An unconscious 19-year-old woman was rescued by surfers after being sucked out to sea in a rip at Piha Beach yesterday.
Police said emergency services received several calls that two women had been swept to sea near Lion Rock about 2.20pm.
The women, a 17-year-old and the 19-year-old had gone for a swim, but conditions were "poor" with a king low tide and large waves, police said.
A strong rip swept the women up to 200m from shore, with their screams alerting beachgoers to their distress.
Two men, one an American tourist due to fly home today, entered the water and dragged the women to shore.
