Cosmo casino bonuses


Newcomers to Cosmo casino NZ are greeted with 150 free spins on the Instant Millionaire Wheel. To be eligible you’ll need to make a first deposit of NZ$10, and bonus winnings can only be cashed out after fulfilling a 200x wagering requirement.

The sign-up bonus at Cosmo casino NZ is not what we’d usually expect, as new players receive 150 spins on the Instant Millionaire Wheel. The best part is right in the name; there is the potential to win a jackpot of NZ$1 million if you get lucky. Given that the minimum deposit to be eligible is just NZ$10, this is a decent deal.

Not so great are the wagering requirements at 200x. This figure may be too steep for most players, and we suggest trying a casino site like Wildz NZ, with wagering requirements of 35x.

This Cosmo casino review did not find any match deposit bonuses, which many Kiwi players do expect. We direct players looking for such promos towards Tonybet casino, which offers a signup bonus of up to NZ$1,000 and 120 free spins. BetandPlay online casino even offers a second deposit bonus of up to NZ$250 as well as 100 free spins.

Compared to the promotions that we're used to at other NZ online casinos, the Cosmo casino welcome bonus may appear too limited for some players. We’d love to see additional free spins offered on more slot games (pokies), or maybe some cashbacks and reloads for loyal players.

On the flip side, if you enjoy playing live casino this contributes 10% to playthrough requirements.

Cosmo casino no deposit bonuses & free spins

Cosmo casino offers don’t include no deposit bonuses as yet, however there is a lucrative system of casino rewards for players. The greatest thing is that, unlike other casinos such as the aforementioned Betandplay or Wildz, you don’t need to climb to the next rung of the VIP club before being able to enjoy an additional Cosmo casino bonus. 

Thanks to Cosmo’s Casino Rewards group, as soon as I joined I immediately qualified for two additional offers: double points on specific slots and the chance to win an NZ$100 lottery when playing casino games like 4 Masks of Inca. Gathering more points means even bigger prizes. 

Cosmo casino site offers other promotions for returning players, including big jackpot draws and sweepstake lotteries with expensive prizes such as luxury getaways, overseas trips, virtual reality sets and more. These draws become accessible as you play games and start climbing up in the VIP club, and they’re big enough to make you forget the lack of match bonuses.

Do I need Cosmo casino bonus codes?

You won’t need any Cosmo casino bonus code to activate your free spins. In truth, these are becoming less and less popular even with big NZ casinos, as they make the player go through an extra step before starting to enjoy their rewards.

If you are looking for NZ casinos that offer bonus code promotions, we suggest that you check out our Winawin casino review, where you’ll find all the codes required for their current promotions.

Games & software: 550+ games powered by Microgaming


Cosmo casino NZ is powered by one of the most popular software provider, Microgaming. Live dealer games are powered by Evolution, and there are some excellent progressive jackpot slots to keep the thrills going.

Game type Number of games Popular titles
Online pokies
9 Pots of Gold, Immortal Romance, Ancient Fortunes
Progressive jackpots
Immortal Romance Mega Moolah, Mega Moolah, Cash Splash
High Limit Blackjack, Vegas Strip Blackjack, Ultimate Blackjack
European Roulette, Auto Roulette, Multifire Roulette
Other table games
Wheel of Winners, Sic Bo, Baccarat
Live dealer games
Crazy Time, Lightning Roulette, Casino Hold ‘em

The majority of games you’ll find at Cosmo casino online are popular NZ online pokies, with all the Microgaming classics like Cash Splash and Treasure Nile. Categories are divided according to paylines and reels, which is very convenient if you happen to be in the moods for a particular style of game. You can also use the search bar to find what you’re looking for. 

The games collection includes 550+ titles. If you prefer more variety, we advise you to give Mirax casino’s 8,000+ library a whirl.

What this Cosmo casino review did find were life-changing jackpots such as Mega Moolah.  Strangely, Major Millions, so popular with Kiwis, is not available. A progressive jackpot prize pool here averages the NZ$3 million and more, so there are plenty of thrills to go around. And if you need some motivation, you’ll be able to see when other players win real money in real time.

The choice of games also includes a good selection of table games and video poker. The only downside is that the software provider for pokies is limited to Microgaming. As a general rule we expect an online casino to be partnered up at least 20 software providers.

Cosmo live dealer games

You’ll find two live dealer lobbies at Cosmo casino NZ. The first one offers in-house live casino games with roulette, blackjack and baccarat options. The second lobby is powered by Evolution and includes all the live casino games the software provider is known for, like Crazy Time, Lightning Roulette and Monopoly Live. 

Buy-ins at both lobbies are good for low-rollers, starting at NZ$0.2 at some tables. High-rollers will also find tables that take stakes of NZ$5,000 and NZ$10,000. There’s a total of 70+ tables to choose from, but if you’d like more variety Winawin offers 300+.

Cosmo online casino payments: 10 methods to choose from


This Cosmo casino review found a nice balance between e-wallets, traditional banking and prepaid card options. This means that even though the banking methods number far less than, say, Winawin’s 16 options, players are still very well served. All deposit methods can be used to withdraw, except for Paysafecard. 

One huge gap is crypto payments. If you’re one of the many Kiwis who nowadays prefer to use crypto, then we recommend checking out our list of the latest NZ bitcoin casinos online.

All the banking options offered by Cosmo casino NZ offer a high level of security and are trusted by the gambling world, as each of them adhere to the strictest standards when it comes to security.

Cosmo casino withdrawal time & other transaction details

We always say it as it is in our reviews: Cosmo casino withdrawals here are not the speediest. There is a pending period of 48 hours, after which requests are processed. Credit and debit card cashouts take three working days, which is one day longer than Quickwin casino.

Even e-wallet withdrawals can take up to three working days to appear in your account. Direct bank transfers take the longest, between 6 to 10 working days, so we would advise against choosing this method to cashout at Cosmo casino NZ. At the time of writing instant banking is not available at the casino.

The minimum withdrawal allowed is NZ$50, which is on the high side. Sites like Winawin allow you to withdraw NZ$30.

Is Cosmo casino legit?


Is Cosmo casino safe for Kiwi players? Undoubtedly, as it is licensed by the Kahnawake Gaming Commission, the Canadian gambling regulator that ensures players’ data and funds are protected.

If you prefer to start playing at a casino with a European license, JackpotCity casino is regulated by the Malta Gaming Authority, another highly-respected regulator. Still, the safety at Cosmo casino online goes beyond licenses, as games are certified to be fair and random by eCOGRA, an independent auditing company. The platform operates with SSL Encryption for 100% security, so you needn’t worry that your data falls into the wrong hands. 

Cosmo casino NZ also offers a full suite of responsible gambling tools, including a self-assessment test, loss limits, deposit limits, the option to take a break and self-exclusion. Moreover, it is partnered up with reputable gambling industry support organisations like Gamblers Anonymous and the National Council on Problem Gambling.

Cosmo mobile casino


There is no online casino app available, but Cosmo casino mobile platform is fully compatible with any mobile device via browser. You’ll be able to access all of Cosmo casino’s titles whether you play online on Android, iOS, iPad or any other tablet, as the site has been developed using HTML5. Just remember to ensure a strong internet connection. 

We tested a variety of devices for the purposes of this Cosmo casino review, and we found the visuals to be beautifully responsive to any screen, without any glitches. The live dealer tables at Cosmo casino mobile also gave us a superb gambling experience.

Customer support: not the fastest


It’s a good thing that Cosmo casino online works so perfectly, because customer support tends to be very slow. The site promises a phone number option, but this was nowhere to be found, which left us with FAQs, email and live chat. 

For starters, live chat is only accessible from one page. We tested it multiple times for this Cosmo casino review, and each time we were left unsatisfied. Initially you’re put through to a chatbot that will ask you for your email address, your surname, your date of birth and your address before it offers you automated link options to the FAQs.

Eventually, we were finally give the option to speak to a live agent, but whenever we tried the shortest waiting time was 36 minutes. The good news is ones we did get through they were a friendly customer service team. Compared to instant responses from 7Bit, this leaves a bad taste. We’re still waiting for the email reply.

Ease of use: simple and convenient


The Cosmo casino log in button is clearly marked at the top of your screen. If you’re joining in for the first time, your first Cosmo casino sign in is guaranteed to be painless and takes less than two minutes.

Making a deposit is the same. The button is clearly marked, you’re taken straight to a list of options, click the one you prefer and you’re done. Important options like banking, FAQs, T&Cs etc are accessible from the bottom menu. The top menu is reserved for categories of games and a search bar. Simple and efficient. 

Cosmo casino online may lack the flashy design of other casino sites like Wildz, but in this case simple works very well and you’ll enjoy a smooth navigation experience.

Conclusion: Delivers on what it promises


Cosmo casino NZ will never score the highest for bonuses or games, for the simple reason that there are so many other sites available to Kiwi players that offer a lot more. It still lacks match deposits or any of the other expected loyalty bonuses, for example.

That said, the operator does offer a range of exciting promotions that include lotteries and sweepstakes with huge prizes, which isn’t as common among NZ online casinos. The games are well-suited both to low and high-rollers as there are plenty of penny pokies and higher stakes option for the serious players.

Moreover, the operator delivers exactly what it promises, which is a stress-free online gambling experience, enough games to keep us entertained, and all the basic payment options we’d expect from an online casino. 

While we’d certainly like to see some improvements in customer support, this Cosmo casino review gives the operator our stamp of approval.
