A fisherman roped himself to a buoy in Tauranga Harbour after his kayak was swamped with water.
The man, a local in his 40s, was out fishing about 11.30am when he attempted to turn his kayak and started taking on water. He tied himself to a water marker and called for help.
The man was in the water for more than an hour until he was rescued by a man on his surf board and a nearby boat.
Acting Sergeant Andrew Crockett said when the man was brought back to shore, he was very cold and was taken to hospital for a check-up.
Mr Crockett said Jeff Dent, who is visiting from Guatemala and staying with his mother-in-law in Tauranga, was at Fergusson park in Matua and called the police after hearing cries of help from the man at the marker.
