A nose-to-tail crash gummed up the southern motorway traffic into Dunedin and slowed traffic to a crawl this morning.

Traffic into the city was being diverted through Kaikorai Valley Road following the crash south of Lookout Point.

Police were notified at 7.50am that a car and ute had collided on the Dunedin Southern Motorway, between Main South Road on-ramp and Caversham Valley Road.

One person was being checked over by ambulance staff, a police spokeswoman said.

Contractors have been requested to assist with clean-up of debris on the road.
