A tramper who tackled the Tongariro Crossing in shorts and running shoes remains in a stable condition in Rotorua Hospital.
The German backpacker was airlifted off the mountain on Wednesday after sliding 50m down an icy slope near the summit of Mt Tongariro and taken to Rotorua Hospital.
The man suffered injuries to his feet and legs, and was very cold. The air temperature on the mountain was zero degrees, but there was an added wind chill factor.
A police warning about tackling the crossing with inappropriate clothing and gear was backed today by the Department of Conservation's Jonathan Maxwell. He said "people need to take responsibility for themselves on the crossing".
