A teen has been flown to Auckland City Hospital in a critical condition following a jet-ski accident off Kawau Island.
Auckland Rescue Helicopter Trust spokesman Lincoln Davies said the Auckland Westpac Rescue Helicopter crew were tasked to the island at 12.15pm to assist a man in his teens involved in a "jet ski versus jet ski T-bone accident".
An emergency blood transfusion was administered on board a rescue boat by Dr Chris Denny, the trust's doctor.
"The patient was flown to Auckland City Hospital in a critical condition," Davies said.
