The Police National Dive Squad has joined the search for a missing fisherman who washed off the rocks near Waiinu Beach in South Taranaki.
The dive squad arrived on Sunday afternoon and conducted a search in the immediate area where the man had gone into the water.
Day three of the search resumed on Monday with an extended search in the area by the dive squad.
Whanganui Surf Lifeguard Services chairman James Newell said although the conditions were good on Monday, there was no visibility for the divers in the water.
"They can't even see their hand in front of their face," he said.
