The Police National Dive Squad have returned to a boat wreckage in Haast this morning in the hopes of finding missing fisherman Kieran Lynch.
Lynch, 22, has not been seen since September 14 after fishing boat the Wendy J sank near Smooth Water Bay.
The Wendy J was said to have run aground on the rocky South Westland coast while trying to shelter from a vicious storm.
Sergeant Matt Tailby, of Greymouth Police, said the search of the wreckage would resume now weather conditions have improved.
Police hope they will be able to dive the unexplored stern portion of the wreck that was previously inaccessible.
