What is a Cashback Casino Offer?
Cashback bonuses are easy to understand. They award a certain percentage of your losses back, usually in the form of a casino bonus. Cashback generally runs during a specific promo period (for example from Monday to Sunday each week), and the amount you get back is calculated based on your net losses during the timeframe.
While this might not be good news if you’re up, it’s a great way to recoup some losses if you haven’t been very lucky. Cashback casino bonuses might be available across all games on the site including online pokies, live dealer games and table games, or they might be restricted to a certain set of games.
In general, the best cashback bonus casino offers tend to come with 1x wagering requirements, so you’ll need to use the bonus on games before you can withdraw. However, you might find the odd promo here and there where the cashback is credited as real money, in which case you can go ahead and withdraw it if you please.
An important thing to note about casino cashback offers is that they’re often available for returning players rather than newbies. When you sign up at a new online casino site, it might not be as obvious that there’s a cashback promo, so you’ll need to take a look at the promotions section.
But just because you’re more interested in cashback promos doesn’t mean you shouldn’t go right ahead and claim the deposit match, free spins or other welcome bonus that the casino site offers.
You should always do this via a link here at Bookies.com, so that we can make sure you’re actually eligible for the promo. Plus, if there’s a casino bonus code needed for your cashback offer, we’ll list it here to make things even easier for you.

How to Find Online Casino Cashback Offers
Online casino cashback promos aren’t quite as common as other offers like 100 free spins or deposit match bonuses. So you might be wondering how you can make sure you stay up to date with the latest bonuses.
Rather than spending time searching for these promos all over the internet, all you need to do is check this page at Bookies.com regularly. You might want to bookmark it, so you can come back every few weeks to see what’s new.
We’ll be sure to update our online casino list with all of the best sites that have cashback, and when new offers launch, we’ll test them and add to our list if they make the cut. We also keep a close eye on brand new online cashback casinos that launch in NZ, so we can check if they offer cashback.
What Makes the Best Cashback Casino Site?
The best gambling sites do so much more than just offer a good cashback casino bonus - NZ players should also be looking out for other regular promos, a great range of casino games and an excellent user experience across devices. Here’s a quick look at how we review casino sites, so that you know exactly what to look out for.
Percentage of Casino Cashback
It might go without saying that the bigger the cashback percentage, the better. We’ve seen a few sites hand out 100% of losses back after your first day, but these promos are hard to find. A lot of casinos award cashback of 10%, but we prefer when a promo is a little more generous, for example 15% or 20%.
Casino Bonuses
Cashback casino bonuses shouldn’t be the only type of promo up for grabs at your online gambling site. When we review sites, we also look at the welcome bonus (it’s great if a casino offers both free spins and a deposit match), plus we check for regular promos like tournaments, free spins, prize draws, no deposit bonus casino offers and reloads. We also want to see a VIP or loyalty program to reward top players.
User Experience
There’s no point claiming cashback at a casino site if it’s not actually a good place to play. We look for a smooth navigation across all devices, and it should be easy to jump to areas like the games lobby, promos, or your account with just one or two clicks. In general, we tend to find that new online casino sites offer a better overall experience than older ones.
Range of Casino Games
Once you’ve claimed your cashback, you’re going to want to use it on fun games, so this is one of the most important factors. The games lobbies should include at least 1,000 titles, spanning categories like new releases, themed video slots, progressive jackpots, live casino tables, virtual table games like blackjack online and roulette online, bingo and slingo. You might even find a full sportsbook, although the promos are usually separate.
Payment Methods Accepted
The most important thing for us is that all casino payment methods need to be safe and secure. Before you choose a cashback casino site, you should look for payment options like bank cards, POLi, Skrill, Neteller and popular cryptocurrencies. PayPal casinos are another very popular option in NZ.
Payment fees and timelines are also key - the fastest payout online casino NZ sites approve your transactions instantly, so you won’t be waiting around long, as long as you use quick withdrawal methods like e-wallets and crypto.
Mobile Casino App
Online casino cashback sites should all offer a flawless mobile experience, either via a downloadable app or a browser-based site. When we’re reviewing mobile casino sites and apps, we look at the game quality to make sure the slots and table games all work on the smaller screen, plus we analyse the navigation, usability and graphics of the site. Google Pay and Apple Pay casino sites get bonus points for their mobile-first approach.
Online Casino Safety and Security
We always look for the most secure online casino sites - when you spend your own real money, you’ll want to be sure that you’re totally protected. Any good cashback casino sites need to be licensed by a body like the Malta Gaming Authority, so that you can be totally sure the games are fair, the promotions are legit and your money is in good hands.

Responsible Gaming
While casino cashback reduces your risk of losing real money, it’s still important to play responsibly at all times. When we review cashback casino sites, we look for specific responsible gambling tools like deposit limits, loss limits and session time limits, as well as reality checks and a time out feature. All sites should also give you the option to self-exclude, to block access to your account if you feel the need.

Types of Cashback Casino Bonuses
Most cashback casino promos are pretty similar, but there are a few key differences that make each offer unique. These are a few types of promos that you might spot at your favourite online casino site.
Monthly Cashback Bonuses
Cashback isn’t just a one-off. Top cashback bonus casino sites can award the promo as frequently as every month (or even every week if you’re really lucky).
Depending on the casino, you might need to opt in and play during the promo period to get your cashback, or it might be added to your balance automatically. Monthly casino cashback is usually set at around 10% of your losses, so it’s a great way to recoup some of your cash if luck isn’t on your side when playing new slots or other games.
Cashback on Casino Deposits
Almost all of the promos that we list involve casino cashback on losses, so it would be very rare to find a promo that’s based on your deposits. In general, you’ll need to be at a net loss before you can claim any cashback promo. While that’s not exactly good news if you’re winning, it’s definitely a great way to turn around an unlucky streak and online casino real money sites.
Software Provider Cashback
If you’re a big fan of any specific online casino software providers, you’ll be happy to know that some of them have special cashback promos on their games.
These promos are run in conjunction with the online casino site, so all you’ll need to do is play valid games by the provider during the promo period, and if you lose, your casino will credit your account with the cashback amount. We’d recommend using promos like this to try out new releases by the provider and reduce your risk of losing.
Seasonal Cashback Offers
Christmas, Halloween, summer, winter - top NZ online casinos might offer cashback on games themed around the season. There are usually a few specified games that you’ll need to play, and the cashback will be offered on losses on those games only. These offers add a little extra element of fun, and they definitely encourage you to try out new titles that might not have been on your radar before.
Live Casino Cashback Deals
Top online casinos NZ players can understand that not everyone is a fan of pokies - there are plenty of keen live casino fans out there. A lot of sites offer regular live casino cashback promos of up to 20% to soften the blow of losing at the tables.
You can always find the live casino cashback offers in the casino’s promotions section, and you might need to opt in and follow a few key rules to claim. Even if you’ve never played live casino games before, this is a great way to try them out with less risk of losing.

How to Claim Cashback Online Casino Offers
Claiming a casino cashback promo is easy, but you first need to sign up for your account. You should start off right here on this page, where you’ll find short online casino reviews of all of the best gambling sites in NZ.
Click on one of our links on this page to go to the casino of your choice and register. This usually only takes a few minutes, and you’ll need to give details like your name, date of birth, address and email address. You can start depositing and playing immediately, but it’s a good idea to verify your account using your ID and proof of address first, so that you don’t run into any delays when you request your first withdrawal.
Most casino cashback offers are for regular players rather than newbies, so you can also claim a welcome bonus as soon as you sign up. For example, you might get a 100 free spins no deposit promo as soon as you sign up, or you might need to make a qualifying first deposit to get a matched offer or extra spins. You’ll find all the details of the welcome offer here at Bookies.com, or on the sign up page at your chosen casino.
Once you’ve used up your welcome offer, be sure to head to the promotions section to check out the cashback promos. You’ll usually need to opt in to these and play during the specified promo period. You should always check the T&Cs at this point to see if there are any games that are excluded.
Most cashback casino sites credit the bonus money (or real cash) to your account automatically, within about a day of the promo ending. There are some sites that require you to get in touch with the support team to claim your promo, but this will be written clearly in the T&Cs.
Casino Cashback Terms & Conditions
Before you claim any cashback casino offers, you need to spend a bit of time reading the T&Cs of the promo. Here at Bookies.com, we usually try to wrap up the key terms for you, but it’s also a good idea to go through them in detail on the casino site before you claim. That way, you can make sure that you maximise the promo and don’t get caught out by any sneaky restrictions.
If you’ve claimed other casino promos like free spins or a deposit match before, you might have come across the term “wagering requirements”. This is the number of times you need to play through the bonus amount before you can withdraw. Luckily, cashback bonuses tend to have much lower wagering requirements than other casino promos, for example 1x. Some sites place restrictions on how much you can withdraw from promo winnings, so you might not be able to claim something huge like a progressive prize pot.
Some online casinos specify a minimum loss amount to be able to claim the cashback offer, for example it might be set at $100. It’s worth knowing this in advance, so that you can decide whether or not it’s likely
You’ll also need to keep a close eye on the time limits on the promo. Be sure that you actually play during the specified promo period, and if you need to request the cashback manually, check how long you have to do that. There are usually limits on the time you’ll have to meet the wagering requirements too.

Are Casino Cashback Bonuses Legal in New Zealand?
It’s totally legal for you to sign up and play at licensed online casino sites, and when you do, you can claim bonuses like cashback. Here in New Zealand, we don’t license casino sites domestically, but you can use any casino that’s regulated by an international body, usually the Malta Gaming Authority or the Government of Curacao.
Licensed sites can offer a whole lot of different promos including cashback, and as part of their licensing, they have to prove that the promos are fair and transparent, so you can be assured they’re safe to claim.
It’s important to be aware that there are some unlicensed online casinos out there, which might claim to give you huge amounts of cashback, and we don’t want you to fall for potential scam sites. The best way to make sure you’re using legit sites is to stick to the ones we recommend on this page.
