The future of Dunedin's Hyde Street Keg Party looks to be in safe hands, with organisers touting Saturday's event as a huge success.

About 3600 students descended on the annual street party, with festivities going off without a hitch.

Otago University Students' Assocation (OUSA) president Hugh Baird says there was a huge emphasis put on safety this year.

"We had about 400 staff working, and it just means that we're able to take care of students if they do have any necessary circumstances."

Police arrested 10 people at the event, mainly for trespassing and disorderly behaviour. This is up from the eight arrested in 2016, but police aren't too concerned.

"The general behaviour was good and it was a positive time for those attending," said Insp Shona Low.

"It was a well-run event, and OUSA should be commended for the effort it put in to organising the party."

Mr Baird says it shows the event is here to stay.

"There'd be a huge uproar if you were cancel the event. Hyde St is like Christmas for Scarfies. It's an incredibly important event, and it's something we don't want to see dropped off the calendar.

"One of things we talked about with students this year was making sure they're custodians of the party. It seems like they've taken that on board."

OUSA took over running the annual party in 2013, after what the police called "unruly scenes" at previous years' events, including a roof collapse in 2012.

"Furniture fires, roof collapses and abuse of emergency workers have all been issues in the past," said Insp Low.

In 2012 there were 15 arrests, and in 2011, 25.

Dunedin Mayor Dave Cull attended the event, and applauded the event's organisers.

"I think it's extraordinarily well-organised and it's been getting better every year in terms of organisation, safety measures, support, and all that kind of thing. Fantastic," he told Newshub.
