A South Auckland secondary school was locked down after a number of adults who “presented as aggressive” entered the college grounds this morning.

Aorere College in Papatoetoe said the adults have now been removed from the school grounds “without incident”.

“We will follow up with more information shortly,” the school posted on Facebook.

“Please do not come to the school. All students are safe.”

Principal Leanna Webb said the police attended the incident, and all students have been sent back to class.

She said the matter has been “resolved”.

A police spokesperson said officers were called to Aorere College on Portage Rd, Papatoetoe, after reports an unknown group were attempting to enter the school grounds.

“This group has presented as aggressive, and the school has gone into a self-initiated lockdown.

“Members of staff have escorted the group away and prevented them from re-entering,” said the spokesperson.

Police remained at the school while the lockdown was lifted.

However, they had left soon after and pupils and staff continued with their day as scheduled.

A spokesperson for the principal said they had “sorted the matter internally”.

The incident comes just two months after the school was locked down after an altercation erupted between two family groups on the school grounds.

The school said on June 23 that the lockdown was a “precautionary measure”.

In that incident, police told the Herald there had been a report of disorder between a group of people.

On August 5, Kia Aroha Campus in South Auckland also went into lockdown after an unknown group attempted to enter the grounds.

Police said officers were called to the school on Othello Drive, Clover Park, about 3pm after reports of the incident.

“This group has presented as aggressive and the school has gone into a self-initiated lockdown,” a spokesperson said at the time.

“One person received a minor injury during a scuffle with this group.”

Police said officers escorted the group away from the grounds and the school then came out of lockdown.
