Notes
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.
Changes to data collection/processing
Estimates from 1991 onwards are not strictly comparable with estimates for earlier years, due to conceptual differences.
