Firefighters battle large blaze at Auckland trucking company Owens Transport

Firefighters are battling a large blaze at Owen's Transport in Penrose, Auckland.

An employee at a local business said she could see smoke coming out of the warehouse - she understood the fire was in the company's engineering workshop.

Another man who was nearby, Dylan Martin, said the blaze "sounded like a really loud car backfiring".

"Thick smoke started coming up. It seems to have been dealt with as it's just really smoggy now," Martin said.
