Not far from Queenstown is a place called Steep White. Its up by Mt Larkins and you can heli in from Queenstown or if your real keen hike/skin from Glenorchy. We went there recently for a Diaries Down Under trip. Expectations were pretty low due to the recent snow conditions and weather forecast but we were pleasantly surprised with how the trip went, the terrain, the hut and even the snow was amazingly good. Definitely recommend getting up there if you get the chance.
