Cook Islands Factsheet

Customs and Culture

Cultural Attributes

The Cook Islands possesses a rich and distinctive Polynesian culture shaped by centuries of tradition, strong community bonds, and a deep connection to the Pacific Ocean. The islands' people, known as Cook Islanders or M?ori (not to be confused with New Zealand M?ori, though the two groups share ancestral ties), maintain cultural practices that permeate daily life, from language to music, dance, and craft. The Cook Islands M?ori language is one of two official languages alongside English and remains widely spoken across the islands. Oral tradition has historically been the primary means of passing down genealogies, legends, and knowledge, a practice that continues to be honored by elders and community leaders. Dance holds a central place in Cook Islands culture. The traditional form known as ura is performed at community celebrations, festivals, and the annual Te Maeva Nui festival, which commemorates the nation's self-governance established on August 4, 1965. This festival brings together performers from all fifteen islands and serves as a major showcase of cultural identity. The rhythmic hip movements and elaborate costumes characteristic of Cook Islands dance distinguish it from other Polynesian traditions. Tivaevae, intricately hand-sewn patchwork quilts, represent another significant cultural art form. Introduced through missionary influence in the nineteenth century, the practice evolved into a deeply local tradition. These quilts are often made collaboratively by groups of women and are presented as gifts at important life events such as weddings and funerals, carrying considerable social and emotional weight. Religion plays an important role in community life, with the majority of Cook Islanders identifying as Christian. The Cook Islands Christian Church, established by London Missionary Society activity in the nineteenth century, remains the largest denomination. Church attendance and community service connected to religious institutions are common practices. Extended family networks, known as the vaka system, structure social organization and responsibilities. Decisions about land, community matters, and cultural events are frequently made collectively, reflecting a broader Pacific value of communal obligation over individual interest.

Recommended Vaccinations
How important is it to do your research about vaccinations? It might just save your life! Make yourself aware of the different types of vaccinations and which ones you may need to travel to your destination. Schedule an appointment with your doctor at least four to six weeks before you travel to ensure you receive all important shots. Be sure that you and your family are up to date on your routine vaccinations. Which vaccinations you need will depend on a number of factors including your destination, whether you will be spending time in rural areas, the season of the year you are traveling, your age, health status, and previous immunizations.

History

Historical Eras

  1. Polynesian Settlement

    900 – 1821

    Migrants from French Polynesia and Samoa settled the fifteen islands from around the 13th century, establishing chiefly societies governed by ariki. Rarotonga became a crucial waypoint on trans-Pacific voyaging routes, with oral tradition crediting its navigators — most famously the 1350 fleet of seven vaka from Avana Harbour — as among the founding ancestors of New Zealand's Māori people.

  2. Missionary Era

    1821 – 1888

    London Missionary Society representatives arrived in 1821 and rapidly converted influential ariki, transforming the social and legal fabric of the islands. Working alongside chiefs, missionaries drafted legal codes and abolished violent dispute settlement, producing remarkable political stability. European contact accelerated, with Spanish navigator Álvaro de Mendaña making the first recorded European sighting in 1595 and Captain James Cook surveying the islands between 1773 and 1777.

  3. British Protectorate

    1888 – 1901

    At the petition of leading ariki seeking protection from rival colonial powers, Britain declared a protectorate over the Southern Group in 1888, extending it to the Northern Group islands in the early 1890s. New Zealand, itself a self-governing British colony, funded and effectively controlled the resident consul, who held advisory and legislative veto powers. Tensions between traditional leaders and New Zealand administrators grew, with some ariki ultimately requesting direct British annexation.

  4. New Zealand Administration

    1901 – 1965

    On 27 September 1900 the New Zealand Parliament approved annexation, and the islands formally became a New Zealand territory in 1901. Colonial administration restructured land tenure, governance, and public services, while significant emigration of Cook Islanders to New Zealand began reshaping island demographics. The period saw gradual moves toward internal self-governance culminating in a United Nations-supervised plebiscite process.

  5. Self-Governance

    1965 – present

    In 1965 Cook Islanders voted to become a self-governing territory in free association with New Zealand, retaining New Zealand citizenship while managing their own internal affairs. The economy has relied heavily on tourism, remittances, and foreign aid, while persistent emigration of skilled workers and recurring government deficits remain structural challenges. Natural disasters, including four cyclones in rapid succession in 2005, have periodically set back development gains.

Health Information

Life Expectancy at Birth
Life expectancy at birth in the Cook Islands is relatively high compared to many Pacific island nations, reflecting the country's access to healthcare services, its close ties with New Zealand, and ongoing public health initiatives. Estimates place overall life expectancy at approximately 76 to 77 years, with women typically outliving men by several years — female life expectancy averaging around 79 years and male life expectancy around 74 years. These figures are notable given the Cook Islands' small, dispersed population spread across 15 islands in the South Pacific. The country benefits significantly from its free association status with New Zealand, which allows Cook Islanders to access New Zealand's healthcare system and provides a pipeline of medical training and resources back to the islands. The main hospital, Rarotonga Hospital, serves as the primary referral center for the entire island group, while outer islands rely on smaller health clinics and regular visits from medical teams. Despite these advantages, the Cook Islands faces persistent health challenges that put pressure on longevity outcomes. Noncommunicable diseases — particularly cardiovascular disease, type 2 diabetes, and obesity — are leading causes of illness and premature death. The prevalence of obesity in the Cook Islands is among the highest in the world, a factor strongly linked to shifting dietary patterns, reduced physical activity, and the increased availability of imported processed foods. Emigration also complicates health statistics for the Cook Islands. A large portion of the indigenous population lives in New Zealand or Australia, meaning that health data collected locally reflects a smaller, sometimes older or more health-compromised resident population. This demographic reality can affect how life expectancy figures are interpreted and compared internationally. Public health authorities continue to prioritize programs targeting diet, physical activity, and chronic disease management. Regional organizations, including the Pacific Community and the World Health Organization's Western Pacific office, provide support for health surveillance and capacity building across the islands. Progress in reducing noncommunicable disease burdens is seen as the most significant lever for improving life expectancy outcomes in the coming decades.

What is the capital of the Cook Islands?
Avarua, located on the island of Rarotonga, serves as the capital and administrative center of the Cook Islands. It is the political, commercial, and cultural hub of the island group, housing the Parliament of the Cook Islands and most government offices. Formerly known as the Hervey Islands, the archipelago was renamed after British explorer Captain James Cook, who sighted the islands in 1770.
Where are the Cook Islands located?
The Cook Islands are situated in the South Pacific Ocean, in the region of Oceania, roughly midway between Hawaii and New Zealand. The archipelago consists of 15 islands spread across a vast expanse of ocean, divided into a northern group of low-lying atolls and a southern group of volcanic, more mountainous islands. Their remote oceanic position has profoundly shaped the islands' culture, economy, and political development.
What bodies of water surround the Cook Islands?
The Cook Islands are entirely surrounded by the South Pacific Ocean, with no land borders of any kind. The nearest neighbors include French Polynesia to the east, Samoa to the northwest, and Tonga to the west. New Zealand lies approximately 3,000 kilometers to the southwest and plays a central political and economic role, as the Cook Islands exist in free association with New Zealand since 1965.
What religion is practiced in the Cook Islands?
Christianity is by far the dominant religion in the Cook Islands, observed by approximately 55 percent of the population. Roman Catholicism accounts for roughly 17 percent of adherents, while the Seventh-day Adventist church represents about 8 percent. Protestant denominations, particularly the Cook Islands Christian Church, have deep historical roots dating to nineteenth-century missionary activity and remain central to community life and social identity across the islands.
What currency is used in the Cook Islands?
The Cook Islands use the NZD (New Zealand dollar) as their official currency, a direct reflection of the islands' close political and economic ties to New Zealand. This arrangement simplifies trade and financial transactions between the two territories. While the Cook Islands do issue their own commemorative coins, these hold legal tender status primarily as collectibles and the New Zealand dollar remains the currency in everyday circulation.
What languages are spoken in the Cook Islands?
English and Cook Islands Māori (also called Rarotongan) are both recognized as official languages. English is used in government, business, and education, while Cook Islands Māori is widely spoken in daily life and is central to the preservation of indigenous cultural identity. The Māori spoken in the Cook Islands is closely related to, though distinct from, the Māori language of New Zealand, reflecting shared Polynesian ancestry across the Pacific.
What is the geography of the Cook Islands like?
The Cook Islands comprise 15 islands divided into two main groups: the Northern Group of low-lying coral atolls and the Southern Group of rugged, volcanic islands, of which Rarotonga is the largest and most populous. Rarotonga features dramatic interior peaks rising steeply from narrow coastal plains, while the northern atolls are flat and only marginally above sea level, making them particularly vulnerable to rising seas. The total land area of the archipelago is relatively small despite being scattered across an enormous expanse of ocean.
What is the Cook Islands known for?
The Cook Islands are renowned for their traditional Polynesian dance and music, particularly the energetic ura dance form showcased at the annual Te Maeva Nui festival celebrating self-governance. The islands are also recognized for their black pearl cultivation, especially in the northern atolls, and for producing noni fruit and tropical agricultural exports. Additionally, the Cook Islands have become notable for issuing a distinctive national postage stamp collection prized by philatelists worldwide, and for the striking volcanic scenery of Rarotonga that draws eco-tourism visitors.
