A child was among the injured in a serious crash in East Auckland this morning.
Police have just reopened the Whitford-Maraetai Rd five hours after a car crash that hurt four people, including one who was critically injured.
Traffic heading into Auckland, including morning commuters and students on school buses, faced huge detours travelling through Clevedon because of the road closure.
A police spokesman said two cars collided near the intersection of Trig Rd about 6.30am and four people were injured.
One person had to be freed from a vehicle. A young child was one of those hurt in the smash.
A police spokeswoman said an off-duty ambulance officer who came across the smash tended to the injured.
The person trapped was in a critical condition and another was thought to be in a serious condition. Police say the child suffered moderate injuries.
St John Ambulance said three people were taken to Middlemore Hospital.
