Health authorities continue to identify people who may be affected with measles as confirmed cases in Taupo and Turangi remain at 10.
Bay of Plenty medical officer of health Phil Shoemack is urging parents to make sure their children's vaccinations are up to date to prevent the spread of virus.
"With families travelling around New Zealand and overseas these summer holidays, it's important to ensure that you and your children are up to date with immunisations in general and MMR [measles, mumps and rubella vaccine] in particular.
"Measles immunisation provides effective protection and the vaccine is completely free for children and adults. MMR is given in two doses, normally at 15 months and 4 years of age," Dr Shoemack said.
People born before 1969 were likely to be immune because measles used to be quite common but those born from 1969 onwards who were unsure of their immunity should check with their doctor.
