Sergeant Dion Phair said police received multiple calls from Stafford St residents complaining about noise and people climbing on the fire escapes. It was also reported someone had thrown a beer bottle at police, he said.
''It was a bit feral. I think they had a flat red-card where one of the 20 tenants pulls out a red card, and everyone else goes on the booze for the day. It's a pretty common practice in student flats.''
The party started about 7am yesterday but was shut down by police about 4pm when four earlier warnings went unheeded.
No-one was charged, but details of the incident had been sent to the University of Otago proctor, he said.
