Bringing my Renault Avantime back to NZ

[muhnkee2]

Hey folks,
I am a kiwi living in London, i have a 2002 Renault Avantime that i have owned for three years, but have now replaced with much more sensible M5.
I know its a lover it or hate it car, but i love it and am struggling to part with it.
Its the same as this one pictured:

I am thinking of shipping it back to Nelson and leaving it there for my Christmas holidays drive.
Can anyone tell me the average cost of shipping a car back to NZ and getting it compliant?

Also, has anyone seen another Avantime in NZ?

Cheers
Greg
