National and DHB immunisation data

Immunisation coverage for New Zealand children at two years of age is 85.4% percent for the three-month period ending 30 June 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 June 2021 and who have completed their age appropriate immunisations.

Please note for the three-month and 12-month reports ending 30 June 2021 only, the data tables shown below are based on more recent data than the ‘National and district health board data spreadsheets’ linked below which include a breakdown by district health board. 

A data quality issue also 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 coverage rates as a result.
