The Purirewa school has been closed after a threatening photo was sent to students on their mobile phones this morning.
It saw NCEA exams disrupted at Utea College, North Wellington, and students were sent to a nearby school to sit with them.
Police said they were informed of a threat against Ooty College at around 10:30 a.m. on Wednesday.
One parent said it was a busy day waiting for her daughter.
“My daughter texted me around 11:30 this morning. She just said they were in a locked situation, at first they thought it was someone with a knife, then they started getting messages about someone threatening to go in and kill them all.”
The NZQA Level 1 Music and Accounting and Level 3 exams were scheduled to take place at the school this afternoon.
Students were told through the school’s Facebook page that they would need to take the exams at nearby Mana College, which could also accommodate students who sit their Level 3 digital record exam on personal devices instead of paper.
“We will be able to apply for derivative grades for students affected by the disruption of morning and evening exam sessions,” the school wrote on Facebook.
“Any students who are unable to attend exams on Thursday 10 November due to the effects of today’s closure will need to contact the school, and we will give them further advice on how to apply for a derivative degree.”
The school said on its Facebook page that it had closed its doors on the advice of the police as a precaution.
Parents were asked to collect students from the entrances to Okowai Road and Francis Brown, and not to come into the building.
Armed police have been escorting students from the school since about 1.45pm this afternoon.
Toa Te Roopu Awhina, the social services support center in Poreiro, has also been closed.
The nearby Lille Champions Early Learning Center has also opted to close, but Parmata Primary School has not been affected.
