A woman is being cut from her vehicle after a three car-crash at Bulls.
The crash initially blocked State Highway 1 south of the township, on the bridge near Tangimoana Rd, but the northbound lane has now reopened. The southbound lane is expected to open soon.
A police spokeswoman said the woman, whose car crashed into a barrier on the bridge, was the only person injured in the crash.
She has suffered serious injuries and will be taken to hospital by St John Ambulance.
Police were called to the crash at 10.52am.
