Serious two-car crash in Marlborough closes SH63, rescue helicopter on scene

One person is in a critical condition after a serious crash in Marlborough this morning.

Police said the two-car crash on State Highway 63 occurred shortly before 7am on Wednesday at the intersection with Waihopai Valley Rd.

One person is in a critical condition, police said. A helicopter was dispatched to the scene.

The road has been closed and diversions have been put in place, with motorists asked to avoid the area.
