New Zealand's population is estimated to increase by one person every 5 minutes and 42 seconds.

This is based on the estimated resident population at 31 December 2019 and the following forecasts: 

• one birth every 8 minutes and 43 seconds 
• one death every 17 minutes and 9 seconds 
• a net migration gain of one New Zealand resident every 8 minutes and 25 seconds. 

The forecasts are based on recent trends and do not necessarily reflect actual population change.

The population clock is based on the estimated resident population and does not correspond to the census usually resident population count or census night population count.

The estimated resident population is derived from the 2013 Census usually resident population count, with adjustments for people missed or counted more than once by the census (net census undercount), residents temporarily overseas on census night, and population change since census night.
