The search for the body of a 49-year-old Wellington boatie is focused on the eastern coast of Wellington Harbour.
Hutt Valley Senior Sergeant Steve Harwood, who is co-ordinating the search, said the police launch would be searching a large area from around the mouth of the Hutt River south on the eastern coast of the harbour.
"There are some private searches being done as well and we have some staff doing shore searches," he said.
Mr Harwood said the accident was a tragic reminder of what could go wrong when people were unprepared on the water.
The man was with a companion in a small dinghy off the mouth of the Hutt River when they fell into the water just after 5pm on Sunday.
