State Highway 1 at the Desert Road has been closed after a truck and trailer rolled and blocked the road on Monday.

The NZ Transport Agency says a detour is in place via State Highway 49 at Waiouru, SH44, SH47, SH46 and then back onto State Highway 1 at Rangipo.

The detour, which may be in place for several hours, will add at least 40 extra minutes to journeys through the area.

Police say nobody was injured in the crash.
