Auckland City Hospital has begun vaccinating some frontline staff members against measles.
The Auckland region is in the fifth month of a measles outbreak, with most cases occurring in central Auckland.
The hospital's clinical adviser for infection control, Sally Roberts, says 85% of staff are immune and others who hadn't been vaccinated are usually picked up by pre-employment screening.
But Dr Roberts says clinics have been set up at the hospital this week and last week for any unvaccinated staff, especially those working in the adults or children's emergency department and general medicine.
