Data calculation/treatment
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.
Please note the ethnic group is calculated based on the prioritised ethnicity method.

Inclusions
Coverage figures include Pneumococcal vaccine.
Changes to data collection/processing
From 1 April 2024 the “opt-offs” category has been removed as the AIR only reports on “active individuals”.
From 1 January 2024 ethnicity coverage of “NZ European” and “Other” ethnic groups merged and created the “European or Other” group.

About this dataset
This data shows the immunisation coverage for children who turned the milestone age during the 12 month reporting period ending June 2025, and who have completed their age appropriate immunisations.
Method of collection/Data provider
At the end of 2023, the NIR was retired and was replaced with the new Aotearoa Immunisation Register (AIR). The AIR captures a greater number of eligible tamariki compared to the NIR, which means a drop in coverage is expected.
