It comes the same day as Dunedin’s Bayfield High School was placed in lockdown after an email 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.
“Please keep your son or daughter at home if they have not left for school yet.”
Armed police could be seen turning away parents outside the school. About 50 parents were gathered outside the school, with small groups of students seen being escorted off the school grounds to the crowd.
The decision was then made mid-morning to call off classes for the day.
Police were working to establish the origin of the correspondence, a spokesperson said.
