St John Ambulance has confirmed that some of its Auckland staff have been quarantined because of a case of measles within the organisation.
It's not known how the employee contracted the disease, but the person is not sick enough to be admitted to hospital.
St John says it is testing a small group of employees for the disease and has distributed pamphlets to staff encouraging them to get vaccinated.
The organisation says it's taking a proactive approach to the measles outbreak in Auckland, including the standard procedure of cleaning all ambulances that have transported patients who may be carrying an infectious disease.
