Emergency services have rushed to an Auckland business where a bitumen tank is believed to have caught fire this morning.
The Herald understands it's the same Mt Wellington Fulton Hogan site where a worker suffered burns due to a chemical spill yesterday.
Today at 7.46am fire and emergency services were called to the scene for a fire in a bitumen tank.
A fire and emergency spokesperson said two fire appliances were responding to the incident.
"It is nothing major at this stage."
The Herald understands no one was injured or hurt.
A WorkSafe spokesperson said it had been notified of two incidents at Fulton Hogan in Mt Wellington, and was continuing to make initial inquiries.
"This is not an investigation at this stage."
A Fulton Hogan spokesperson said this morning the company had the fire service checking hotspots identified as part of the clean-up process.
The spokesperson said the company was investigating the cause of yesterday's workplace accident which left a worker injured.
"The subcontractor was discharged from hospital last night.
"His injuries are minor in nature, and he is expecting to be back at work today or early next week."
Company staff had been supporting the worker through this incident and were present at the hospital yesterday, the spokesperson said.
"A full investigation is presently under way."
Seven people have died in road crashes around the country since Wednesday.
