As part of the fifth annual Jesus Week, volunteers from the University of Otago and Otago Polytechnic, armed with 40 empty rubbish bags and wearing rubber gloves, headed to the student area on a mission.
Discarded beer bottles and the remnants of last night's takeaways were no match for the eight street cleaning volunteers intent on providing "Christian service" to their community, University chaplain the Rev Greg Hughson said.
An opening service and the clean-up marked the beginning of Jesus Week, during which members of the Otago Combined Christian Groups celebrate their faith by holding a variety of events, he said.
Beginning in Castle St, the volunteers filled all of the 40-litre bags, which were supplied by the Dunedin City Council, in just under two hours.
Mr Hughson said students had expressed their gratitude for the clean-up.
