An increasing proportion of New Zealand’s immigrants are foreign citizens. In the 2010s – especially the later 2010s – a critical driver of immigration had been returning New Zealand citizens. As the headlines have indicated, that process of sourcing immigrants from the New Zealand diaspora has long finished.

Where have New Zealand’s post-covid immigrants come from? The following table shows immigration from the 31 countries which Statistics New Zealand follows. The estimates for the years-ended-August have just been released.

We note that not all intended migrations to New Zealand are successful. Most immigrants arrive on non-residence visas, and then have to apply for permanent residence or other long-stay visas. Unsuccessful immigrations arise both from failures to secure the desired permission, or from immigrants themselves having second thoughts. There are two possible outcomes of unsuccessful immigration: return migration, or onward migration.

Onward migration may take place following immigrants’ success in gaining New Zealand passports. But that is not unsuccessful immigration, and it’s not shown here. The data below looks at the 12-month period ending August 2023, and deducts the migrant departures for each nationality in the following 12 months (ending August 2024). For comparison, the table also shows 12-month period ending August 2024, deducting the migrant departures for each nationality in the 12 months ending August 2025.

These data are estimates for successful immigration (as defined above) by migrants’ nationalities:

It turns out that Philippines is the 2023 ‘winner’. Philippines consistently has few return or onward migrants. We note that the Philippines’ number dropped more in 2024 compared to India, probably reflecting the larger numbers of Indian migrants who arrived as tertiary students.

Two other stand-out immigrant countries – relative to their source populations – are Sri Lanka and Nepal.

The dominant groups of countries are our Pacific neighbours (Oceania); and South and East Asia. In this context we should note that a substantial majority of immigrants from Philippines, Malaysia, and Indonesia are ethnic ‘Austronesians’, the same broad ethnic group as our indigenous Māori and most of our Oceanian immigrants. Immigrants from Philippines are a particularly good fit, because of their similar Christian culture and because they are ethnic cousins of indigenous Aotearoans.

That’s not to say that any other national group is a bad fit. Most of our immigrants seek to integrate sufficiently to become Kiwis, without being under pressure to assimilate into Euro-Kiwi norms. Interestingly, of the six top immigrant-source countries, New Zealand only has direct flights with two: China and Fiji.

We note that the richer Asian nations feature well down the list. And we note the disproportionately low representation of nationalities with mainly Muslim populations. Indonesia, with 2½ times the population of Philippines has only 2½ percent of the Philippines’ successful immigration. Indonesia, our near-invisible near-neighbour, is the fourth most populous country in the world, and may well have more people than the United States by 2050.

With slightly more immigrants than from Indonesia is Pakistan, the world’s fifth most populous country, and a country with strong sporting links to New Zealand. But Pakistan is way below India in the above table. A surprising omission from the table is Bangladesh, the world’s eighth most populous country, with more residents than Russia (the world’s number nine). Bangladesh does have a significant community in New Zealand, including my GP doctor. I suspect that Bangladeshis feature strongly in the ‘other Asia’ category, along with Cambodians who continue to operate small bakeries in Aotearoa New Zealand. Another country of importance missing from the list is Singapore, whose airline does bring many if not most of our South Asian immigrants.

Other countries not mentioned so far in the world’s top-ten by population are Brazil, Nigeria, and Mexico. Of these only Brazil features in the table above, although Nigeria may well have a significant presence in ‘other’, and Mexico has had some high-profile immigrants to Aotearoa New Zealand. Brazilian immigration, which appears to be dropping off, may return once China Eastern commences flights from Auckland to Buenos Aires.

We see the richer countries in Europe and the Americas (traditional sources of immigration), and Australia, feature in the bottom half of the ‘Top-31′; much more so for 2024 than for 2023. We note that the negative numbers in 2024 mean that more people with those countries’ passports departed in 2025 than arrived in 2024.

Ukraine doesn’t feature, though it might be a major part of ‘other Europe’. Czechia, which I am surprised Stats NZ have included, may be taken as a proxy for Eastern Europe. Also, ‘other Africa’ has held up while South African successful immigration has halved.

The data all reinforces the fact that New Zealand is a demographic turnover country, with the momentum of immigration coming from much poorer non-Muslim countries, and with a significant outflow of richer-country migrants.

For some up-to-date perspective, the table below shows estimated immigration for the featured countries in the year to August 2025. It shows an increase in migrant arrivals from some richer countries, such as United States, Australia, Japan, Germany and France; however, it is likely that similar numbers of these nationalities will leave New Zealand in the next 12 months as arrived in the previous 12 months. Many from France will actually be from New Caledonia; from Oceania rather than from Europe.

Finally, total arrivals of foreigner immigrants were 201,950 in the year to August 2023; 142,661 in the year to August 2024; and 112,591 in the year to August 2025; much lower than immediately post-covid, but still high. Total departures of foreigner immigrants were 35,972 in the year to August 2023; 46,099 in the year to August 2024; and 54,092 in the year to August 2025.

So, in the last year, foreigner migrant departures from New Zealand had reached almost half of foreigner migrant arrivals. This suggests that, for many, immigration to New Zealand is a fraught and often unsuccessful experience.

Analysis by Keith Rankin.

These three countries are very useful comparators because they have broadly similar demographics – especially population age structures – to each other. Further they have comparable living standards. The Republic of Ireland has a population the same size as New Zealand (and a similar climate); Australia has close to five times the population of each of the others.

Of the above charts, Ireland best shows the three main waves of mortality in the Covid19 Pandemic. [Note that I will capitalise the word ‘pandemic’ for a WHO-declared pandemic. Otherwise uncapitalised.] There are very clear covid mortality peaks in Ireland in April 2020, January 2021, and December 2022. Other than these peaks there are clear periods of elevated mortality, the second half of 2021 and most of 2022. 2023 also, from March.

Ireland’s population has been growing more slowly this century than Australia’s and New Zealand’s. Death tallies before the Pandemic years were not noticeably growing from 2015 to 2019; compare Australia below. There was an influenza pandemic from late 2016 to about April 2018; the high numbers of deaths in Ireland in January 2017 and December 2017 reflect this. (I have omitted 2016 and 2018 to avoid chart clutter. For Ireland, influenza pandemic deaths actually peaked in January 2018, and extended into March of that year.)

The most obvious difference in the New Zealand chart is the southern hemisphere seasons. The second most obvious difference in New Zealand is the lack of obvious Covid19 waves.

The scales of the two charts are fully comparable, because of the near-identical populations of each country. But a careful look will show that ‘normal’ – ie baseline – summer deaths in Ireland are lower than in New Zealand. Ireland’s population may have better baseline health than New Zealand’s. Or, New Zealand may have more deaths because it has a higher population of post-war ‘baby-boomers’ than Ireland; a population which is now starting to die in greater numbers.

The New Zealand data are worrying in other ways, however. While 2017 clearly shows the 2016-2018 influenza pandemic, with its July 2017 mortality peak, summer data for 2017 and 2019 don’t show large increases in deaths arising from population growth. The period from March to July 2019, in the absence of known epidemic illness, nevertheless looks like a protracted period of deaths triggered by early seasonal viruses. (Indeed, I recall from my former workplace that there were a lot of ‘bugs’ around for parts of 2019.)

If we regard the April to June periods in 2017 and 2019 as having elevated death tallies, then 2021 looks like a normal year in New Zealand, even allowing for population growth. Yet it wasn’t a normal year. It was the peak year of the Covid19 panic; the year of the most extreme public health mandates, with an effectively shut international border and with face-masking required in many settings. The big question is to ask why 2021 was not more like 2020. In the winter of 2021, New Zealand had no Covid19 to speak of, and no influenza.

Elevated death tallies reappeared in March 2022, continuing through to January 2023. While these were clearly linked to Covid19, there was no mortality peak anything like that which Ireland experienced in December that year. My guess is that the timing of mortality in New Zealand reflected the timing of booster vaccinations against Covid19, whereas Ireland was caught unawares that December.

A good check on these tentative conclusions for New Zealand is Australia. (The scale is five times higher, reflecting that Australia’s population is five times greater.) Australia shows most of the same features as New Zealand in the years before 2020, though in a muted way. Australia shows more consistently than New Zealand the impact of population growth before 2020 being reflected in more deaths each year than the previous year. We see that in the spring months (September to November) Australian deaths are generally lower than New Zealand’s; probably because winter lingers for longer in New Zealand.

Australia shows the same problem in 2021 as New Zealand; normal winter deaths despite highly abnormal circumstances. As in New Zealand, there almost certainly were ‘killer viruses’ in both countries that year. Deaths to some extent will have been people who would otherwise have died in 2020, but avoided viruses then because of the lockdowns and physical distancing. Also, weakened immunity arising from the lack of normal exposure to respiratory viruses in 2020 will have increased the chances of vulnerable people dying in 2021 after contracting such a cold virus. The 2021 mortality peaks were higher in New Zealand than in Australia.

Australia shows a classic Covid19 mortality peak in January 2022, before the ‘Omicron’ variant of Covid19 was discovered in New Zealand. Australia had covid exposure peaks in December 2021, much of that being the Delta variant, pre-Omicron. In the autumn and early winter of 2022, Australian mortality data show a shorter and lower ‘Omicron wave’ than New Zealand data.

All three countries continue to show elevated levels of mortality this year, though this is obscured in New Zealand by the problematic numbers of deaths in the autumns and early winters of 2017 and 2019. New Zealanders in the first four months of this year have had slightly more deaths (adjusting for population) than Australians. This may reflect New Zealand’s relatively more overstretched healthcare system, noting from having myself spent some time in Australia this year that Australians also see their healthcare system as overstretched.

South Auckland’s poor turnout for the 2018 Aotearoa New Zealand national census could have cost the region $130 million in health funding.

And, according to an expert, that cash could have helped tackle the area’s battles with diabetes and obesity.

Te Whatu Ora Health New Zealand said the defunct Counties Manukau District Health Board lost $130m in health funding in its last four years due to the low turnout in the area during the 2018 census.

Information from the five-yearly stocktake helps determine how billions of dollars in government spending is allocated across health, education, transport, infrastructure and other services.

Counties Manukau has more people with diabetes than any other health region in the country.

Te Whatu Ora (Counties Manukau) Director of Population Health Gary Jackson said additional money would help fund programmes to battle two issues affecting many people in the region.

He said there were 52,000 diabetics in Counties Manukau and that figure was growing by 2000 people a year. It is also home to 19 percent of all New Zealanders in the most extreme BMI group.

Only 71 percent response
Figures released by Stats NZ this week show only 71 percent of people in South Auckland have so far completed the census in 2023, compared to 83 percent nationwide.

Te Whatu Ora Chief Financial Officer Rosalie Percival said getting people to provide their details was vital to ensure areas like Counties Manukau got the healthcare services they needed.

“Health providers know about the people who turn up at their door needing care — but they have no other way of knowing about the presence of people who haven’t recently needed to use the health system,” she said.

“The data gained from the census helps to inform important decisions about planning for the needs of local areas and subsequently healthcare spending.”

However, Buttabean Motivation (BBM) founder Dave Letele said getting people to complete the census was not easy.

Letele, who is potentially standing for Te Pāti Māori this year, was an ambassador for Census 2023 and was involved in a social media campaign which kicked off late last year to get more people to take part.

“There’s a massive distrust between our people and the government and that’s what we need to overcome,” Letele said.

Wary about personal information
He said as a result a lot of people were wary about sharing their personal information with authorities.

“But it’s not just something you can throw money at to fix it.”

Deputy Government Statistician and deputy chief executive for census and collection operations Simon Mason confirmed the turnout at the last census in 2018 was poor in Counties Manukau.

“That is why it is critically important that people complete the census — so their communities are counted . . .”

Mason said the 2023 event was designed to address barriers to participation, including having more collectors and alternate formats for people to complete it and support a wider range of people.

A spokesperson for Stats NZ said it would still have field teams collecting people’s responses until May 3 and will be running census support events until June 4.

Pacific Media Watch reports that the Counties Manukau health population is ethnically diverse with the largest Pacific population and second largest Māori popukation of any New Zealand health board.

In the 2018 census, 16 percent of the population served by CM Health identified as Māori, 22 percent as Pacific, 28 percent as Asian and 34 percent as NZ European/other groups.
