The parents of an Otago University student killed at an overloaded party have launched a safety campaign in her honour.
Sophia Crestani was killed after being caught in a stairwell pileup at a flat called The Manor in October 2019.
Almost a year on, the 19-year-old's parents have launched the Sophia Charter which marks a commitment by key agencies to enhance the wellbeing and safety of Dunedin students.
NZ Police Otago area prevention manager Wil Black said it's something positive to come out of Crestani's death.
"It's a tragedy, there's no two ways about it," he said.
"For those of us who are parents, most of us cannot even imagine what that family has gone through, and is going through but through their strength and through their tireless work this will become Sophia's legacy."
Black said the charter will "definitely be a catalyst for change".
"I think the students sense that because when all is said and done, they come to Dunedin to learn to have fun it's a vibrant city and people love coming here. It's our collective responsibility as a wider community to ensure students remain safe while they are here."
Now they are working to ensure large parties and gatherings are controlled and students feel safe.
