Police recorded 21 arrests in connection with the party - compared with 18 at last year's party - for minor offences including offensive behaviour, trespass, disorder, unlawfully on property, wilful damage, and theft.
Dunedin acting area tactical response manager Acting Inspector Mel Aitken said 11 people arrested this year were students, with the remaining 10 being Dunedin-based tradesmen.
Two people were taken into custody for detox and would not be charged.
Fourteen people would receive pre-charge warnings, with five likely to be dealt with by the courts.
"For us it was about keeping the peace. We certainly weren't hands-on."
Police operated a one-way door policy from 2pm and the music was turned off at 5.30pm.
"After that it was just a normal Saturday night for Dunedin".
University of Otago vice-chancellor Harlene Hayne, who spent the day on Hyde St, was pleased with how the event went, but said it was too early to speculate on the future of the party.
"In a perfect world, the students who attended the Hyde Street party would have spent Saturday in the library. But given that was never going to happen, I am very pleased with the way that students conducted themselves on the day.
"I am extremely grateful for the support that was provided by OUSA, Red Frogs, the Police, and St John's. That support, coupled with the reduced numbers, made all the difference," she said.
Southern District Health Board medical directorate general manager Sharon Mason said "compared to previous years it went more smoothly".
"There were still some intoxicated students but anecdotally the staff felt compared to previous years there was certainly some improvement."
Thirty-five St John staff and volunteers treated 60 patients from a temporary compound near the keg party.
St John southern region operations manager Doug Third said this year's patients were largely as a result of gross intoxication, a few minor lacerations and one person who fell off a roof and fractured an arm.
"There were people so grossly intoxicated they could not look after their own airways, so those people, around 15 of them, were kept for a couple of hours with a drip in their arm."
Fire Service East Otago assistant area commander Craig Geddes said while the day started off busy, with two early morning couch fires in the student quarter it was a relatively quiet Saturday.
"It was pretty much business as usual, and while it is disappointing to attend any couch fires, they were to be expected, given the event and the number of parties going on. But overall we are very happy."
