The school's principal Mary-Jeanne Lynch said the threat was being taken "very seriously".

She said police have no concerns for the safety of staff and parents attending the school tomorrow, and they have full confidence in their approach.

The school also notified staff and parents this evening.

Today's incident comes after six North Island schools were either thrust into lockdown or evacuated following threats made towards the schools over the phone on Tuesday.

Matamata College, Matamata Intermediate, Thames High School, Cambridge High School, Firth Primary School and Lytton High School all announced they had received threats and were either evacuating students, or had gone into lockdown.

It is not known at this stage if the threat today is linked to yesterday's phone calls.
