Data Quality
Using this data
You can use this data confidently. Stats NZ rated it as high quality. For more information, read about response rates below.
Stats NZ gives data an overall rating based on sources and coverage, consistency, and data quality.
Why am I seeing this?
This data is from the Census. The past two censuses had relatively low response rates, particularly for some areas of New Zealand and groups of people.
Where information was missing or unreadable, Stats NZ attempted to use data from a range of places such as previous censuses or administrative data that is collected by other government agencies. If that isn't available, Stats NZ use statistical models to predict what the missing data would have been. This is called imputation.
Things to be aware of
The language classification with the highest imputation rate is the Central Eastern Malayo-Polynesian language group. This category includes Te Reo Māori and most of the languages spoken in the Pacific.

About this dataset
The New Zealand Census of Population and Dwellings is the official count of how many people and dwellings there are in New Zealand. It provides a snapshot of our society at a point in time and helps to tell the story of its social and economic change. The 2023 Census, held on Tuesday 7 March, was the 35th New Zealand Census of Population and Dwellings. The first official census was run in 1851, and since 1877 there has been a census every five years, with only four exceptions.
Purpose of collection
Census information is used by government agencies, local authorities, businesses, community organisations, and the public for developing and implementing new policies, research, planning, and decision-making. It helps us make decisions about how to best use public funding, especially in areas of health, education, housing, and transport.
The census is also the primary source of information used for deciding the number of general and Māori electorates, along with data from the corresponding Māori Electoral Option.
