A teenaged hiker has been rescued from a mountain top in Marlborough. The girl was part of a group hiking near the peak of Mount Robertson, between Koromiko and Robin Hood Bay, south of Picton. Life Flight helicopter crewman Mike Beausoleil said the girl, from Taranaki, suffered a medical event and was unable to leave the mountain late on Sunday evening. Eventually the group set off a locator beacon to alert emergency services about 1am on Monday, Beausoleil said. ‘‘They were really well equipped, and that’s why they were able to contact us and get the rescue started,’’ he said. But Life Flight was unable to fly in immediately because of low cloud, so a Marlborough Land Search and Rescue team went in on foot to find the group and stabilise the girl. ‘‘They took in survival gear, so they pitched a tent and just waited for the weather to clear. They had to spend about six hours in darkness, trying to keep her warm and comfortable,’’ Beausoleil said. The cloud did not break until about 5.30pm. A Life Flight crew took a Westpac Rescue Helicopter with a Wellington Free Ambulance paramedic on board and winched the girl to safety, shortly before the cloud closed over again and night fell. The teen was flown to Wairau Hospital, in Blenheim, where she was treated and released on Monday night.
