Students at the University of Auckland and two big schools have tested positive for Covid-19.
An email to staff from the University's vice-chancellor, Dawn Freshwater, said the student - a resident at Whitaker Block - attended classes on Monday and Tuesday this week.
The student then travelled to Wellington to be with family before testing positive, Freshwater said.
"The university is working closely with the relevant health agencies on this situation, and is following their protocols, including for contact-tracing, to support our student and to protect the wider university community," Freshwater said.
