New Zealand is, in the most fundamental sense, a country made by migration. Every person living in New Zealand today is either a migrant or a descendant of migrants — from the Polynesian navigators who first discovered these islands around 1280 CE, to the British settlers who arrived in waves from the 1840s, to the hundreds of thousands of people who have arrived from Asia, the Pacific, Africa, and the rest of the world in recent decades.
Migration has never been a side story in New Zealand's history. It has been the main story. It shaped the land, the culture, the economy, and the society. And it continues to shape all of those things today — in ways that are more complex, more contested, and more consequential than they have ever been.
The First Migration: Polynesian Settlement
The first people to settle Aotearoa came from East Polynesia, most likely from the region Māori later called Hawaiki — now believed to correspond broadly to the Cook Islands and Society Islands. They navigated thousands of kilometres of open Pacific Ocean in double-hulled canoes, reading stars, winds, and ocean currents with extraordinary skill.
Archaeologists estimate the first settlers arrived no later than 1300 CE. Over the following centuries they developed a distinctive culture — Māori — with its own language, social structures, governance systems, art, and relationship to the land. By the time Europeans arrived, the Māori population may have reached 100,000 or more.
This first migration established New Zealand not as an empty land waiting to be discovered, but as a settled, governed society with its own deep history. Understanding that context is essential to understanding everything that followed.
European Settlement: The Transformative Wave
European contact began in 1642 with Dutch explorer Abel Tasman and accelerated after James Cook's voyages from 1769. By the 1830s, whalers, traders, missionaries, and settlers were arriving in growing numbers.
The signing of Te Tiriti o Waitangi in 1840 formalized British sovereignty and opened the gates to organised, large-scale European settlement. The New Zealand Company established settlements at Wellington, Nelson, New Plymouth, Otago, and Canterbury. The colonial government — and later Julius Vogel's ambitious public works programme of the 1870s — actively recruited and subsidized migrants from Britain and Ireland, aiming to transform New Zealand into a prosperous British colony.
The non-Māori population grew from around 2,000 in 1840 to over 250,000 by the 1870s. Gold discoveries in Otago in 1861 and on the West Coast in 1865 triggered a dramatic surge in arrivals — 1863 saw the largest single-year gross migration in New Zealand's history as prospectors flooded across the Tasman from Victorian goldfields.
This wave of British and Irish settlement permanently and fundamentally transformed New Zealand — its language, laws, institutions, economy, and the balance of power between Māori and the new arrivals. Māori land was progressively taken through war, legal mechanisms, and economic pressure. The population that had governed these islands for centuries was reduced to a marginalized minority within a few decades.
Pacific Migration: Labour and Community
From the 1940s a new wave of migration brought people from New Zealand's Pacific neighbours — initially as workers filling labour shortages in post-war New Zealand's expanding economy.
Cook Islands women arrived in the 1940s and 1950s as domestic workers. Tongans began arriving on temporary work permits in the 1950s. Samoans, Niueans, and Tokelauans followed through the 1950s and 1960s. These communities settled primarily in Auckland — in suburbs like Ōtāhuhu, Māngere, and Porirua — and built vibrant, tightly connected communities that became integral parts of New Zealand society.
Pacific migration was not always welcomed on equal terms. Many arrivals came on temporary permits with no clear pathway to permanent residence. In 1974 and 1975 — in a period that has since been condemned as one of the most racist episodes in modern New Zealand history — the government conducted what became known as the Dawn Raids. Pacific Island people, targeted because of concerns about overstayers, were subjected to early morning police raids on their homes. The raids were widely condemned as discriminatory and traumatic for Pacific communities.
Despite that history, Pacific peoples have become a deeply embedded and important part of New Zealand society — contributing enormously to culture, sport, community life, and the workforce. The Pacific population today is around 8 percent of the total — a young, growing community concentrated in Auckland.
The Asian Wave: The Transformation of Modern New Zealand
From the early 1990s, New Zealand's immigration system shifted toward a points-based model that prioritised skills and qualifications over national origin. This change opened the door to large-scale migration from Asia — particularly from China, India, South Korea, and later the Philippines, Sri Lanka, and other countries.
In the 1993 census, the Asian population made up around 3 percent of New Zealand's total. By the 2023 census it had grown to 17.3 percent — a transformation achieved in a single generation. This shift has been the most significant demographic change in New Zealand's modern history.
Asian migrants have settled primarily in Auckland, which has become one of the most ethnically diverse cities in the world relative to its size. They have brought different languages, religions, food cultures, business networks, and educational traditions. They have filled critical workforce shortages in healthcare, technology, engineering, and hospitality. International students — primarily from China and India — have become a significant source of revenue for universities and a pipeline of skilled migrants seeking permanent residence.
The speed and scale of this transformation has not always been managed well. Concerns about housing pressure, infrastructure strain, and social cohesion have been genuinely felt. At the same time, there has been a history of anti-Asian sentiment in New Zealand public discourse — including explicit political messaging about Asian migration — that has not always reflected the actual contributions migrants make.
How the Migration System Works
New Zealand uses a points-based immigration system — a model designed to attract migrants with skills, qualifications, and work experience that the economy needs.
The main pathways for permanent residence are:
Skilled Migrant Category — for people with qualifications and work experience in occupations New Zealand needs. Points are awarded for age, qualifications, job offer, and other factors.
Green List — a fast-track residence pathway for people in specific high-demand occupations including healthcare, construction, and trades.
Family-sponsored migration — for partners, dependent children, and in some cases parents of New Zealand citizens and residents.
Investor visas — for people who invest significant capital in New Zealand.
Humanitarian and refugee categories — New Zealand accepts a refugee quota — currently around 1,500 per year — of people resettled from overseas refugee camps through the United Nations system.
Working Holiday and student visas — temporary visa holders who often form a pipeline toward permanent residence.
The system is actively managed — the government adjusts settings, eligibility criteria, and approved occupation lists in response to economic conditions and workforce needs. When the economy is growing and labour is scarce, settings are typically more open. When the economy slows and unemployment rises, they often tighten.
The New Zealand Diaspora: Migration Out
Migration is not just about people arriving. It is equally about people leaving.
New Zealand has one of the highest emigration rates of any developed country relative to its population. In the year to April 2025, New Zealand saw a net loss of 45,600 of its own citizens — more citizens left than returned. Australia is by far the primary destination, with the right to live and work freely under the trans-Tasman arrangement making it accessible to almost any New Zealander.
This outflow — primarily of young, educated, working-age New Zealanders — is a persistent and significant drain. They take their skills, their tax contributions, and their potential economic output with them. Some return eventually, bringing international experience and networks back. Many do not.
The brain drain is not simply a function of people preferring Australia. It reflects real differences in wages, living costs, housing affordability, and economic opportunity. When those gaps are large, more people leave. When they narrow, fewer leave and more return. In 2025, New Zealand citizen departures declined for the first time since 2020 — a modest sign that the economic recovery was beginning to reduce the pull of emigration.
What Migration Does to New Zealand
Migration shapes New Zealand across virtually every dimension of society.
The economy Migration is the primary mechanism through which New Zealand fills workforce shortages. Healthcare — particularly nursing and medicine — depends heavily on overseas-trained professionals. Construction could not function at its current capacity without migrant workers. Aged care, hospitality, agriculture, and technology are all significantly supported by migrant labour.
When migration is high, consumer demand rises, the tax base expands, and economic activity increases. When it falls sharply — as it did during the Covid-19 border closure — workforce gaps open, businesses struggle to operate, and economic growth slows.
Housing Migration is the most significant demand-side driver of New Zealand's housing pressures. Each new permanent resident needs somewhere to live. When migration runs faster than housing construction — as it has at various points — prices rise and affordability falls. The relationship between migration and housing costs is direct, persistent, and politically contentious.
Infrastructure and services More people require more schools, hospitals, roads, water, and public transport. When population growth — driven by migration — consistently outpaces infrastructure investment, the result is congestion, stretched services, and declining quality of urban life. Auckland's infrastructure challenges are substantially a product of population growth that infrastructure spending has not kept pace with.
Cultural life Migration has made New Zealand one of the most diverse societies in the world relative to its size. That diversity enriches food, art, music, business, and public life. It brings different ways of seeing and doing things that New Zealand-born citizens would not otherwise encounter. Immigrants represented 29 percent of the population as of the 2023 census — nearly one in three people living in New Zealand was born overseas.
Identity Migration has complicated and enriched New Zealand's sense of itself. The country is no longer simply bicultural — Māori and Pākehā — though that founding relationship remains central and legally significant. It is increasingly multicultural, with dozens of languages spoken in Auckland schools, dozens of faiths practiced in its communities, and dozens of national identities woven into its social fabric. Managing that complexity — building genuine social cohesion across a highly diverse population — is one of the ongoing challenges of New Zealand's social life.
The Tensions Migration Creates
Migration produces real benefits. It also produces real tensions — and being honest about both is essential.
Housing and infrastructure pressure When migration runs faster than the country's capacity to build and provide services, real costs fall on existing residents. Housing becomes less affordable. Schools become more crowded. Roads become more congested. These pressures are not imaginary — they are felt most acutely by people on lower incomes who compete for housing and services with new arrivals.
Workforce displacement and wages Large inflows of migrant workers in particular sectors can put downward pressure on wages for workers already in those sectors. The evidence is mixed and context-dependent, but the concern is legitimate. New Zealand has used employer-sponsored work visas in ways that have sometimes allowed employers to avoid paying market rates by relying on migrant labour with limited bargaining power.
Social cohesion Rapid demographic change can outpace social institutions' capacity to manage it. Schools, health services, and community organizations need time to adapt to serving more diverse populations. When that adaptation is slow, tensions emerge — between established residents and new arrivals, between different cultural communities, and within political debate.
The Treaty dimension Māori have particular standing in relation to migration because of Te Tiriti o Waitangi. Each wave of migration has altered the demographic and political balance in New Zealand in ways that affect the Crown-Māori relationship. Large-scale migration from Asia has made New Zealand a more genuinely multicultural society — but it has also made the political calculus around bicultural commitments more complex.
Where Things Are Heading
Annual net migration in 2025 was approximately 14,200 — significantly lower than the peak of 135,500 recorded in the year to October 2023, which followed the post-Covid border reopening. BERL economists project that without sustained net migration New Zealand's population would peak in the early 2040s and then begin to decline as deaths outnumber births.
That arithmetic makes migration not optional but structural. New Zealand needs a consistent inflow of people to maintain its workforce, fund its public services, and grow its economy. The question is not whether New Zealand should accept migrants — it must — but how many, from where, on what terms, and with what support systems to ensure successful settlement and genuine social integration.
The main source countries of recent arrivals include India, the Philippines, China, Sri Lanka, the United Kingdom, and South Africa — a diverse mix that reflects New Zealand's global reach as a migration destination.
The government's immigration settings will continue to evolve in response to economic conditions, workforce needs, housing pressures, and political sentiment. Managing that evolution — balancing openness with capacity, diversity with cohesion, economic need with social sustainability — is one of the most complex and consequential policy challenges New Zealand faces.
Quick Q&A
Why does New Zealand need migrants? Because the birth rate has fallen below the replacement level needed to maintain the population. Without net migration New Zealand's population would eventually decline, shrinking the workforce, reducing the tax base, and making it harder to fund public services including superannuation and healthcare for an ageing population.
Where do most migrants to New Zealand come from? In recent years the main source countries have been India, the Philippines, China, Sri Lanka, the United Kingdom, South Africa, and Australia. The mix reflects New Zealand's points-based immigration system which prioritizes skills and qualifications, drawing applicants from countries with large numbers of people holding the qualifications New Zealand needs.
How does migration affect housing prices? More people need more homes. When migration runs faster than housing construction — as it has at various points — demand exceeds supply and prices rise. Migration is one of several factors driving housing unaffordability in New Zealand, alongside land use restrictions, construction costs, and interest rates.
What is the New Zealand Superannuation connection to migration? Superannuation is funded by the taxes of working-age New Zealanders. As the population ages — more retirees drawing payments, fewer workers funding them — the fiscal pressure grows. Migration of working-age people provides additional workers and taxpayers who help fund superannuation for current retirees.
What were the Dawn Raids? A series of police raids in 1974 and 1975 targeting Pacific Island people suspected of overstaying their visas. The raids were conducted in the early hours of the morning and disproportionately targeted Pacific communities while largely ignoring overstayers from other backgrounds. They have since been widely condemned as racist and traumatic. The New Zealand government issued a formal apology in 2021.
How many New Zealanders live overseas? A significant number — primarily in Australia where they have the right to live and work freely. In the year to April 2025 there was a net loss of 45,600 New Zealand citizens — more left than returned. The New Zealand diaspora in Australia, the United Kingdom, and elsewhere is estimated at over half a million people.
Key Takeaway
Migration is not just a policy question — it is the fundamental process through which New Zealand has been built, rebuilt, and continuously reshaped over more than 700 years. Every wave of migration has transformed the country and left permanent marks on its culture, economy, and identity. The migration decisions being made today — about how many people to accept, from where, on what terms, and with what support — will shape the New Zealand of the next generation as surely as the decisions made in the 1840s, the 1870s, and the 1990s shaped the New Zealand of today.
