International migration statistics give the latest outcomes-based measure of migration, which includes estimates of migrants entering or leaving New Zealand.

Key facts

The comparisons between the November 2021 and 2020 months and years use the latest provisional estimates for each period.

The provisional estimates have 95 percent confidence intervals (±) beside them – the wider the interval, the greater the uncertainty about the estimate. However, these intervals reflect the model uncertainty, not the extent of future revisions to provisional data.

Provisional migration estimates are revised each month until they are finalised after 16 months. Migration data transformation has more information about the migration estimates, including the 12/16-month rule and a monthly summary of the number of border movements, the number requiring modelling as migrants or non-migrants, and the history of revisions to migration estimates (see Comparison of provisional and final migration estimates: August 2017–November 2021).
