Auckland's Glendowie College has been put into lockdown this afternoon after reports of a person with a knife.
It's understood the lockdown happened about 4pm and lasted about 10 minutes.
The college's website says the school has now come out of lockdown and all students, staff and person on-site are safely accounted for.
"Everyone did extremely well and responded to instructions. A notice will be going out to parents/caregivers tonight to provide some more information about our emergency lockdown procedures. I would like to personally thank you for your support and trust during this difficult time."
