A police spokeswoman said it appeared someone had tried to go up a gully near Wanaka Mount Aspiring Rd about 3.30pm.
It appeared the person had got stuck on a rock and required assistance, she said.
Units were on their way to assist and it did not seem that the person was in serious peril, the police spokeswoman said.
Update:
A St John spokeswoman said a helicopter attended and transported one patient to Dunstan Hospital with moderate injuries.
