Some students in Dunedin are self-isolating and the University of Otago has issued an alert aimed at tracking down any recent arrivals with connections to the latest Auckland Covid-19 cluster.
Auckland's active cluster, which emerged on February 14, expanded to 11 community cases on Tuesday.
It now includes Papatoetoe High School pupils and a sibling of a pupil who works at Kmart and recently attended the high school.
The university said yesterday it was calling students who arrived from South Auckland in the past 14 days, asking about their recent movements and general health status.
