Emergency services were called to Bulls Paddock in the Booti Booti national park area at 9.20am, a NSW Ambulance spokesman said.
Colin Rowland had been surfing at Seven Mile Beach, just south of Forster, on the NSW Mid North Coast when a shark, believed to be up to 3.5 metres long, attacked him.
He then swam to shore, suffering puncture wounds to his foot and arm, and called emergency services, NSW Police Media said.
A large chunk of Mr Rowland's surfboard was bitten off before he made it to shore.
Hunter Westpac rescue helicopter crewman Graham Nickisson told the Newcastle Herald: "[Mr Rowland] said: 'I have been surfing for 54 years and this is the first time I have even seen a shark, so I am pretty lucky'.
