Introduction to population estimates

The estimated resident population of an area in New Zealand is an estimate of all people who usually live in that area at a given date. Visitors from elsewhere in New Zealand or from overseas are excluded. 

The estimated resident population at 30 June 2013–16 is based on the 2013 census usually resident population count, updated for:

  • net census undercount (based on the 2013 Post-enumeration Survey)
  • residents temporarily overseas on census night
  • births, deaths, and net migration between census night and the date of the estimate
  • reconciliation with demographic estimates at ages 0–9 years.

The estimated resident population is not directly comparable with the census usually resident population count because of these adjustments.

We have also revised population estimates at 30 June 2007–12 following results from the 2013 Census.

NZ.Stat tables

The tables below provide population estimates with final figures for 2016. For enquiries about the subnational areas that feature in these tables, contact info@stats.govt.nz.

Information about rounding

Within the tables, individual figures may not sum to stated totals due to rounding.

The rounding of figures is determined by the total population size of the geographic area. The rounding rules that have been applied are shown below.

Total population size of geographic area Rounding of five-year age group cells Rounding of broad age group and total (all ages) cells
Less than 2,000 5 10
2,000 to 9,999 10 10
10,000 to 19,999 10 50
20,000 or more 10 100

For example, if a geographic area has a population of 15,000 then five-year age group cells will be rounded to the nearest 10, and broad age group and total (all ages) cells will be rounded to the nearest 50.

Limitations of subnational population estimates

Population estimates give the best available measure of the size and age-sex structure of the population usually living in an area. However, uncertainty is inherent in the estimation process. We produce population estimates using a component methodology, where the components of population change (births, deaths, and net migration) are used to update a base population. There is some uncertainty associated with component data, particularly the estimation of net migration (international and internal migration combined) for subnational areas. Generally, the uncertainty associated with population estimates increases as the estimates move further away from the base or starting point (in this case 30 June 2013). Uncertainty also increases as population estimates are broken down by age, sex, and geographic area.

It is not possible to ascertain the accuracy of current population estimates as no independent authoritative measure of the resident population exists. Furthermore, no data source perfectly measures changes in the resident population, or even movements of the resident population within New Zealand.

Since 2006, we have implemented a number of changes to our estimation methods aimed at improving the accuracy of population estimates. These changes have included the use of various administrative data sources and refined methods for using these data sources. Collectively, they provide confidence about the general robustness of population estimates.

The periodic Census of Population and Dwellings remains the cornerstone of population statistics in New Zealand. Following the 2013 Census, we have revised all population estimates at 30 June 2007–13.
