Dunedin police were happy to see more students reporting overcrowding to police, but said there was more work to do after about 300 students were found on the top storey of a three-floor flat.
Senior Sergeant Craig Dinnissen said O Week had been quieter and more controlled than Flo-Week, the annual student-organised orientation week for flats, but there was still some work to do around the Sophia Charter.
There had been some overloaded flats, however many tenants had done the responsible thing and called police to help get people out.
"That was good to see," he said.
One flat had an estimated 300 people on the top storey of the three-floor flat, and a separate flat in Warrander St had called police on Wednesday about 11.45pm once they noticed their property becoming overcrowded.
Music was turned off, and people were dispersed safely.
Last Friday, Snr Sgt Dinnissen said the only thing reported overnight from police working during O Week was that there was some "really bad karaoke" coming from about 120 students celebrating in The Bog Irish Bar.
"No issues other than terrible singing, so that’s pretty good."
Usually, Flo Week had more problems than O Week.
Snr Sgt Dinnissen said it was because Flo Week had fewer events planned by agencies.
"You’ve got an OUSA, the University, Red Frogs, Are You OK?, and the council all helping out during O Week.
"Flo Week is the one that we want to try and curtail in and ... drag it in a bit finer."
On February 14 a Flo Week party at the corner of Castle and Howe Sts resulted in three people getting hit in the head by thrown objects.
They were all taken to and treated at Dunedin Hospital.
On February 11, a young man was found by University of Otago Campus Watch staff lying on the ground with critical injuries after falling 10m from a building — ending up in an induced coma.
He was a student at another tertiary institution in New Zealand.
Senior Constable John Woodhouse, Dunedin’s campus constable, said last week glass bottles being thrown from within mosh pits continued to be a "bane" for police.
It was hard to identify the perpetrators in those incidents, he said.
Flo Week had been a phenomenon for at least the past decade but was "certainly getting bigger", Snr Const Woodhouse said.
