Why Are New Zealanders Leaving? Record Exodus to Australia Explained
Tory Whanau was the mayor of New Zealand's capital, Wellington. Now she is packing up her life and preparing to move to Melbourne, Australia. "There seems to be a brighter light overseas," the 42-year-old told The New York Times. She is not alone. More than 71,000 New Zealand citizens left the country over the 12 months ending in October 2025—equivalent to more than 1 percent of the population [citation:6].
The numbers are staggering. Yet the story is more complex than a simple "brain drain" narrative. While Kiwis are leaving in record numbers, immigrants from China, India, and the Philippines are arriving in even greater numbers, keeping New Zealand's population growing. This article examines why New Zealanders are leaving, where they are going, and whether the country should be worried.
📊 The Numbers: How Many Are Leaving?
According to Statistics New Zealand data released in May 2026, the migration picture is stark but nuanced [citation:1].
Annual net migration (to March 2026): The net gain was 24,200 people. However, this headline number conceals a dramatic split [citation:1]:
- Non-New Zealand citizens: Net gain of 60,800
- New Zealand citizens: Net loss of 36,400
In other words, for every Kiwi who left, more than 1.6 non-Kiwis arrived. The country is not depopulating—it is transforming [citation:10].
Annual departures of New Zealand citizens: In the year to March 2026, 62,700 New Zealand citizens left the country. That is down slightly from the peak of 64,000 in 2025 but remains near historic highs [citation:10][citation:7].
The exodus is not new. Between 2021 and 2025, annual New Zealand citizen departures rose from around 26,000 to 64,000. The share of the population leaving increased from 0.44 percent in 2021 to 1.34 percent in 2025 [citation:2].
📍 Where Are They Going? Australia Is the Top Destination
The pull across the Tasman Sea is overwhelming. Data shows that 63 percent of New Zealand citizens who leave are heading to Australia [citation:1]. The net loss of New Zealanders to Australia was estimated at 29,300 people in the year to September 2025 [citation:1].
This is not a new phenomenon. "People have been coming and going between Australia and New Zealand depending on different economic conditions for decades," says Sir Peter Gluckman, director of the Koi Tū Centre for Informed Futures [citation:7].
What has changed is the scale. In 2025, Australia recorded its highest intake of New Zealanders in more than a decade, with net migration forecasted at 35,000 New Zealanders for 2025-26 [citation:9].
🏛️ The Citizenship Surge: A 'Back Door' to Australia?
In July 2023, Australia relaxed its citizenship requirements for New Zealanders. Previously, New Zealanders had to apply for permanent residency before citizenship. Now, New Zealanders who have lived in Australia for four years or more can become Australian citizens directly [citation:9].
The result has been explosive. More than 92,000 New Zealand Special Category Visa holders applied for Australian citizenship between July 2023 and June 2025 [citation:9].
New Zealand Foreign Minister Winston Peters has raised concerns that his country is being used as a "stepping stone."
"We are concerned that those who gain residency will become citizens then, using their New Zealand passports, leave for fast-tracked visas in Australia. Almost half of our citizens already applying for Australian citizenship last year were not born here," Peters said [citation:9].
"New Zealand is being used as a stepping stone into Australia. We take them in, train them, up-skill them, look after their families, and then they emigrate. How is this an effective immigration policy?"
📈 Who Is Coming? China, India, and the Philippines Fill the Gap
While New Zealanders leave, others are arriving in large numbers. The top source countries for immigrants in the year to March 2026 were [citation:1]:
| Country | Arrivals | Departures | Net Gain |
|---|---|---|---|
| China | 18,500 | 7,400 | 11,100 |
| India | 17,000 | 5,600 | 11,400 |
| Philippines | 10,500 | 2,800 | 7,700 |
| Sri Lanka | 5,200 | — | 5,200 |
| United Kingdom | 4,800 | 4,400 | 400 |
| United States | 4,500 | 2,500 | 2,000 |
India, China, the Philippines, and Sri Lanka are the primary drivers of New Zealand's net migration gain [citation:10]. These immigrants are filling labor shortages in healthcare, IT, construction, and hospitality—sectors that New Zealand's departing citizens are leaving behind [citation:8].
🧠 Is It a 'Brain Drain' or Business as Usual?
The term "brain drain" implies that New Zealand is losing its most talented and educated citizens to other countries. But experts are divided on whether that characterization is accurate [citation:2].
A report from the Koi Tū Centre for Informed Futures, authored by Sir Peter Gluckman, Georgia Lala, and Christoph Grant, argues that the current migration patterns do not appear to exceed historical episodes [citation:7].
The report notes that previous increases in emigration occurred during the 1978 oil crisis, the 1987 stock market crash, and the 2008 global financial crisis. The current wave may be a post-COVID-19 adjustment rather than a permanent shift [citation:2].
The share of people departing who are aged 20 to 34 rose from 41 percent to 43 percent between 2021 and 2025, but that is merely a return to historical averages. "Youth mobility is a prominent part of Kiwi culture," the report states [citation:2].
"If those departing New Zealand elect to return home after some time working or studying abroad, they can bring with them new skills, experiences, ideas and networks."
However, there is a concerning trend: New Zealand citizen arrivals have declined from around 41,000 in 2019 to just 27,000 in 2025. Fewer Kiwis are coming back [citation:7].
"We simply do not have sufficient data or understanding of the people leaving New Zealand to be certain about the nature or nuances of the issue," Gluckman said [citation:7].
"Even the terminology 'brain drain' may be misleading: the educational levels of migrants are very similar to those of our population and may be higher than those leaving, although the data is very uncertain." [citation:2]
💰 Why Are They Leaving? The Pull of Australia
Higher wages, stronger employment prospects, and greater career opportunities are the primary drivers. A weak labor market and a sluggish post-pandemic economy in New Zealand have made the decision to leave easier [citation:6].
Infometrics chief executive Brad Olsen noted that New Zealand's unemployment rate is above 5 percent, yet arrivals remain high. The question, he said, is "what's driving all these migration flows?" [citation:2]
The answer, in part, is a well-worn path between the two countries. "It is a rite of passage for young New Zealanders to explore much of the world with their 'OE' (overseas experience), and this too may have been inhibited until recently by Covid-19 and related issues," Gluckman noted [citation:7].
👶 The Demographic Double Whammy: Low Birth Rates
The departure of young New Zealanders comes at a time when the country's birth rate has fallen to a historic low. The total fertility rate dropped to 1.53—well below the replacement rate of 2.1 [citation:3].
In the year to March 2026, only 57,027 babies were born in New Zealand, a decline of 1,512 from the previous year. Deaths numbered 37,821 [citation:3].
Natural increase (births minus deaths) contributed just 19,200 people to population growth, while net migration contributed 24,300. In the first quarter of 2026, migration accounted for a staggering 72 percent of population growth [citation:3].
🔮 The Future: A More Diverse, Older New Zealand
A report from Koi Tū Centre for Informed Futures warns that New Zealand is at a demographic "turning point." By 2048, 22 percent of New Zealanders will be aged 65 or older, and 48 percent will be of non-European ethnicity [citation:8].
"The changes should not come as a surprise. So why aren't we planning for them now?" asks Professor Paul Spoonley [citation:8].
The combination of low birth rates, an aging population, and reliance on immigration will reshape the country's workforce, economy, and social fabric over the coming decades.
Rather than asking whether we are experiencing a sudden brain drain, the real questions are: what has consistently drawn Kiwis overseas for decades, and how can we entice them, as well as other offshore talent, to settle back in New Zealand? [citation:7]

🎙️ TryOneRead Bottom Line
New Zealand is not emptying. The country's population continues to grow, driven by immigration from Asia. But the character of that growth is changing rapidly. The departing Kiwis—young, educated, and mobile—are being replaced by immigrants from different cultural backgrounds.
Is this a crisis? It depends on how you measure it. The economy is not collapsing. The workforce is not shrinking. But the country is losing a significant number of its young people to Australia, and many are not coming back. The long-term consequences of that loss are still unknown.
What is clear is that New Zealand needs better data on who is leaving and why. Without that information, policymakers are flying blind. The country also needs to confront its demographic future: an older, more diverse population sustained almost entirely by immigration.
The bright light overseas is real. But so is the bright light at home—if New Zealand can find a way to make it shine brighter.
