New Zealand is a very small market compared to, for example, Australia. If New Zealanders don't look after their cars, bikes and motorcycles, I imagine they aren't particularly endowed to their cameras and lenses. Do you buy solely from New Zealand, or is there a missing reference to surrounding Oceania e.g. Australia?
You are right about us not looking after our cars.
I buy from Trademe.co.nz and only within NZ, I wouldn't even know how to buy from Aussie.
