It was the rain and the humidity. Auckland seems to get more rain than much of the north island in the winter. Coupled with very few living situations having central heating and poor insulation; it can really wear on you. Hamilton was becoming very appealing from a weather and cost of living standpoint(it's also just nice down there too).

Constant weather is a bummer, but the cold and snow doesn't really bother me. As long as I can control the environment of my home without going broke from space heaters and dehumidifiers.

I have a very nuanced opinion of the life style :)I do miss the road trips and coffee. You're right about the opportunities; I may end up back in NZ some day when that's less of a concern.
