The Auckland University of Technology says a third student has tested positive for Covid-19.
The three infected students have been moved into managed isolation, and the university is working with health authorities to identify close contacts, AUT said in a statement this afternoon.
Those identified will receive an email from Auckland Regional Public Health Service (ARPHS) on what to do.
AUT also released information about the person's movements on Monday and Tuesday, including a library space and lectures at the university's north and city campuses.
