Take your pick
My favourites are Pauanui and Matarangi, both on the east coast of Coromandel and 30ish minutes from Auckland. I haven't been to Whitianga for a while, so am not up to date with the developments there.
Idea: why not find some beautiful real estate near the ocean with a nice climate and surf? Convince a developer to jump in and create a nice new airpark. Then you buy the properties while they are cheap, and sell them on later, thus paying for your own piece of paradise.
Maybe I'm dreaming...
ECT?
