One person has been hospitalised and multiple have been treated following a chemical-related fire at Fonterra's Whangarei factory.
Fire and Emergency New Zealand (FENZ) spokesperson and shift manager Craig Dally said the fire was caused by an electric pump motor.
Dally said multiple people were treated by ambulance staff at the scene.
Three fire crews initially responded to the incident at 7:30pm, seven attending the scene in total.
Dally said a small fire was extinguished before the arrival of Fire and Emergency crews.
"Several unidentifed chemicals were involved," he said.
"The fire was possibly caused by an electric pump motor."
A Fonterra spokesperson said the site has been cleared and staff have returned to work.
The incident occurred at Fonterra's factory on State Highway 1 in Kauri, north of Whangarei.
