A parent contacted the Otago Daily Times alleging an incident had occurred involving two pupils at the school last Tuesday, resulting in one pupil being injured.
Acting Senior Sergeant Anthony Bond, of Dunedin, confirmed there had been an incident at the school last Tuesday but declined to give details.
The incident was being dealt with by the school and police youth aid staff, he said.
Principal Linda Miller said she could not comment on individual pupils due to the Privacy Act.
"However, I can confirm that the school takes strong action around bullying and any behaviours that threaten the safety and wellbeing of students in this school.
"All serious matters are escalated to the board of trustees through our disciplinary processes.
"Where appropriate, the New Zealand Police and the Ministry of Education are contacted."
