An injured German woman who fell into a crevasse above Fox Glacier has to stay in the freezing conditions overnight.
Rescuers say the 34-year-old woman was climbing on the Western side of Glacier Peak, almost 3000 metres above sea level, when she fell between 10 and 20 metres, severely injuring her arm and leg.
Rescue helicopters were unable to reach her because of cloud cover and were stood-down for the night.
Three members of the Alpine Cliff Rescue team are spending the night with the woman.
Solid Energy rescue helicopter pilot Martin Shaw says his team had to stand down for the night because it was too dark to attempt a rescue.
Shaw said the rescue team staying with the woman have equipment with them to stay warm. He said she is in a stable condition and is secure and warm.
The Mount Cook Rescue Helicopter is staying at Pioneer Hutt on the Glacier overnight and will try to reach the woman at first light.
