The party resulted in eight arrests and 10 people being taken to hospital, but provided few headaches for emergency services.
Senior Sergeant Craig Brown said another three Dunedin men - two 18-year-olds and a 19-year-old - were arrested after setting fire to bags of rubbish piled up on Hyde St at 5.30am yesterday.
All three men would appear in the Dunedin District Court tomorrow, he said.
Otherwise, the crowd of about 3600 people at the street party behaved well and police were generally pleased, Otago Coastal area response manager Senior Sergeant Dave Scott said.
He attributed the success to work Campus Watch and police carried out before the party to ensure couches, chairs and other material were moved from front yards.
No-one was allowed on roofs and the street was fenced off, with security guards manning the gates.
The Otago University Students' Association promoted the event as glass-free to reduce the chance of injury to students.
"These pre-event measures along with pre-ticket sales of limited numbers helped make the event safer for all,'' he said.
"Eight arrests were made for minor offending, largely made up of people repeatedly trying to illegally enter the event. Those arrested were both students and non-students.''
Police were assisted by Maori Wardens, the Fire Service, the University of Otago, OUSA, the Dunedin City Council, ACC, Dunedin Public Hospital, Student Health, St John, landlords, tenants and nearby businesses in planning and operating the event.
Worksafe was also involved, he said.
Some residents in the street began drinking early in the day.
The party began at 9am, a one-way door policy came into effect at 1pm and crowds began to dwindle by about 4.30pm.
The event finished at 6pm.
OUSA president Laura Harris said the event was "extremely successful''.
"OUSA is pleased with how everything has panned out and I have truly enjoyed being part of an event with such high spirits and creative costumes.''
OUSA took over planning the party after a roof collapse at the 2012 event.
The number of arrests was the lowest since the student body became involved, Miss Harris said.
St John spokesman Robbie Walker said St John treated 52 people at the event for a variety of issues, including intoxication.
Ten people were taken to Dunedin Hospital with "mostly minor injuries'', he said.
Last year, an ambulance was attacked by a drunken student and 12 people were arrested.
