Three people needed medical treatment after an incident at Lake Tarawera early this afternoon.
Emergency services were called to the lake 20km east of Rotorua just after noon, a Hato Hone St John Ambulance spokeswoman said.
It was a “water-related” incident, but she didn’t have further details.
Police confirmed “two or three” people had got into trouble in the lake, but they were now out of the water.
