Annual population growth rate in New Zealand

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.
