Hi Paddy,I operate a service selling Bitcoins to people for cash in the mail for UK/EU users.Although it hadn't even crossed my mind last week a client got in touch and asked if I would be willing to process an order from NZ. I looked into this and asked on the forums and found that it's actually quite easy to ship from NZ to the Uk (about 4 working days) and it's possible to insure your money through an International Express option too.I am not saying that you have to use my service by any means (although you're most welcome to!) but it seems to me using BitNZ wouldn't be very safe as I understand you have to show ID to wire them money. Of course if the original purchase of Bitcoins can be traced to your original wallet address this reduces your safety so even if you don't want to use my service I'd suggest buying your BTC with cash.All the best,V.
