Population - Components of population change by year ended June 1961–2019
Estimated de facto population: De facto population estimates include all people present in New Zealand and counted by the census (census night population count).
Estimated resident population: The estimated resident population is based on the census usually resident population count, updated for residents missed or counted more than once by the census (net census undercount); and births, deaths, and net migration between census night and the date of the estimate.
Natural increase: For the estimated de facto population, excess of registered births over registered deaths. For the estimated resident population, excess of estimated births over estimated deaths (both by date of occurrence).
Net migration: For the estimated de facto population, excess of total arrivals over total departures. Excludes armed forces before 1987.
For the estimated resident population, excess of permanent and long-term arrivals over permanent and long-term departures.
Limitations of the data
The population estimates are subject to revision to fully incorporate 2018 Census and census coverage results later in 2020, as well as revisions to international migration estimates.
Changes to data collection/processing
Estimates from 1991 onwards are not strictly comparable with estimates for earlier years, due to conceptual differences.
