Two people have been injured, one critically, after a crash on the main road between Christchurch and Banks Peninsula.

The crash was reported just after 9am this morning.

The crash is between Turrells Road and Kaituna Valley Road intersections with SH75 near Prices Valley.

Police have closed SH75, the single highway between Akaroa and Christchurch south of Motukarara.

There is no detour route. 

“People are encouraged to avoid the area until it reopens, which may take some hours,” says Waka Kotahi NZ Transport Agency Maintenance Contract Manager Steve Rusbatch. 

The Police Serious Crash Unit is attending this crash involving two vehicles.

The highway was recently reduced to 80km/hour speed limit given the history of crashes on the road.

The Serious Crash Unit has been advised.

Enquiries into the circumstances of the crash are ongoing.
