UPDATED 9.55pm: The search will resume at first light tomorrow for a man missing after a boat was swamped in Lake Rotorua.

Five men were in the vessel when it sank around 5:45pm.

Four of them were pulled to safety by a local in his own boat.

They are being treated in Rotorua Hospital for hypothermia.

But no trace has been found of the fifth man, despite a Coastguard search until the light faded.
