A kayaker who spent around three hours in the Manukau Harbour has been taken to Waitakere Hospital in a serious condition.

Emergency services received reports of a capsized kayak in the water about 200m offshore from French Bay in Titirangi around 1pm.

The kayaker was only wearing an old flotation vest, a wind-proof jacket and pants when he was found by the police Eagle helicopter.

The man claimed he had been floating in the water for about three hours when he was discovered and could hardly talk due to his cold state.


He was located a short distance from where the kayak was reportedly seen and was motionless in the water.

"Eagle liaised with Fire Rescue Service at Auckland International Airport and requested their staff and hovercraft to assist," police said.

"From the air, Eagle staff communicated by using hand signals with the man, at which point he indicated that he was not okay."

An Eagle crew member was tasked to assist the man stuck in the water and stayed with him providing flotation and reassurance until the hovercraft arrived.

A St John spokesperson said an ambulance treated a patient in Titirangi at 1.51pm and transported him to Waitakere Hospital in a serious condition.

Police report the man was suffering from hypothermia.

"Police would like to thank members of the public for their assistance during and after the incident, along with the Auckland International Airport Rescue Fire Service," they said.

"This reinforces the importance of being prepared when undertaking water sports. We encourage people to wear appropriate clothing, have a waterproof means of communication, and let others know your plans so if you encounter unexpected
issues the authorities can be informed."
