Searchers have failed to find any signs of an experienced seaman who went missing in the Marlborough Sounds three days ago.
Kerry Blair, 55, was last seen near Cape Jackson about 5.30pm on Saturday.
Sea conditions at the time were calm.
His brother Peter told APNZ that several planes had spent the day searching for signs of Mr Blair today.
An extensive water search of the Marlborough Sounds, as well as the area between Nelson and Greymouth had also been undertaken in in the past few days, he said.
