A rahui remains in place over a small part of Lake Rotoiti, as the search continues for a man who is presumed drowned after jumping off a boat on the lake on Wednesday.
The 48-year-old Auckland man has not yet been found, despite more than 16 hours of searching more than 3haof Lake Rotoiti by the police dive squad.
The man, described by his brother as a strong swimmer, jumped off the boat to retrieve his hat when it blew off. His lifejacket came off and he drifted away from the boat, where his partner and 9-year-old son were unable to get to him.
Three extra divers joinedthe search yesterdayand a special machine was brought in to help with the search.
Rotorua Constable Colin Fraser from Search and Rescue said the machine, a sonar, meant they could search areas without the divers.
