Paysafecard (formerly Ukash) allows players from New Zealand to deposit money into their accounts without the need for a credit card or bank account. It's about the easiest way for Kiwi players to turn notes or bills into e-money.
The best thing about using a service like Paysafecard is that you can only play with the exact amount of cash you deposit. If you purchase a voucher for NZD $100, your card is loaded with NZD $100. There's no fee taken out so you can use the entire balance to pay for whatever you want at thousands of online shops, including real money gaming rooms.
