The crash was reported at approximately 2:30 PM. The vehicle rolled, scattering grain across the road and blocking both southbound lanes.

Casualties and Medical Care
One individual was assessed by ambulance crews at the scene and transported to Middlemore Hospital in a serious condition. A second patient was present but declined a medical assessment from the staff.
