Teams from each college, as well as a side made up of Dunedin resident students, competed for supremacy in touch rugby, soccer, volleyball and rugby.
Each team was ably supported from the sidelines with team mascots and students decked out in their college colours - some sporting face paint - cheering on their teams.
University vice-chancellor Harlene Hayne, who was at sports day along with other senior university staff members, said the event was a great great opportunity for students to make friends.
The day also served as a way to promote healthy lifestyles to students and show off the sporting opportunities open to them at the university, Prof Hayne said.
''We have been spending a lot of time during orientation telling both parents and incoming students about all the opportunities both at Unipol and through Clubs and Socs.''
Students had the opportunity to see what clubs and societies were on offer at Clubs Day tomorrow.
Otago University recreation services manager Daniel Porter reckoned somewhere between 2000 and 2500 students turned up to the sports day, with the turnout boosted by the perfect weather.
