Alpine Travel Trailers What To Pack Traveling To NZ October 2009?

What to pack traveling to NZ October 2009? - alpine travel trailers

My partner and I are traveling to New Zealand on 09 October and are wondering what to bring. We drive an RV around the two islands and are wondering what to pack. We would like to spend more time in the glaciers of the South Island and the trip to the Alps. Since the October snow gear or just plain clothes, for example, hot jeans and a sweater.
From Sydney, we did not really experience the cold climate as such.
Can anyone tell how cold it is and what it is.

Thanks
Carly
