A police spokeswoman said police were called to the crash about 3pm today.
She said the road was blocked for a short time but had since cleared.
A Hato Hone St John spokesman said two ambulances responded and two people were taken to Dunedin Hospital, one in a moderate condition, the other in a minor condition.
An NZ Transport Agency Waka Kotahi spokesman said contractors were required to clean up debris and oil spilled on the road.
He said one lane was kept open so no road closure was required.
Traffic was crawling and could be seen backed up to the Oval.
