The search for a missing swimmer at Piha was called off late last night, police say.
A police spokesman confirmed earlier this evening a man aged in his 20s disappeared near Lion Rock, and a second swimmer needed medical treatment from surf lifesavers in the incident just after 6pm.
St John Ambulance later confirmed the second swimmer had minor injuries and was not taken to hospital.
A land-based search was due to begin after 8am today, when low tide is expected, the police spokesman said.
A Surf Life Saving spokeswoman said both swimmers were men and got into trouble after being caught in a rip.
"Public raised the alarm with lifeguards at 1750 hours on scene and an IRB was launched. Lifeguards from Piha Surf Life Saving Club and United North Piha lifeguard service were involved in the search.
"One person was rescued by Piha lifeguards upon arrival. One male in his mid twenties is still missing. The on-water search carried on for over an hour in extreme conditions."
Auckland Westpac Rescue Helicopter, the police Eagle helicopter, Northern Coastguard were also involved in the search, along with five Inflatable Rescue Boats.
