Conservation Minister Steve Chadwick opened the 9400 hectare Whakaari Conservation Area at the head of Lake Wakatipu.
The mountainous area featured beech forests, historic mining huts, kea, falcons and rock wrens as well as alpine plants.
"This a massive outdoor playground that is now open to all New Zealanders and visitors for tramping, mountain biking, skiing, bird watching and other activities," Ms Chadwick said.
The name Whakaari meant elevated land.
The land has returned to Crown ownership as part of the Wyuna pastoral lease tenure review.
Activities in the new area included:
* a half day walking track to the Government Battery with views across the head of Lake Wakatipu;
* a full day walk or mountain bike trip further into the mountains along the Mount Judah track, which includes scheelite mines;
* a more strenuous day walk or mountain bike trip on a loop taking in the Mount McIntosh workings;
* overnight tramping trips to historic mining huts;
* heli-skiing and ski mountaineering in winter.
The Minister also opened a new facility for trampers and visitors at the end of the Routeburn track which about 60,000 people use each year.
It included a new shelter with flush toilets, wash basins and local information, parking for buses and cars, and better traffic flow for peak times.
The cost of the Routeburn development was $927,191, and was funded through a 10-year $346 million investment from 2002 for Department of Conservation visitor facilities.
