National and DHB immunisation data

Immunisation coverage for New Zealand children at two years of age is 92 percent for the three-month period ending 31 March 2020.

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 or 12-month reporting period ending 31 March 2020 and who have completed their age appropriate immunisations.
