NZ? LOL! I doubt the Maori will welcome you with open arms (check youtube Link).
On the whole i’ve found them to be just like everyone else trying to get along in life, unless you include the militant loonies, but then I don’t think that all of the indigenous UK folk are members of the national front either.
I’ve lived in NZ for 5 years now. I don’t think that i’d return to the UK. NZ isn’t perfect by any means, but I prefer it, but i’m sure that many don’t for what ever reason.
What it is better for in NZ (in my experience) Schools, weather, work/life balance, food and wine, so pretty much most of my needs covered. Health care is very good and TV reminds me of the 80’s.
