Try chatting with someone at the NZ embassy in London.
I read something a year or so ago that NZ were trying to encourage young people to move there, as they had experienced a bit of an exodus of their young, who left the sheep farms in search of more excitement in Europe, particularly Britain.
If you like a party lifestyle, then apart from Auckland, NZ is, how can I put it, a little on the quiet side after about 8pm.
Spectacular scenery, lovely people but very peaceful. Great if you like the quiet life, though.
