I am traveling to New Zealand and enjoy adventure travel (bungy, sky dving, etc.) where should I go and do?

There’s bungy jumping almost everywhere in New Zealand. Where there’s a bridge, high mountain ridge, there will likely be a bungy-jumping company there. There’s one in Auckland, at the Sky Tower or jumping over the Harbour Bridge. There’s also one in Taupo, if you want to stay in the North Island. But if you want to go for the extreme, try Queenstown or Wanaka. There will be many bungy-jumping companies there too, as well as ski resorts in both locations.
In the South Island, there are snowy mountains and glaciers, especially in the Southern Alps, where you can do some skiing. In the North Island, there is Mount Ruapehu, next to Rotorua, and I think that’s it.

Apparently though, “The New Zealand ski season is roughly early July to early October”, so if you’re really lucky, there may still be some snow left. Although, judging by the weather now, I think the snow will stay for a while yet, since it’s still hailing in the middle of summer… O_o
I’ve found sites with excellent information for adventurous people like you ;) Hope they’re of use.
Have fun when you come to New Zealand!
