Two people have suffered from moderate injuries after their vehicles crashed on State Highway 3 in Taranaki early this morning.
Police and other services were called to the scene, on Junction Road just south of Egmont Village at 7am, said Sergeant Andy Dow.
He said the south-bound lane was blocked and there would be possible delays in the area.
"We are asking people to please be cautious," said Mr Dow.
Fire service spokesman David Meikle said two appliances attended the scene, and said nobody was trapped in their car.
