Yesterday large swells of up to 2.5m hampered the search as it was deemed too risky for the Piha Surf Club's IRB and jet skis to hit the water.
Lifeguards and police officers searched along the beach and around the rocks where the man was swept off and both the Police Eagle and Westpac helicopters carried out aerial searches with no success.
It is the third incident near Piha's Keyhole in the past six months.
A fisherman was given first aid after being washed off the rocks early morning on Easter Sunday and last October three people were swept out of the Keyhole and were rescued by the Piha Emergency Callout Squad using an IRB. In the previous two incidents, the people managed to get help.
