My cousin lives there (he's in his 40s and rather rich). Anyway I've been and it's more or less similar to England in the winter. The women come after the dudes there. Yeah even me. Things are expensive. People are liberal and gay. Everybody does extreme sports. Mauris are mostly tossers. Not too many good looking women. Lots of British people. The women come after the men there.
Did I mention the women come after the men there?
Oh and there's mount monganui (or something), steaming rock pools, grumpy old dudes that give you unwanted advice, bimbos.. uh not much else.
It has the rough and readiness of Australia to a degree, but with a hint of gayness thrown in, basically.
