Hi Sandfoot, how did you go sending a board to NZ?
Probably the cheapest would be to send seafreight, ringing freight forwarders and they will consolidate with other freight into container.
You will hear LCL (less than container load) and FCL (full container load).
The disadvantage is the time that you need to get packed in container, sent to wharf and loaded on to ship.
Once it arrives allow a week to get off the ship, trucked to unpack point and then ready for collection or delivery.
Airfreight is the quickest but you pay the price.
I have a lot of business product come via Fed Ex/TNT and wow the freight costs have increased
