A diesel tanker rolled into a ditch on Auckland's north western motorway this morning, during road construction work.
The fire service responded to the incident, which occurred about 8.30am.
"There was a small diesel tanker, a mini tanker, that had rolled," a fire service spokesman said.
"We weren't there for too long. There was no persons trapped or injured.
"It was off to the side of the motorway in the construction zone."
