Emergency services responded to an incident that was believed to involve chemicals in the Auckland suburb of Mt Albert this afternoon.

Police said they were assisting Fire and Emergency NZ (Fenz) with an incident on Mount Albert Rd, which was reported to Police around 12.45pm.

A spokesperson for the Plant and Food Research facility said a smoke detector in a lab at their Mt Albert research centre was activated earlier today, triggering an evacuation.

“Fire and Emergency NZ attended the site and investigated the event as per their normal procedures”.

“It is not known what triggered the alarm, however, FENZ have confirmed [there was] no risk to people or property and the site had been returned to Plant and Food Research for entry,” they said.

A Hato Hone St John spokesperson confirmed they had earlier dispatched an ambulance to the scene alongside one rapid response vehicle and one operations manager.
