The incident that saw Porirua's Aotea College thrown into lockdown and students evacuated has come to an end - and police say "there is no current safety risk".
At around 10:30am on Wednesday, police were called to the college after a student received a message on their cellphone with a threat towards the school.
Kāpiti-Mana area commander Inspector James McKay said in a statement to Newshub that following police advice, the college was thrown into lockdown.
"Police officers responded immediately to the school, and helped facilitate the evacuation of students and teachers as a precaution."
Insp McKay acknowledged the distress the incident would have caused to the school's community and thanked them for their co-operation.
After five and half hours, police left the college before 4pm and are confident "there is no current safety risk".
Police are working to identify the person or people involved in the threat.
The lockdown stopped three NZQA exams that were scheduled to be held on Wednesday afternoon.
Aotea College said the NZQA level 1 music, level 2 accounting and level 3 history exams being held at the school will not go ahead.
"All students choosing to sit these exams will need to go to Mana College, where they can take the exams," Aotea College said on its Facebook page.
The school said they will be able to apply for derived grades for students affected by the disruption to both the morning and afternoon exam sessions.
"Any students unable to attend exams on Thursday 10 November due to the effects of today's lockdown will need to contact the school. We will then give them further advice on how they can apply for a derived grade," the school said.
