Hey there, welcome to Geekhack!
I think the best people to advise you would be Australians. I know there are a few on here, don't know how many Kiwis we have, but the Aussies can definitely give you a hand in terms of where to buy from and what shipping charges to pay.
Also you need to have a good idea of your price range, if you want backlights or not, and how big you want your board to be. Then we can give you a rough idea of what to look into buying
