I've lived in AKL for 5 years, yes people seem to be more occupied in lots of other stuff other than sport, and people are not that into their Auckland team, they only attend the finals or the important international fixtures. Smaller cities are more into the community thing and passionate about rugby, cricket etc.
The thing I dislike as most others I've spoken to are traffic, man this is NZ and it takes hours to get anywhere after 7:50am and 4pm, the parking is horrible and small, and d*cks fight for your tiny parking spot (though most ass drivers are quite skilled unlike say Hastings), and the hills, great if you want to lose weight but not on your wallet as a driver. And rains all the time.
But then there is top cafes and Better dressed girls around University, Breakers and disney iceskating, IMAX.
I wouldn't take the "best living cities" thing too seriously, Wellington was voted best city for something, Taipei was voted most livable city and I couldn't last 4 months there! Too many websites these days and anyone can claim a title for tourism's sake. My wife is from China and she'd rather live China, than AKL, it's like the same to her, only one is without her families.
