A diver was rescued at Maketu early last night after spending more than four hours floating in the water.
Two people set out from Maketu yesterday with one diving for crayfish while the other manned the boat.
The boatman lost sight of the diver so returned to the beach and raised the alarm with police.
Maketu Coastguard spokesman Shane Beech says that triggered a full-scale rescue operation involving the surf life saving club.
Shane beech says the helicopter crew spotted the diver in the water and he was hauled to safety.
