Everything about the annual event, including bands, comedy and hypnotist acts, a sports day and parents' orientation, was "supersized", he said.
"Everything was massive. To make it work we had hundreds of volunteers and staff."
Mr Edgar said Forsyth Barr Stadium staff, technical personnel, Red Frogs, the Are You OK? team and OUSA staff and volunteers worked together throughout the event. In particular he acknowlegded the work of OUSA event management Dan Hendra and Kitty Brown.
The OUSA also thanked the Dunedin City Council, University of Otago, and all Dunedin citizens.
"We are proud of creating pro-social events that contribute to a better Dunedin.
"The police do a good job but can be a cagey lot sometimes, so it was good to see them talk about how well organised our events were," Mr Edgar said.
For the first time, Orientation concerts were held at the Forsyth Barr Stadium and open to the public. Headline act Shapeshifter was a sell-out on Saturday night, attracting 4500 revellers.
