The police dive squad were no longer involved in the search mission and the squad had returned to Wellington, she said.
Waihī Beach Coastguard spokesman Jim Pooley said the team of seven searchers were out on the water from first light conducting shoreline searches.
Pooley said both Waihī Beach Coastguard's boats, the Gallagher Rescue and Avoco Rescue vessels, were being used during the search mission again today.
"We've searched the northern Tauranga Harbour right up to Kauri Point and Matakana Island, and down to Waihī Beach from first light, and after high tide this afternoon, we will continue searching again."
Pooley said two lifeguards in an IRB were part of the team searching shorelines.
"We will continue searching as long as it takes," he said.
Police are not releasing further details about the missing fisherman.
A rahui has been placed in the area by elders of three marae - Otawhiwhi, Tuapiro and Te Rereatukahia - prohibiting fishing and the collection of kaimoana.
The rahui is in place until the missing fisherman is found, and at least a week afterwards.
