The family of an Auckland man who went missing while crab fishing off a Northland beach have maintained a vigil at the beach hoping he is found.
A commercial dive team, paid for by the missing man's family, spent most of yesterday searching a grid pattern in the water just off Uretiti.
They used a side scan sonar attached to the boat which scanned the ocean floor and projected the images on to a screen aboard the boat. A stretch of beach about 1km long on either side of where the 35-year-old Auckland man was last seen setting crab pots was searched with no luck.
Bream Bay police Sergeant Simon Craig said the man's wife and other family members and friends remained on the beach waiting while the search continued.
Officers also did sweeps of the beach but were unable to find any signs of the man, who has yet to be formally named.
