Detective Inspector Kerry Watson told media from the cordon that this was a “critical incident”.

He was unable to confirm any injuries but said there were going to be a lot of police resources in the area.

“It’s going to take us some time to piece together what happened in the events that led up to this critical incident.”

Pakuranga residents reported on social media they had seen at least 14 police cars and a number of armed officers. Ambulances were also in attendance and the police Eagle helicopter was in the air overhead.

Armed police are standing guard on the entrances to the street and a section has been taped off.

Local school Elm Park said a “strong police presence” has responded to the incident.

“Police have responded to, please note there is no immediate danger to Elm Park School,” school principal Sarah Baleicakau said in a message to the school community.

“I have spoken to the police this morning and have been fully assured the school can remain open,” Baleicakau added.

Watson said they would be focused on making sure children got to school safely.

Some residents said they heard what they believed to be gunshots at 6.40am.

“Doesn’t sound great with that many sirens,” one wrote on social media.

“It’s insane. So many sirens,” said another.

For students attending Elm Park School this morning, Baleicakau said: “There is a strong police presence which may inhibit access to the school from Cascades Rd side.”

NZ Police have been approached for comment.
