She was picked up from the eastern face of Ben Lomond, above a 5m bluff, about 1am. She was flown to Lakes District Hospital and later discharged.
Sen Sgt Fookes said police had yet to speak to her but it appeared she had left the walking track and somehow gone about 100m down a steep snow chute.She was lightly clad and "lucky" to escape without injury or worse.
"She got herself bluffed in very steep and hazardous terrain."
At a time of year when many people got back into outdoor recreation, the incident was a timely reminder they should not underestimate the high country around Queenstown.
"Just because it's accessible doesn't mean it's not dangerous."
People needed to be properly equipped, and tell someone where they were going and when they were due back.
