Bayfield High School in Dunedin’s Anderson’s Bay is now closed after a threatening email was sent to the college as students arrived for class.
Armed police are escorting students from the school in groups of four as they work to establish the origin of the correspondence.
The school was initially placed in lockdown before a decision was made mid-morning to call off classes for the day following the online threat.
An email from the school principal to parents about 8.35am said the school was in lockdown effective immediately, and all students would remain on site.
About 50 parents were gathered outside the school, with small groups of students seen being escorted off the school grounds to the crowd.
Police confirmed they were investigating a threatening email sent to the school this morning, having been alerted about 8 o’clock.
Police were working to establish the origin of the correspondence, a spokesperson said.
Cordons were in place and a visible police presence would remain in the area while inquiries were ongoing.
A person at the scene said an alarm was going off, and a group of people had gathered at a nearby crossing.
A parent wrote on social media their son had texted saying they were locked down in class, and armed police were clearing people from a nearby inlet who were walking dogs.
In November, Bayfield was locked down for two hours after an online threat.
