Arana College and the University of Otago say they are working closely with health authorities after a contagious measles patient spent time on campus last weekend.
The patient, who visited Wanaka, Queenstown, Winton and multiple locations in Dunedin before being diagnosed with the highly infectious disease, stayed at Arana College for two nights and went to a concert at the Union Hall.
''Staff are taking a watching brief on all residents and are preparing in the chance there is a confirmed case of measles,'' college senior warden Jamie Gilbertson said.
''We are now working under the guidance of the medical officer of health and in collaboration with Student Health Services.''
All college residents and their families had been told of the situation.
Student Health Services acting director Margaret Perley said demand for measles vaccine had been high since the semester began, and there were limited supplies available to Student Health.
''Following yesterday's notification from Public Health [South], we once again communicated with staff and students via text, email and social media,'' Dr Perley said.
''There are currently no cases of measles among students or staff at the University of Otago.''
Earlier this year Student Health organised additional vaccine clinics for both measles and meningitis to meet demand.
One more measles case was confirmed in Queenstown yesterday. In total 23 residents and one visitor from Auckland have been diagnosed with the disease in the town.
The Ministry of Health yesterday announced Government drug-buying agency Pharmac had sourced an extra 100,000 doses of measles vaccine.
Director-general of health Ashley Bloomfield said 175,000 doses of the MMR vaccine had been given out this year, compared with 94,000 during the same period last year.
''An additional 52,000 doses of MMR vaccine arrived in New Zealand this week, and processes are being fast-tracked to ensure additional stock is secured and distributed as quickly as possible,'' Dr Bloomfield said.
Children aged between 15 months and 4 years old are the priority for vaccination.
