I have previous looked at buying some metric cartridge brass from Germany and the gunshop that I was dealing with was Grauwolf (www.grauwolf.net). They had advised that they would be able to send brass and projectiles to New Zealand. They should be able to provide you with 6.5x57R bass (I have provided these details to someone else and they were able to bring in some RWS 6.5x68 RWS brass). Hope this helps.
