New Zealand has a population of approximately 5.3 million people as of 2025, making it roughly the 120th most populous country in the world. For a developed nation occupying a land area comparable to the United Kingdom or Japan, this is a remarkably small population, which is why New Zealand remains one of the least densely settled countries on Earth. Nearly all of those people are crowded into a handful of cities, while vast mountain ranges, fiords, and forests stay almost empty.
How Many People Live in New Zealand?
New Zealand's resident population sits at about 5,300,000, spread across two main islands and dozens of smaller ones in the southwestern Pacific. To put that figure in perspective, more people live in the Sydney metropolitan area than in the whole of New Zealand, and a single borough of a large global city can rival an entire New Zealand region. The country adds tens of thousands of residents each year, but its overall size keeps it firmly in the lower half of the global population rankings.
What makes the number striking is the contrast between land and people. New Zealand stretches across roughly 268,000 km², giving it a population density of only about 20 people per square kilometre, far below the global average and a fraction of the density seen in Europe or East Asia. Vast tracts of the country, from the Southern Alps to Fiordland, remain almost entirely uninhabited, and large parts of the population cluster into a few coastal cities. This combination of a temperate, productive landmass and a small population is one reason New Zealand has long been able to sustain large agricultural exports relative to its size.
Population Growth and Trends
New Zealand's population is currently growing at an annual rate of around 0.82%, a moderate pace by global standards. That growth comes from two sources: natural increase (births minus deaths) and net migration. The fertility rate has fallen to roughly 1.6 children per woman, which is below the replacement level of 2.1, meaning the country increasingly relies on immigration to keep growing rather than on births alone.
Newcomers arrive from a wide range of countries, with the United Kingdom, China, India, and the Philippines among the most common sources. New Zealand has historically experienced a "brain drain," with many young Kiwis moving to Australia in search of higher wages, but periods of strong domestic economic performance have at times reversed or slowed that outflow. Migration figures can swing sharply from year to year, which is why New Zealand's headline growth rate is far more volatile than its steady birth and death rates would suggest.
Demographers project the population could reach roughly 6.5 million by 2050, with the share of older residents rising steadily as life expectancy climbs past 82 years. Like most wealthy nations, New Zealand faces a gradually ageing population, a trend that shapes long-term planning for healthcare, pensions, and the workforce.
Where New Zealanders Live
New Zealand is one of the most urbanised countries in the world, with the large majority of residents living in cities and towns rather than the countryside. The North Island is home to most of the population, while the South Island, though larger in area, is more sparsely settled and dominated by farmland, lakes, and alpine terrain.
- Auckland is by far the largest city, with about 1.7 million residents, roughly one-third of the entire national population. It is the economic engine of the country and a famously multicultural hub with a strong Pacific and Asian presence.
- Wellington, the capital, has around 215,000 city residents and about 430,000 across its wider metropolitan area. It holds the distinction of being the southernmost capital of any sovereign state.
- Christchurch, with roughly 390,000 metro residents, is the largest city of the South Island and was extensively rebuilt following the devastating earthquakes of 2010 and 2011.
- Hamilton, Tauranga, and Dunedin round out the next tier of urban centres, each anchoring its own region but far smaller than Auckland.
The dominance of Auckland means the country's demographics are unusually concentrated in one place. This concentration influences everything from housing costs and traffic to where new infrastructure and immigration tend to flow.
A Diverse and Changing Society
New Zealand's population has become steadily more multicultural. Around 70% of people identify as European (often called Pākehā), about 17% as Māori, roughly 15% as Asian, and around 8% as Pacific Islander. Because residents can claim more than one ethnicity, these figures overlap. The Māori share of about 17% is among the highest proportions of any indigenous people in an English-speaking nation, and Māori culture, language, and place names are woven deeply into national identity.
English and Māori are both official languages, with New Zealand Sign Language also holding official status. Religiously, the country has shifted dramatically: while about 37% identify as Christian, close to half now report no religion at all, reflecting one of the more secular societies in the developed world. The median age stands at around 37 years, slightly younger than many European nations thanks to ongoing migration of working-age adults.

How New Zealand Compares Internationally
Globally, New Zealand's roughly 5.3 million people place it in the company of nations like Norway, Ireland, and Costa Rica in terms of total population, but its low density sets it apart. Among developed countries, only a few, such as Iceland, Australia, and Canada, have a lower number of people per square kilometre. This gives New Zealand an unusual character: a wealthy, highly connected society that still has enormous expanses of empty land.
The country's small population also helps explain its outsized international profile in areas like agriculture and sport. With limited domestic labour, New Zealand has built an economy heavily oriented toward exporting dairy, meat, and produce, and its compact society can mobilise around national events in ways larger countries find harder.

Frequently Asked Questions
Is New Zealand's population growing or shrinking?
It is growing, but slowly, at about 0.82% per year. Because the fertility rate of roughly 1.6 is below replacement level, much of this growth depends on immigration rather than natural increase, and the rate can change quickly when migration trends shift.
What is the largest city in New Zealand?
Auckland is the largest city, home to around 1.7 million people, or about a third of the entire country. Wellington is the capital, while Christchurch is the largest city on the South Island.
Why does New Zealand have such a small population?
New Zealand is geographically isolated, settled relatively late by humans, and much of its terrain is mountainous or otherwise difficult to inhabit. Combined with a modest birth rate, this keeps the total population low and the density among the world's lowest.
What percentage of New Zealanders are Māori?
About 17% of the population identifies as Māori, the indigenous Polynesian people of New Zealand. This is one of the highest indigenous population shares of any Anglophone country.
