Well, someone has to be buying the new cars, or else there wouldn't be any used cars.

A lot of new cars are sold to fleets and these eventually come on to the used market.

In 2014, 54% of all car first registrations were made by companies.

Which is lower than I would have guessed, but still significant.

I think NZ imports a lot of cars from overseas. The used-car market is great!

I don't know if it's still the case, but New Zealand used to import a lot of Japanese second hand cars. Cheap, reliable, fuel-efficient and left hand drive.

Less common in Australia because they have (had?) a domestic market to protect -- import tariffs made it less attractive.
