National and DHB immunisation data

Immunisation coverage for New Zealand children at 24 months of age is 83.4% percent for the three-month period ending 30 September 2021.

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), 54 months (four and a half 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 30 September 2021 and who have completed their age-appropriate immunisations.

Please note a data quality issue affected how a small number of immunisation events were recorded following the October 2020 Schedule change. A fix has since been applied and these are now reporting correctly, however you may see slight variations in the previous Q2 and Q3 20/21 coverage rates as a result.
