"Mental health, depression and anxiety are huge issues for university students," Higgins said.
She said students should also be looking to help out their peers.
"It's important to be prepared to listen as well."
University of Canterbury spokesman Phil Barclay said the university will be bringing in extra counselling services.
"We have a range of support available, we do have health services on campus and we are making sure we have sufficient resource available should that be necessary."
Acting vice-chancellor Dr Hamish Cochrane said the university is "very mindful it has occurred in the period leading up to exams and end-of-year assessments".
University staff have been assisting students at the hall, and all students and staff have been advised of the support available.
The university offers free counselling services to students.
