Stop when the bonus stops being fun

Take the bonus only if the playthrough suits your budget. Nothing about it obliges you to keep spinning: you can walk away mid-clear and lose only the bonus and its winnings. Set limits before your first bet, and the tools below stay live across every session. Free help is available from the Problem Gambling Foundation of New Zealand, Gambling Helpline New Zealand and the Multi-Venue Exclusion Programme.

Deposit limits. Caps what you can put in over a day, week or month, so the next deposit has to wait.

Cooling-off period. Pauses your account for an agreed stretch, keeping the break fixed rather than a promise.

Self-exclusion. Blocks your access for a longer term and can be extended to venues outside this site.

Getting started

Four steps to an activated welcome bonus

You will know exactly what to do from opening an account to clearing the wagering.

Greatwin Casino sign-up

How much do I pay in?

Deposit at least NZ$19 by Visa, Skrill or another listed method, and note that the match tops out at NZ$300.

Bonus credit on deposit

Activate the offer as you deposit so the 199% match and 146 spins land in your balance, and check the 30-day clock.

How long to clear it?

Play through the 26x wagering, tracking progress, and finish it before the 30 days are up or the bonus lapses.

Greatwin Casino, plainly

What should I ask before claiming?

Clears up the code, the clock and the wagering maths that trip people up most.

trustCan I claim the welcome offer without a promo code?+

Check the promo code page here for every current code, including the one attached to the welcome offer. Codes change, so read the offer card on the day you deposit rather than relying on one you saw last month. A code entered wrongly can void the match.

trustHow long has this casino been licensed?+

Malta Gaming Authority holds the licence, number MGA/B2C/186/2010, and it has run since 2010. That regulator sets the conduct rules this site follows. New Zealand's own licensing regime sits separately on top of it, covered further down this page.

trustCan I leave the bonus sitting in my account for a month?+

Claim inside 30 days and clear the wagering before that same window closes. Bonuses left untouched are removed, and any winnings still locked to them go too. Diarise the last day rather than trusting memory.

trustWhat happens once the welcome bonus is used up?+

Log back in weekly for the cashback offer, which returns 5% of losses with no wagering attached. Free spins also land for 14 days as part of the welcome package, so existing players keep earning past the first deposit. Regulars get more from the loyalty ladder.

trustCan I withdraw winnings before meeting the 26x wagering?+

Wagering means you must stake the bonus amount 26 times before withdrawing anything won from it. A NZ$199 bonus therefore needs NZ$5,174 played through. Until then the funds stay locked, so read that figure before you opt in.

trustWhat happens if I skip the bonus entirely?+

Decline the offer and every deposit and win stays yours, with no playthrough to clear and no expiry date chasing you. Choosing no bonus simply means smaller balances but total freedom to withdraw. Many players treat the first deposit as a paid trial.

trustWhat if my phone loses signal while I am wagering?+

Use the mobile browser version and the bonus works the same as on a desktop. Sessions survive a dropped connection, so a bonus round will not vanish mid-spin. Check your data allowance before starting a long playthrough.

Running the maths

A small deposit, a big playthrough

The amount to wager is the bonus times 26x wagering, so a NZ$60 bonus means NZ$1.552 to play through.

Keep the whole bonus

Four slips that cancel a bonus

Clears up the most common worry: that a bonus is withdrawn over a detail nobody told you about.

Tick the offer, then pay

Depositing before you tick the welcome offer leaves the payment as a plain deposit, and the match is gone for good from that account.

Opt in on the bonus page first

Check the bonus shows before paying

Watch the expiry date

Your match and spins carry a 30-day validity, and the balance plus winnings are removed once those days run out with wagering unfinished.

Check the expiry date in your bonus list

Clear a slice of wagering every week

A second sign-up costs you the first

Only one account is allowed per player, so a second one opened for another welcome offer is closed and its balance goes with it.

Use your registered email every time

Ask support to unlock a forgotten login

Your NZ$10 top-up earns nothing

Anything below the NZ$19 minimum deposit does not trigger the match, so a small top-up lands as plain funds with no bonus attached.

Pay in NZ$19 or more in one go

Check the amount before confirming
