Coastguard efforts are underway to rescue a man stranded on an iceberg in the icy waters of Tasman Lake, near Mount Cook.
Emergency services received a report from the man around 6.10pm, who had taken refuge on an iceberg after his inflatable boat was damaged.
“Other than being cold, the man does not appear to have any injuries,” a police spokesperson said.
Police are not in attendance but it appears either the Coastguard and/or Fenz are trying to get a boat to the area.
