Roads in Tikipunga are now clear after the removal of a car that was flipped on its roof.
A motorist, who did not want to be named, said he heard a bang and looked to his left where he saw the car on its roof on Kiripaka Rd in Tikipunga shortly before 10am.
He said a large number of people stopped to help an elderly man and woman who were in the vehicle.
A St John spokeswoman said paramedics transported a patient in moderate condition to Whangārei Hospital.
Police had asked motorists to avoid the area while they removed the vehicle but a spokesman said the road is now clear.
