The data were collected across New Zealand by Statistics New Zealand1 as part of the Census of Population and Dwellings. The purpose of the Census is to collect demographic and social statistics, which can be used by Government, business and community organisations for planning and other decision making.
This indicator is usually updated every five years after the results of each Census are published. There census that was supposed to occur in 2011 was delayed until 2013 due to the Canterbury earthquakes. The next Census is due in 2018.
Census information on the population growth is easily available for the period 1991-2013 from Statistics New Zealand. The period between the 2006 and 2013 census was 7 years instead of the usual 5 years.
The Population Census is a self-administered hand-delivered questionnaire carried out every five years. Statistics New Zealand tries to cover all people in New Zealand on Census night. Data are entered into a national database and rounded to ensure anonymity. Data are summarised into various levels including national, regional and territorial authority.
