I recently had a pallet shipped from NY to the Gold Coast but it only weighed 280kg's. Door to door with a freight forwarder I use was $1085. Took around 25 days as the ships go to NZ first. USP. FEDEX etc were way dearer.

I used to use a Kiwi guy in Sun Valley, CA when I was bringing pickups over and he would put stuff in his next container but in reality these freight forwarders have good prices and there is no waiting and it's straight to your door.
