A Kawerau teenager has died in what has been described as a "tragic incident" while on a school outing at Lake Rotoma today. This afternoon, police confirmed a person had died after a "water incident" at the lake.
In a statement, police said they were notified of the incident at 10.51am.
"The person has since been confirmed deceased."
The death will be referred to the coroner.
In a letter sent to parents and caregivers this afternoon, Tarawera High School principal Helen Tuhoro said the incident happened during a senior outdoor education trip.
"While snorkelling at Lake Rotoma a student suffered a medical event and was attended to by St John's ambulance. We are deeply saddened to inform you that the student has since passed."
All other students involved were safe and returned to school. They were now being supported by whānau, school staff and a counselling team.
"This is an extremely distressing time for both our students and staff."
The school would be closed tomorrow "due to this tragic event".
Tuhoro offered contact details for counselling and support services for both students and their parents and caregivers.
A police spokeswoman said earlier today officers were called to the scene on Matahi Rd off SH30 along with St John.
One person was in a serious condition with medical assistance being provided.
A St John spokeswoman said staff were called out at 10.45am and two ambulances and one helicopter were at the scene.
