Local health authorities are urging parents to ensure their children get their measles vaccine as supply numbers improve.
With 33 cases of measles in the Bay of Plenty and Lakes District Health Board areas since the beginning of last month, and 10 confirmed this month, the risk remains high.
Further vaccine supply has improved lately for the MMR (measles, mumps and rubella) that protects against measles. It is free for everyone.
Medical officer of health for Toi Te Ora Public Health Dr Jim Miller said the vaccine supply was sufficient for them to focus on having children vaccinated at 15 months and four years.
Stocks are also good enough that infants travelling overseas and to Auckland can have their vaccine earlier, Miller said.
