There a new way to top-up ur vodafone mobile. u can use ur ATM card, and it doesn't have to be at an ATM machine!. u can top-up straight from ur fone. U can read all about it here:

http://www.vodafone.co.nz/

Then click on "PAY BY MOBILE"

And then read the guide on the site.

basically u set the service(as it says on the site) and u programme ur ATM card into ur vodafone account(it tells u how to do this) then whenever u need a top-up u just use ur fone by going into a special menu and typing in the amount u wanna top-up and type in ur ATM card pin code and its done.it takes the money straight out of ur bank account.

For this service u need a new sim2 sim card. it tells u how to get a new sim2 sim card on the site. It's only $10 from any vodafone store. they transfer ur number from ur old sim card onto a new one, so u keep ur same number. U will however need to write down ur ADDRESS book and saved text messages that u have because they won't be transferred onto the new sim2 sim card.U WILL still have ur current prepay account balance on ur NEW sim2 sim card which is great and it also comes with $10 free airtime.
