New Zealand has a highly developed free-market economy. , New Zealand's nominal GDP was US$248 billion. In the 2025 IMF rankings New Zealand was the 52nd-largest national economy in the world when measured by nominal gross domestic product (GDP) and the 63rd-largest in the world when measured by purchasing power parity (PPP). New Zealand has one of the most globalised economies and depends greatly on international trade, mainly with China, Australia, the European Union, the United Kingdom, the United States, Japan and Korea. New Zealand's 1983 Closer Economic Relations agreement with Australia means that the economy aligns closely with that of Australia. Among OECD nations, New Zealand has a highly efficient and strong social security system; social expenditure stood at roughly 19.4% of GDP.

New Zealand's diverse economy is made up of various types of informal and formal organisations, divided between the public and private sectors. It has a sizeable service sector, accounting for 73% of all GDP activity . As a large island nation New Zealand has abundant natural resources and mineral wealth. Prominent manufacturing industries include aluminium production, food processing, metal fabrication, wood and paper products. Goods-producing industries accounted for 20% of GDP . The primary sector continues to dominate New Zealand's exports, despite accounting for only 7% of GDP . The information technology sector is growing rapidly.

The major capital market is the New Zealand Exchange (NZX). , NZX had a total of 338 listed securities, equity, debt and funds with a combined market capitalisation of NZD $226 billion. New Zealand's currency, the New Zealand dollar, also circulates in four Pacific Island territories. The New Zealand dollar is the 10th-most traded currency in the world. [pg.10 of PDF]

History

For many years New Zealand's economy was built on a narrow range of agricultural products, such as wool, meat and dairy. These products became New Zealand's staple and most valuable exports, underpinning the success of the economy, from the 1850s until the 1970s. For example, from 1920 to the late 1930s, the dairy export quota was usually around 35% of New Zealand's total exports, and in some years made up almost 45%. Due to the high demand for these primary products, manifested by the New Zealand wool boom of 1951, New Zealand had one of the highest standards of living in the world for 70 years.

In the 1960s, prices for these traditional exports declined, and in 1973 New Zealand lost its preferential trading position with the United Kingdom when the latter joined the European Economic Community. Partly as a result, from 1970 to 1990, the relative New Zealand GDP per capita adjusted for purchasing power declined from about 115% of the OECD average to 80%.

Between 1984 and 1993, New Zealand changed from a somewhat closed and centrally controlled economy to one of the most open economies in the OECD. In a process often referred to in New Zealand as Rogernomics, successive governments introduced policies which dramatically liberalised the economy.

In 2005, the World Bank praised New Zealand as the most business-friendly country in the world. The economy diversified and by 2008, tourism had become the single biggest generator of foreign exchange.

Early years Prior to European settlement and colonisation of New Zealand, Māori had a subsistence economy, the basic economic unit of which was the sub-tribe or hapū in which labour was divided. From the 1790s, the waters around New Zealand were visited by British, French and American whaling, sealing and trading ships. Their crews traded European goods, including guns and metal tools, for Māori food, water, wood, flax and sex. Their increasing lawlessness and plans for formal settlement by the New Zealand Company were two of the drivers behind the signing of the Treaty of Waitangi in 1840, which established New Zealand as a colony. Settlers continued to be dependent on Māori for food until the 1860s. From then immigrants became self-sufficient in farming, and started quarrying a variety of minerals including gold, which was discovered at Gabriel's Gully in Central Otago, leading to the Otago gold rush in 1861. Settlements flourished in areas where these quarries were established. In the 1880s, Dunedin became the richest city in the country largely on the back of investments from the gold rush.

Sheep farming began in the Wairarapa but soon spread up and down the east coast from Southland to the East Cape once rudimentary roads and transport became available. Much of the land used for farming was taken or leased from Māori. Sheep numbers grew quickly and by the mid-1850s, there were already a million sheep in New Zealand; by the early 1870s, there were 10 million. Wool became the first staple export, initially exported from the Wellington settlement in the late 1850s, although unrefrigerated meat and dairy products were exported as far as Australia.

In the 1870s, Julius Vogel was periodically both colonial treasurer and premier. He viewed New Zealand as a "Britain of the South Seas" and began the development of infrastructure in New Zealand investing heavily in roads, railways, telegraphs and bridges funded by public borrowing. Progress slowed after the collapse of the City of Glasgow Bank in 1878 which led to a contraction in credit from London, the centre of the world's financial system at the time. Economic activity was depressed for some years afterwards, until refrigeration was introduced in 1882. This enabled New Zealand to start exporting meat and other frozen products to the United Kingdom. Refrigeration transformed and shaped the development of the economy but, in the process, established New Zealand's economic dependence on Britain.

The success of refrigeration was directly related to the growth and development of farming in the country. In the 19th century, the bulk of economic activity was in the South Island of New Zealand. From around 1900, dairy farming became increasingly viable in areas which were less suitable for sheep, particularly in Northland, the Waikato and Taranaki. As dairying developed, the North Island slowly became more important to the economy. Britain became the sole market for meat and animal products in New Zealand, owing to the increase in its land cultivation and farming. The dairy farming can therefore be seen as a response to the powerful market demands in Europe, transforming not only New Zealand's countryside, economy and production techniques, but also causing migration in order to create the needed supply of dairy farming.

20th century The Reserve Bank of New Zealand was established as New Zealand's central bank on 1 August 1934. Up until that time New Zealand's monetary policy had been set in the United Kingdom, and the New Zealand Pound was issued by private banks. A separate central bank gave New Zealand's government control of monetary policy for the first time, although New Zealand remained part of the sterling area by pegging its pound to the British pound sterling until the introduction of the New Zealand dollar in 1967, after which the dollar was instead pegged to the United States dollar, before being floated in 1985.

By the mid-20th century, pastoral-farming products made up more than 90% of New Zealand's exports, 65% of which was going to Britain in the 1950s. As a former colony, the United Kingdom provided New Zealand with preferential trade quotas. This also enabled New Zealand to impose high tariffs on imported goods from other countries. Tough import controls gave local manufacturers the ability to produce similar products locally, broaden the base of jobs available in New Zealand and still compete against higher priced imports.

This prosperity continued up to 1955 at which point Britain started phasing out preferential quotas. From then on, what New Zealand received was dictated by the free market. As a result, during the 1950s and 1960s the country's standard of living began to slip as the export sector was no longer able to pay for the level of imported goods required to meet the country's growing consumerism.

Britain applied to join the European Economic Community (EEC) in 1961, but was vetoed by the French. The government of Keith Holyoake reacted by attempting to diversify New Zealand's export markets, signing the first free trade agreement (Australia New Zealand Free Trade Agreement) in 1965, and opening new diplomatic posts in Hong Kong, Jakarta, Saigon, Los Angeles and San Francisco. Britain applied again to join the EEC in 1967, and entered into negotiations for membership in 1970. Holyoake's deputy and successor, Jack Marshall, (briefly Prime Minister in 1972) negotiated continued access for New Zealand exports to the United Kingdom under the so-called "Luxembourg Agreement".

Britain gained full membership of the EEC on 1 January 1973, and all trade agreements with New Zealand came to an end, except the Luxembourg Agreement. By the end of that year, only 26.8% of New Zealand's exports were to Britain. This had a significant effect on the standard of living. In 1953, New Zealand had the third highest standard in the world. By 1978, it had dropped to 22nd place.

Having lost unrestricted access to its traditional market, New Zealand continued to search for alternative export markets and diversify its economy. The Government of Norman Kirk, who succeeded Marshall, put greater emphasis on expanding New Zealand's trade, especially with South East Asia. Following the Yom Kippur War in October 1973, an oil embargo was put in place by the Middle Eastern oil exporters, leading to the 1973 oil crisis. This compounded New Zealand's dire economic situation further. Inflation greatly increased as the cost of transport and imported goods soared, causing standards of living to decline.

Think Big

Following the 1979 energy crisis resulting from the Iranian Revolution of that year, Robert Muldoon, the prime minister between 1975 and 1984, instituted an economic strategy known as Think Big. Large scale industrial plants were established based on New Zealand's abundant natural gas. A new range of products for export such as ammonia, urea fertiliser, methanol and petrol were produced and with greater use of electricity (with the electrification of the North Island Main Trunk railway) with the goal that this would reduce New Zealand's dependence on oil imports.

Other projects included the Clyde Dam on the Clutha River, which was built to meet a growing demand for electricity, and the expansion of the New Zealand Steel plant at Glenbrook.

The Tiwai Point Aluminium Smelter, which opened in 1971, was also upgraded as part of the Think Big strategy and now brings in approximately NZ$1 billion in exports every year.

Most of these projects turned out to be ill-timed as they came on line at the same time as oil prices dropped during the 1980s oil glut. The price of crude went from more than US$90 a barrel in 1980, to about US$30 a few years later. Because these Think Big projects required massive borrowing to get started, public debt soared from $4.2 billion in 1975 when Muldoon became prime minister to $21.9 billion when he left office nine years later. Inflation remained rampant, averaging 11% in the 1980s. Once Labour came to power in 1984, many of these projects were sold to private industry as part of a wider sale of state-assets.

The Muldoon Government did, however, make some moves towards deregulation. For example, in 1982 it removed the transport licensing restrictions on road carriers carting goods more than 150 km, and turned the Railways Department into a statutory corporation.
