National and DHB immunisation data

Immunisation coverage for New Zealand children at eight months of age is 93 percent for the three-month period ending 31 March 2015.

Immunisation coverage is measured at ‘milestone ages’ using National Immunisation Register (NIR) data. The milestone ages are six months, eight months, 12 months (one year), 18 months, 24 months (two years) and five years of age.

The following tables show the immunisation coverage for children who turned the milestone age during a three-month and 12-month reporting period ending March 2015, and who have completed their age-appropriate immunisations.
