Prezoom
Those wanting to order stuff from overseas may be interested in Prezoom. You can order stuff in the UK and US to a local address there, and they then ship it to NZ. Cost is $19.50 for first 1/2 kg and then $4.50 for every 1/2 kg after that.
The NZ Post service is $23.00 for first 1/2 kg and then $10.50 for every 1/2 kg after that.
Hoping some competition will see prices for both firms head down.
