If you can, get up to Wanaka from Queenstown (an hour or so on the bus, IIRC). There's a really interesting aviation museum with lots of RAF links, plus I managed to do some great flying from the airport there. The wind was out of limits on the day I visited, so the flying school suggested I tried some rotary flying, for which the wx was ok. Had a brilliant hour doing lesson #1, including some low level along the river bed behind the town, and landing on top of the mountain behind. Great fun!
