A word of caution about Census data. Stats NZ does not adjust Census data for undercount, so it only provides a partial picture of 's population. Census data is best used for understanding the composition of 's population. To understand the size of 's population, we recommend using Stats NZ's Estimated Resident Population (ERP) series, presented in the Population section, which is a more comprehensive and reliable measure. The ERP accounts for individuals that were missed in the Census by using secondary sources such as administrative data and a post-Census survey.
