This graph shows childhood immunisation coverage rates in New Zealand at 24 months of age, by ethnic group, between 2009 and 2022. The percentage of two-year-olds who had received the recommended immunisations for their age rose and then fell. Low immunisation coverage (below 95% of the population fully immunised) means there is a much higher chance of an outbreak of an infectious disease.  

In 2009, 83% of all two-year-olds were fully immunised for their age, well below the government’s 95% target. The figure had improved by 2014 to a high of 93%. It remained above 90% until 2020, after which it fell sharply. This probably reflects the effect of the COVID-19 pandemic. By 2022, the percentage of fully immunised two-year-olds was only 83%. The trend was even more apparent for Māori children: 77% were fully immunised in 2009, 92% in the mid-2010s, and only 68% in 2022.

* ‘Other’ means children enrolled on the National Immunisation Register of any ethnicity except Māori, Pacific, Asian or New Zealand European. Includes European, African, Middle Eastern, Latin American/Hispanic.
