A truck has rolled on a Waikato stretch of State Highway 1, partially blocking the route and prompting warnings of delays as drivers head home from their long weekends.

Police say the truck crashed north of north of Putaruru in south Waikato at about 6.40am on Monday, leaving one person with minor injuries.

Temporary diversions are in place while the road is cleared, but police say the highway is partially obstructed and causing delays in the area.

"Motorists are asked to seek alternative routes."
