Police are happy with the behaviour at this year's Hyde St party in Dunedin - so far.
Security has been tightened up and there were just three arrests as of 6pm on Saturday night.
But it was still the usual costume extravaganza, with thousands dressing up - many as David Bain and Shania Twain.
The small street of 30 flats hosts one of the largest events on the University of Otago student calendar.
In the past the party has attracted trouble. At the peak of its popularity in 2012, safety concerns were raised when a roof collapsed under the weight of too many partygoers, injuring more than 80 revellers - many of them drunken students.
Now roofs are off-limits to the crowd, which has been downsized to just over 3500 revellers.
And extra measures such as tighter security and food have been put in place.
"They've put up all the fencing so everyone's been up since five o'clock this morning getting everything set, and the road's closed off til midday tomorrow," University of Otago Students' Association president Caitlin Barlow-Groome told Newshub.
The party's still attracting the attention of partygoers - just not so much the controversy it was infamous for.
