"The driver failed to negotiate a corner and the truck rolled on its side," Mr McLeod said.
"Traffic was reduced to a single lane and there were minor injuries to the driver."
Mr McLeod urged motorists to take extra precautions on the road during the winter months.
"It's getting colder and wet so people really just need to drive to conditions. Give yourself extra following distance and stay in your own lane."
The stretch of State Highway 5 has been the scene of many crashes.
Two people were taken to hospital with multiple broken bones in a crash near Waiotapu in April after a camper van and a motorcycle collided. The motorcycle rider and his pillion passenger suffered "life-changing" injuries.
Two Australian tourists were killed and seven others injured in a crash in November when their van crossed the centre line and collided with a milk tanker, south of Settlers Rd, in Reporoa, and in October last year a tourist making a U-turn on the same highway outside the Waiotapu Tavern was hit by another car. Four people were injured.
The New Zealand Transport Agency recently spent about $400,000 improving safety on State Highway 5 near Waiotapu.
