An 18-year-old University of Otago student has been admitted to Dunedin Hospital in a serious condition with meningococcal disease.
A university spokeswoman said the male student was a resident at Studholme College in Dunedin.
"Information about symptoms of the disease has been provided to the college and support offered to residents, including the offer of antibiotics for other students at the college," she said.
College staff were in touch with the student's family and were offering them support.
"Student Health and the university is closely monitoring this situation, and will provide further information as and if necessary," the spokeswoman said.
