From 2024, the “NZ European” and “Other” ethnic groups are merged into the “European or Other” group.

Figure.nz have collected annual datasets since 2016 and appended them into one document.

This data shows the immunisation coverage for children who turned the milestone age during the 12 month reporting period between June 2016 to 2024, and who have completed their age appropriate immunisations.

From 2005 to 2023 immunisation coverage was measured using data from New Zealand’s National Immunisation Register (NIR). 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.
