Importing regulations into New Zealand

Can any of the kiwi members advise me on the pros & cons of importing into New Zealand. Just started out and willing to soak up all the info from experienced members in the forum.

Shipping is expensive because NZ is so far away from other countries, but on the bright side, because NZ has to import so much stuff import duties are often quite low - particularly with countries NZ has trade agreements with, which you can find here: Link hidden: Login to view. The big thing is to buy in big enough bulk lots to reduce the shipping cost per unit.
