Two people were injured in a three-car crash on State Highway 1, south of East Taieri yesterday.
Upon arrival they discovered one person stuck in their car and used rescue equipment to extract them.
A police spokeswoman said emergency services were called about 9.30am to where three cars had collided in a nose-to-tail incident between Riccarton Rd and Gladfield Rd. The northbound lane was blocked and traffic was diverted down Riccarton Rd East.
A Fire and Emergency New Zealand spokesman said crews from Lookout Point and Mosgiel were at the scene.
The process was completed quickly and within about 15 minutes drivers of both vehicles were in the care of St John.
St John said two ambulances responded. Two people were treated and transported to Dunedin Hospital in a moderate condition.
