A person has been airlifted to hospital after a fall on the Glacier Burn track in Kinloch, near Queenstown.
Emergency services were alerted to the incident at 2.50pm.
A police spokeswoman said the person was unable to walk out along the track so a rescue helicopter was called and a winch used to get them out.
"The person was transported to hospital in the helicopter," she said.
It was understood the person had a leg injury, police said.
