Dunedin police say this week's student antics on Saint Patrick's Day were some of the worst they've seen with drinking from 4am, couch-burning and several people hit in the head by flying bottles.
Hundreds of people also travelled to the city to join students partying on the streets.
Sophia Crestani died after being crushed on a staircase pile-up at a party hosted in a student flat known as The Manor in October 2019.
Her father, Bede Crestani told RNZ's Checkpoint he was horrified to hear of the incidents in Dunedin on St Patrick's Day.
"Also, seeing students on roofs, it just feels like it's a bell curve and at some point someone's going to die again."
A culture change from the students themselves would have the best long-term result, he said.
"Parents have a big role to play, we constantly hear of parents saying 'I did it in my day, you go ahead and do it, it's all a bit of a laugh', and the latest students do more.
"Unfortunately we visit our daughter at a grave, so we know it's not a possibility, it has happened and it's likely."
Crestani said Otago University was the best in the country in terms of academic achievement but the drinking culture needed to change.
He said government agency support was needed to urgently review safety and whether Otago University had been let down by out-of-towners and non-students causing problems.
Liquor stores and supermarkets also needed to "step up and see the harm that their products cause".
Otago University's director of student services Claire Gallop said the issue of "interlopers" in North Dunedin on St Patrick's day continued to cause concern.
She said the university was told a large number of students from other tertiary institutions planned to travel to the southern city on Monday.
It was "disappointing" the actions of a few reflect poorly on all Otago University students.
While the university code of conduct could apply to Otago University students, it had no jurisdiction over those not enrolled there.
