Waikato's State Highway 1 Huntly Expressway has been closed to northbound traffic this morning due to a large truck fire.
Five fire crews were called to the blaze, north of Orini Rd, about 4.15 this morning.
Newstalk ZB listener Brian was among the first at the scene, and said he saw the truck alight.
"A large B-train, from what I could see when I went past, carrying packaging or something. When I went past it was still roaring."
