A 10th case of measles has been confirmed in Northland with six other suspected cases being investigated.
Northland District Health Board is asking parents to ensure their children are vaccinated before the school holidays arrive - a time when families often travel, have visitors or attend more public places.
Public Health Nurses are offering the MMR (measles, mumps and rubella) vaccination to children and staff at the schools they are currently visiting with the Boostrix immunisation (diphtheria, tetanus and whooping cough). Parents are being given a consent form to return to school.
''We know that the MMR coverage of our 11-12-year-olds is around 75 percent, and testing for measles immunity suggests that one in five people in Northland aged 13 and 29 are not immune to measles,'' Medical Officer of Health Dr Catherine Jackson said.
''With school holidays coming up it would be a good idea for parents to make an appointment with their general practice for their teenage children to be vaccinated.''
