Casino bonuses in New Zealand

• Welcome deposit bonus. The casino adds a percentage of your first deposit as bonus money, for example 100% up to NZ$100. You must bet it a set number of times before it becomes cash.
• Bonus spins with a deposit. Spins on a named slot, given when you deposit. Each spin has a fixed stake, and winnings usually carry wagering.
• No-deposit bonus. A small amount of bonus money or a set of free spins you get without depositing. These are uncommon, small, and usually come with tight caps on what you can cash out.
• Cashback. A share of your losses returned over a period, often as bonus money with its own wagering.
• Reload bonus. A deposit bonus for existing players, with the same kinds of terms.

Wagering is how much you must bet before bonus money becomes cash you can withdraw. Here is a NZ$20 deposit bonus worked through. The figures are an example, not any casino's offer.

On average, betting NZ$700 on a game that returns 96% costs about NZ$28, more than the NZ$20 bonus. That's an average over a very large number of bets, and any single session can go better or worse. If the 35x applies to deposit plus bonus, you'd need NZ$1,400 in bets and the average cost doubles to about NZ$56. Table games often count for less than slots towards wagering, so check the contribution rates.

A bigger headline isn't always better value. Here are two made-up offers, each taken with a NZ$50 deposit, compared on what the wagering would cost on average at a slot returning 96%.

Offer A looks twice as generous, but on average its wagering costs more than the bonus is worth. Offer B is smaller and far easier to clear. These are averages, and real sessions vary a lot.

• Max cash-out. Many bonuses cap what you can withdraw from bonus winnings, for example at NZ$100. Anything above the cap is removed when you withdraw.
• Max bet while wagering. Bonuses usually limit your stake per spin or hand while the bonus is active, for example to NZ$5. Bigger bets can void the bonus and its winnings.
• Expiry. Bonuses and spins have deadlines. Spins can expire within a day or two of being credited, and wagering often has to be finished within a set number of days.
• Excluded methods and games. Some offers exclude deposits made with certain methods, and some games don't count towards wagering at all.

The value of a batch of spins is the number of spins multiplied by the stake per spin. That's what you would pay to play the same spins yourself.

Winnings from spins are usually bonus money with wagering. NZ$4 of spin winnings with 40x wagering means NZ$160 in bets, which costs about NZ$6.40 on average at 96% RTP. Spins you get without a deposit cost you nothing to try; spins given for a deposit are part of what you paid for, so we call them bonus spins.

• Withdrawing cancels the bonus. Asking for a payout before wagering is finished usually removes the bonus and anything won with it.
• One offer per person or household. Opening a second account to claim an offer again can get both closed and winnings held back.
• Wagering on winnings, not the stake. With spins, the wagering usually applies to what you win, and it starts only once the spins are played.
• Bonus money is used last, or first. Terms differ on whether your own cash or the bonus is spent first, which affects what you can withdraw if you stop early.

You don't have to take a bonus. Decline it if you want quick access to any winnings, if you can't realistically finish the wagering in time, or if you're depositing to win back a loss. Playing with your own cash keeps things simple: whatever is left is yours to withdraw. If bonuses keep pulling you back, set a deposit limit or call the Gambling Care helpline on 1800 936 725, open 24 hours a day.
