Annual migration

Provisional estimates for the August 2024 year compared with the August 2023 year were:

• migrant arrivals: 188,100 (± 1,100), down 17 percent
• migrant departures: 134,300 (± 1,000), up 37 percent
• annual net migration: gain of 53,800 (± 1,500), compared with a net gain of 127,700 (± 300).

The 134,300 migrant departures in the August 2024 year are, provisionally, the highest on record for an annual period.

Annual migrant arrivals provisionally peaked at 236,200 in the year ended October 2023.

Annual net migration provisionally peaked in the year ended October 2023, with a gain of 136,400.

The long-term average for August years (2002 to 2019) before COVID-19 is 119,900 migrant arrivals, 91,700 migrant departures, and a net migration gain of 28,200.

Migrants are people changing their country of residence, regardless of their country of citizenship or visa status. A 12-month threshold is used to classify migrants from non-migrants, aligned with international guidelines on measuring migration.

Annual migration by citizenship

The provisional net migration gain of 53,800 in the August 2024 year was made up of a net gain of 109,900 non-New Zealand citizens and a net migration loss of 56,100 New Zealand citizens.

For migrant arrivals in the August 2024 year, citizens of India were the largest group, with 37,000 (± 300) arrivals. The next largest groups were citizens of:

• New Zealand: 25,100 (± 300)
• China: 21,800 (± 300)
• Philippines: 21,300 (± 100)
• Fiji: 7,200 (± 100)
• Sri Lanka: 6,400 (± 100)
• South Africa: 5,900 (± 100)
• United Kingdom: 5,700 (± 100)
• Australia: 5,100 (± 200).

For migrant departures in the August 2024 year, citizens of New Zealand were the largest group, with 81,200 (± 800) departures. The next largest groups were citizens of:

• China: 7,100 (± 100)
• United Kingdom: 5,400 (± 100)
• Australia: 5,000 (± 200)
• India: 4,300 (± 200)
• United States: 3,500 (± 100).

Citizens of India, Philippines, and China drove net migration gains in the August 2024 year. Country of citizenship is the nationality of passport used to arrive in or depart from New Zealand and is not necessarily the country of previous or next residence.

For non-New Zealand citizens, the net migration gain of 109,900 in the August 2024 year compares with a net migration gain of 166,300 in the August 2023 year. The long-term average for August years (2002 to 2019) is a net migration gain of 47,800 a year.

The August 2024 year provisionally saw two annual records for New Zealand citizens:

• 81,200 migrant departures, exceeding the previous record (before 2024) of 72,400 in the February 2012 year
• net migration loss of 56,100, exceeding the previous record (before 2023 and 2024) of 44,400 in the February 2012 year.

For New Zealand citizens, there was an average annual net migration loss of 26,600 in the August years (2002 to 2013) and net migration loss of 5,400 in the August years (2014 to 2019).

Monthly migration

Provisional estimates for August 2024 compared with August 2023 were:

• migrant arrivals: 13,400 (± 600), down 38 percent
• migrant departures: 10,500 (± 600), up 43 percent
• monthly net migration: gain of 3,000 (± 900), compared with a net gain of 14,200 (± 200).

Provisional migration estimates are revised each month until they are finalised after 16 months.

Migration with Australia - year ended March 2024

There was a provisional net migration loss of 29,900 people to Australia in the year ended March 2024. This was made up of 17,000 migrant arrivals from Australia to New Zealand, and 46,900 migrant departures from New Zealand to Australia.

Traditionally, there has been a net migration loss from New Zealand to Australia. This averaged about 30,000 a year from 2004 to 2013, and 3,000 a year from 2014 to 2019.

The provisional net migration loss to Australia in the year ended March 2024 was made up of a net loss of 28,600 New Zealand citizens, and a net loss of 1,300 non-New Zealand citizens. This compares with a net migration loss to Australia of 18,700 in the year ended March 2023, made up of a net loss of 18,900 New Zealand citizens and a net gain of 200 non-New Zealand citizens.

In the March 2024 year, 53 percent of New Zealand citizen migrant departures were to Australia.

Net migration loss to Australia in 2023 (published in July 2024 and based on provisional data to December 2023) has more information.

These net migration estimates draw on two Infoshare series (select 'Tourism', then 'International Travel and Migration - ITM'):

• Estimated migrant arrivals by citizenship, visa type, and CLPR, 12/16-month rule (Quarterly) - this uses Stats NZ monthly estimates currently available to August 2024.
• Estimated migrant arrivals to Australia by CLPR, citizenship, and birthplace (Quarterly) - this uses Australian Bureau of Statistics quarterly estimates currently available to March 2024. Data for the June 2024 quarter will be available in mid-December 2024.

As the country of last previous residence (CLPR) of migrants arriving in New Zealand and Australia is not always known, an allowance for non-response to the CLPR question on both New Zealand and Australian arrival cards has been made.

Latest revisions

Migration estimates from May 2023 are provisional and subject to revision because it is not yet known whether some travellers are migrants or non-migrants.

Why migration estimates change has more information.

From August 2024 onwards, starting with the release of June 2024 estimates, a new training period was implemented for the international migration model.

Adjusting the training window for the international migration model (published 6 August 2024) and International migration: June 2024 (published 13 August 2024) have more information on the change of training period.

We encourage customers to make their own judgement on whether to use provisional migration estimates for the latest months, which have higher uncertainty, or provisional migration estimates for older months, which have lower uncertainty. Annual arrival and departure estimates are subject to notably less revision at five to six months after the reference period.

Comparison of provisional and final migration estimates: August 2017 to August 2024 contains a history of published migration estimates and revisions.

This month, revisions to the preceding month July 2024 were:

• migrant arrivals down 500 (3 percent). The average revision size to the preceding month was 1,300 (7 percent), and revisions were generally downwards, over the previous 12 months (July 2023 to June 2024).
• migrant departures down 500 (4 percent). The average revision size to the preceding month was 2,500 (16 percent), and revisions were all downwards, over the previous 12 months.
• net migration down 40. The average revision size to the preceding month was 1,800, and revisions were generally upwards, over the previous 12 months.

Provisional migration estimates

Comparisons between the August 2024 and 2023 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. These intervals reflect the model uncertainty, not the extent of future revisions to provisional data.

Migration estimates in more recent months have greater uncertainty and are therefore subject to larger revisions than estimates for earlier periods.

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.

Comparison of provisional and final migration estimates: August 2017 to August 2024 also has more information.

Why migration estimates change

The outcomes-based measure of migration with provisional and final estimates is the official way we measure migration in New Zealand.

International migration uses new official measure has more information.

To classify a border crossing as a migrant movement, we need to observe up to 16 months of travel history, and it takes 17 months before final migration estimates are available, using the 12/16-month rule.

To produce timely results, we use a statistical model to produce provisional migration estimates. As new data becomes available each month, the provisional migration model has more information about the border crossings it is trying to estimate. This causes shifts in the estimated number of migrant arrivals and migrant departures, and thus changes in the net migration estimates.
