A woman was "extremely lucky" to survive a 30 metre plunge into an area marked by jagged rocks at Mt Ruapehu in the Central North Island.
Police said the fall happened at about 8:55pm yesterday when the 29-year-old Dutch woman was tobogganing with a man along an icy track.
The pair slipped and she fell about 30m into the Happy Valley beginner area at the Whakapapa skifield, police said.
Her friend managed to stop his fall by clinging to rocks and clamber up to raise the alarm.
A team from the Ruapehu Alpine Rescue Organisation and Ruapehu Alpine Lifts staff helped rescue the woman, who was airlifted to Rotorua Hospital for tests.
