Ski Queenstown at the following ski fields: Cardrona, The Remarkables, Treble Cone, Coronet Peak.
My recommendation for best snow is Cardrona, but for the most fun Treble Cone.

Park your Campervan for the night at Glendhu Bay Lakeside Holiday Park on the edge of the very beautiful Lake Wanaka.

Heli ski in the Harris Mountains and enjoy your own personal powder and make your own tracks where no one has skied before.
