Gambling Tax NZ 2026: Are Casino & Betting Winnings Taxed for Kiwis?

Do you pay tax on gambling winnings in New Zealand? For the vast majority of players, the answer is no. Here's how gambling tax works for Kiwis, including offshore and crypto wins.

Are gambling winnings taxable in NZ?

For recreational players, gambling winnings are generally not taxable in New Zealand. Inland Revenue (IRD) treats casual gambling wins as windfalls rather than income, so a lucky pokies session, sports bet or lottery win is yours to keep — including winnings from offshore casinos and sportsbooks.

This applies to wins in NZD and to crypto winnings converted to NZD, for casual players.

When could tax apply?

The main exception is professional gambling — if gambling is effectively your business or main income (for example, a professional poker player operating systematically for profit), IRD may treat your winnings as taxable income. This is rare and fact-specific. If you think you might fall into this category, get advice from a tax professional or IRD.

Note also that offshore operators may be subject to NZ's offshore gambling duties — that's a matter for operators, not players.

Record-keeping tip

Even though casual winnings are tax-free, it's smart to keep records of large withdrawals — banks may ask about the source of funds, and clear records make verification straightforward.
