Police have released the name of the man who died while swimming at Long Beach, Russell, on Saturday.
He was Lino Costy Hellesoe, 53, from Red Beach in Auckland.
Mr Hellesoe was body surfing when he got into difficulties about 4pm.
Two men and a woman, who was believed to have been an off-duty ambulance officer, tried to resuscitate the man for around 15 minutes until emergency services arrived and took over.
A witness said they were "taking it in turns" to provide CPR, but the man died at the scene.
