St John Ambulance and Mangonui police also attended.
It is understood the man had only recently moved to the Karikari Peninsula from Auckland. His name has not yet been released.
The coroner would decide whether to conduct a post-mortem examination to confirm the cause of death.
Police and an ambulance were called about 3.10pm after the man was pulled onto the beach opposite the Whatuwhiwhi Top 10 Holiday Park, Senior Sergeant Cliff Metcalfe said.
Members of the public performed CPR on the man, he said, but he was pronounced dead when an ambulance arrived.
Police were still trying to identify the man, Metcalfe said.
