An Auckland school has pulled its students out of this week's Polyfest due to a brawl believed to have involved weapons.
Police with aerial support were called to Aorere College in Manukau last Friday after a fight broke out on the rugby fields.
One student was injured during the incident, believed to have been started by five students egged on by dozens of bystanders.
Aorere principal Patrick Drumm told Radio New Zealand the school would not be taking part in this weekend's Polyfest due to "security concerns".
"[It was a] very, very difficult decision for us. This would have been our 38th year in a row as a foundation school."
