Students at the University of Otago are being offered free booster shots after an outbreak of mumps was confirmed in Dunedin.
About 10 cases of the contagious illness have been confirmed at the university.
The university's student health team is now offering free measles, mumps and rubella (MMR) booster shots to students who have not had two MMR vaccinations since 1990, or are unsure of their vaccination history.
Clinics are being held today and tomorrow.
Pro-vice-chancellor of health sciences Professor Peter Crampton, the convener of the university's pandemic planning group, said the group was ''closely monitoring the evolving situation''.
