"The police officers investigated and determined that there were no specific safety risks."
McAllen said that upon following the advice of the police officers present immediately on site, it became clear the automated incoming phone call was linked to a number of other calls to schools throughout the North Island and South Island on Thursday.
"Police extends thanks to the schools involved for following their emergency procedures, and to the wider school communities for their co-operation," a police spokesperson said.
On Tuesday threats were made to schools in Waikato, Thames and Gisborne.
Leader of operations and integration at the Ministry of Education, Sean Teddy, said it was aware that multiple schools across the country had received the threat.
"All schools and kura have established emergency management protocols in place, which they activate if a risk is identified.
"We are in contact with those schools and kura that received the message to provide guidance, if needed."
