Searchers have recovered debris from the inflatable dingy belonging to the wreckage of crayfishing boat K'Cee in Doubtful Sound but the two crew remain missing.
In good weather conditions, six vessels and three helicopters continued the search today for skipper Bruce Gordon and Darren Allen.
Searchers recovered two wooden floorboards from the inflatable dingy about 10km north of Secretary Island and a bladder from the inflatable life raft, 400m from Noon Extreme Point on the island.
The emergency locator beacon from the K'Cee has been found on the beach with minor damage, but had not been activated, said police.
Water, air and land searches for the crew have continued since yesterday morning. However, after finding the items from the boat, the outcome was looking "less hopeful'', said police.
