Hi Ricky,
Top marks for planning your trip before you get here!
Go for layers of clothing that you can add or remove as the temperature goes up and down.
When you say
'nature' what exactly do you mean? I don't think may people would describe Queenstown as natural, although it is surrounded by some pretty amazing countryside.
If you want some suggestions, look at the glaciers on the West Coast of the South Island - they're pretty natural. The thermal wonderland in Rotorua and the Urewera National Park on the North Island are also pretty natural.

Hope that helps
