A woman has been arrested in relation to threats to University of Otago graduation ceremonies last week.
The university was forced to postpone several ceremonies and parades last week, and on Monday it announced this week's four graduation events would also be called off.
The decision was made following a "security threat".
Police launched an investigation into the incident and on Friday, Southern District Commander Superintendent Paul Basham confirmed they had made an arrest.
"A 22-year-old woman has been charged with threatening harm to people or property. She is due to appear in Auckland District Court today," he said.
"We know this result will provide a sense of relief to both the University of Otago and our wider Dunedin community."
Basham said he wanted to acknowledge Otago University's Vice Chancellor Harlene Hayne and her team for their resilience, along with the "tireless efforts" of the investigation team.
Hayne said in a statement that she was "relieved" there had been an arrest.
"I am extremely disappointed that these actions resulted in graduation ceremonies for more than 2500 graduands and their whānau being postponed.
"Unfortunately, it is too late to change arrangements for tomorrow's graduations which are postponed; however, we have many on-campus celebrations planned and I hope graduands and their supporters will join us to celebrate their academic achievements."
Many graduating students were left disappointed when their ceremonies were cancelled.
"It's pretty annoying to have the whānau down and have to disappoint but you know, better to be safe than sorry," student Ben Shine told RNZ.
Hayne said she understood students would be gutted after a particularly difficult year.
"In the wake of COVID-19, our students have overcome huge obstacles to stay on track and complete their degrees this year. Moreover, many of our students and their whānau have made significant sacrifices to travel to Dunedin so they could be a part of these very special celebrations," she said.
Students found other ways to celebrate including hanging out on campus and gathering at flats, Jack Manning, the President of the Otago University Student Association, told MagicTalk on Tuesday.
"[There] are still hundreds of students out on campus with their families, still taking photos, still wearing their regalias, still carrying their flowers, still celebrating basically," he said.
"[They're] still finding a good time to actually acknowledge their accomplishment that they have been working towards for years, even if it is not exactly what they had in mind.
"We have seen makeshift graduations getting put together by students on Castle St. We have seen people finding really creative ways to still mark the day."
