Police are investigating a report of a sexual attack at Lincoln University's Halls of Residence.
The incident happened on Farm Rd on Tuesday night.
Detective Senior Sergeant Scott Anderson said a woman was sexually assaulted by a man known to her.
Both the victim and alleged offender are yet to be spoken to by police, he said.
"This is an isolated incident and there is no concern to the wider public," he said.
A Lincoln University spokesman said it took the allegation "very seriously".
"The safety and wellbeing of our staff and students is a priority at all times," he said.
He said it was not appropriate to make further comment until police investigations were complete.
Detective Senior Sergeant Anderson said there was no link to a sexual attack where a 48-year-old woman was assaulted near the bend of West Belt and North Belt in Lincoln after she left the Selwyn Sounds concert on March 4 at 6.30pm.
Star.kiwi reported in April that leads in that case had dried up and police were appealing for anyone who had not yet come forward to do so.
The 19-year-old disappeared without her wallet or mobile phone.
