Homes and businesses in Auckland's Kingsland are being evacuated as emergency services rush to an "incident" involving a hazardous substance.
Hato Hone St John told Newshub one person has been taken to hospital in a moderate condition.
A Fire and Emergency spokesperson said they were called to the scene about 1pm on Monday.
"There are eight crews in attendance, supporting other emergency services. Crews are working to neutralise the substance and are monitoring for contamination and odour spread," the spokesperson said.
The product has been removed and neutralised, but firefighters remain onsite checking the house for any other hazards.
A police spokesperson told Newshub officers were assisting firefighters at an address on New North Rd in Kingsland.
"There are concerns for a person's wellbeing," the police spokesperson said.
"We are evacuating some homes and businesses in the area as a precaution."
