A chemical clean-up is underway at the site of a fertiliser factory fire in Auckland.
More than 60 firefighters were sent to the blaze which gutted the plant off Wharf Road on the Te Atatu Peninsula on Sunday afternoon.
Some of the firefighters had to be decontaminated after getting close to melted chemicals used to make fertiliser.
The Fire Service has largely contained the chemicals, some have seeped into the stormwater system, and contaminated water may have reached Totara Creek.
The creek is now being monitored, while the council's pollution response team is at the burnt-out factory.
