articles about gambling mix up a handful of terms that mean quite different things. Here they are in plain words.

Operators file online gambling duty with IRD every quarter, with returns due on 28 October, 28 January, 7 May and 28 July. The details are on the IRD online gambling duty page. As a player you never see these filings, and nothing on your account statement changes because of them.

The Online Casino Gambling Act 2026 came into force on 1 May 2026, with its regulations following from 3 July 2026. It creates a licensing regime run by the Department of Internal Affairs for up to 15 online casinos. Offshore sites that were serving New Zealanders on 1 May 2026 may keep doing so until 1 December 2026; after that, only operators with a licence, or with an application under review, can continue. The DIA expects the regime to be fully operational in 2027. Its Online Casino Gambling page tracks each stage.

On tax, the Act amends the Gaming Duties Act 1971. "Offshore" becomes "online", and the duty rate goes from 12% to 16%, with 4% ring-fenced for community funding. The start date for the higher rate has not been confirmed; IRD's page still showed 12% when we checked. Licensed operators will also pay the 3.5% DIA levy, GST and the problem gambling levy.

What the Act does not do is tax players. There is no new duty on winnings, no withholding and no reporting duty for casual players. It does add protections: licensed casinos must offer deposit, spend and session limits, breaks and self-exclusion, and cannot accept credit cards or buy-now-pay-later.

For context, Spin Palace is run by the Baytree group (Super Group): Baytree (Alderney) Limited appears on the Alderney Gambling Control Commission eGambling list, and Baytree Interactive Limited holds the Kahnawà:ke Gaming Commission licence 00892 that the current NZ terms are issued under. No online casino holds a New Zealand licence yet.

Tax will not be an issue for most players, but a little record-keeping makes big withdrawals and bank questions painless.
