Public concern helped save a 60-year-old hiker who became trapped on a mountain walkway over the weekend, police say.
A person who was concerned about the woman contacted police after spotting her on the Dun Mountain walkway, near Nelson, believing she was not equipped for the conditions.
An appeal on the Nelson Police Facebook page resulted in several people coming forward with information that enabled a search to be mounted, police said.
Two teams of search and rescue volunteers headed into the hills on mountain bikes about 10pm. One of those teams located the woman about 1.30am on the Coppermine Track.
Senior Sergeant Shane Miles said the woman was very cold, but otherwise well. She was brought back down the track and taken for medical assessment.
