The actions of the trio, who failed to return after leaving Rangaunu Harbour in a five-metre aluminium boat on Friday afternoon, attracted strong criticism from Maritime NZ deputy director Lindsay Sturt.
"It sounds like these fishermen failed to follow all the basic rules," he said.
"It's not rocket science. It is quite simple to make sure you are wearing a life jacket, let people know where you are going and when you will be back, and take a communication device, even if it is just wrapping a cellphone in a plastic bag.
"There are plenty of water safety messages out there, but sadly, some people, usually men, are ignoring them. They have an attitude of 'she'll be right' when often that is not the case at all. They over-estimate their abilities while under-estimating the risks."
The men had been reported overdue at 1.12am, Coastguard Radio using VHF to appeal for sightings of the boat and launching a search by the Northland Air Patrol and Coastguard Houhora volunteers, using a private vessel, at first light. The Northland Air Patrol found the upturned boat at 6.30am, Coastguard Houhora arriving soon after to find three people on rocks. Unable to reach them due to rough conditions, one of the trio swam to the Coastguard vessel, telling the crew that one of his friends was suffering severe hypothermia and the other had sustained several gashes.
The rescue helicopter was called to winch them to safety.
