The first thing to do is to stop playing this slot and contact the representative of the casino. This is easy to do, as all casino sites have a support chat. There you will need to answer questions and support will be able to help and explain what happened and why.
Every self-respecting online casino has more than one currency available for the game, but if we are talking about New Zealand casinos, then this is the NZ dollar. But it is worth remembering that this choice is usually made during registration and further changes may only be possible through the casino support service.
It is certainly possible to win, but you will not be able to win a large amount when playing for such bets, even if you win X1000. You will also win cents.
It is possible, but not for everyone. Do not be lazy to check the legality of gambling sites and the reputation of online casinos in the gambling community.
