I just got back last night from a quick work/play trip to New Zealand. I spent ~1 day in Auckland (I had an 8 hour layover so I took a bus into the city) and 7 days in the Lake Taupo/Rotorua area. Here are some of the best pictures I took (1600x1200):

I have a grant looking at the microbes and minerals of the thermal pools of NZ, and a big interest in geochemistry so my sightseeing may not be the same thing that average people look for. Still I think the thermal pools are pretty amazing though to anyone. It was summer there and 25-30C with a good bit of humidity. AKA perfect weather.
