International migration: January 2021
– Infoshare tables

15 March 2021

Key facts

The comparisons between the January 2021
and 2020 months and years use the latest provisional estimates for each

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.


Year ended January 2021 (compared with year
ended January 2020) provisional estimates were:

  • migrant arrivals – 68,800 (± 700), down
    60.0 percent
  • migrant departures – 35,700 (± 400), down
    62.3 percent
  • annual net migration gain – 33,200 (± 800),
    down from 77,800 (± 100).

Annual net migration of New Zealand citizens
has exceeded that of non-New Zealand citizens for the first time since
citizenship data started in the late 1970s.
