A Hato Hone St John ambulance crew treated family members at the scene. "He's a hero - there's no two ways about it," Senior Sergeant Dave Wilkinson said. Water Safety NZ Interventions lead Esther Hone said while Stott undoubtedly saved lives, not every rescue attempt was successful. Hato Hone St John encouraged people to call 111 immediately in water-related emergencies, and urged people to learn first aid and CPR.
