Hello I am a British Expat in the US heading to live in Christchurch next year. In the meantime I have several sixty foot containers shipping over the next year to New Zealand from the West Coast of the US. I only have a 50 x 5 x 2 feet part in each for a NZ client. For insurance reasons I can not ship the part LCL. I was thinking about using the empty space to maybe export other commodities for resale. A Kiwi buddy mentioned caravans might be a good idea, in the US the dealers they cant give them away! Any thoughts or other ideas?
