A car towing a trailer rolled on Three Mile Hill Rd near Dunedin yesterday evening, partly blocking the road.
One person was taken to hospital, police said.
A Hato Hone St John spokeswoman said last night the patient was in a moderate condition.
The crash in North Taieri happened about 6.30pm.
A police spokeswoman said the car was on its side and the trailer had become detached.
Fire and Emergency NZ said crews from Roslyn, Mosgiel and Lookout Point were sent to the scene. — APL
