I don't have any pictures of New Zealand cities, but I can say some things about them that might be interesting.
(I was going to put a map, but my membership is too new, so I can't.)
Wellington (the capital) is great for the wind, if you don't mind the cold rain coming with it often. It's full of artsy and weird people, especially in the central city. I find them intimidatingly social, and get annoyed with the flakiness, but other people think it's a great atmosphere - cafes, culture, politics etc.
Auckland is just another big city - there's not much point moving to New Zealand if you're going to live in Auckland. It has a corporate feel to it, and terrible public transport, but is more spread out and full of random parks (the green grassy kind) than normal big cities. There are lots of asian people in the central city, and lots of pacific islanders and maori in the south, and a good dosage of people from other countries who've come to check out NZ everywhere else - it has great food, but isn't a good old fashioned kiwi experience. And the humidity is driving me crazy!
Christchurch is a rather conservative city. It has its groups of odd ones like anywhere, but it behaves like a much smaller and britisher town than it is. Nice, but not really memorable.
Dunedin is a student party town with some old people around the edges. I haven't lived there, so I shouldn't even say this much about it.
Rotorua, Taupo and Queenstown, Franz Josef and Kaikoura are tourist-towns - amazing nature, but very loud and commercialized. Nelson and Blenheim are very touristy over summer, but otherwise very nice in scenery and climate.
Hamilton is boring and trying very hard not to be.
Invercargill is fascinating, but very, very cold and isolated. Stewart Island is similar, but more so.
Small towns anywhere in New Zealand will take quite a bit of culture adjusting for anyone from a city. The life tends to be very laid back and the locals may be wary of newcomers. It is my aspiration to settle in a small town in the South Island (somewhere near the snow!) and be a builder, farmer and the local mad cat lady. I expect, and would be happy with good-natured avoidance from the locals.
Friends of mine from the USA say that they are amazed at how little work people do in NZ, and that the super-competitive job culture isn't here. I find my job very stressful already, so I can't imagine how it would be if I lived in the USA.
I like the low population density and pretty nature here, and the possibility of living a sensibly small distance from both beach and snow, but New Zealand has major depression, suicide and domestic violence problems (supposedly worse than other comparable Western modern countries). It is the culture to keep both your problems and successes to yourself - people are seen as weak if they talk about their problems, and it is customary to be mean about anyone who is openly successful. This is only a stereotype of course, but it seems to have some basis in truth. New Zealanders typically are only satisfied when an uncomplaining, tough "under-dog" wins.
Australia is the only other country I would consider living in - I grew up there. The people are (stereotypically) ruder, louder and more friendly, but they have a lot in common with New Zealanders.
