About Tonga

Tonga, officially known as the Kingdom of Tonga, is an island country in Polynesia, part of Oceania. The country has 171 islands, of which 45 are inhabited. Its total surface area is about 750 km2 (290 sq mi), scattered over 700,000 km2 (270,000 sq mi) in the southern Pacific Ocean. As of September 2026, Tonga has a population of 103,291, 70% of whom live on the main island, Tongatapu. The country stretches approximately 800 km (500 mi; 430 nmi) north-south. It is surrounded by Fiji and Wallis and Futuna (France) to the northwest, Samoa to the northeast, New Caledonia (France) and Vanuatu to the west, Niue (the nearest foreign territory) to the east and Kermadec (New Zealand) to the southwest. Tonga is about 1,800 km (1,100 mi; 970 nmi) from New Zealand's North Island.

Tonga was first inhabited roughly 2,500 years ago by people who were a part of the Lapita culture, Polynesian settlers who gradually evolved a distinct and strong ethnic identity, language, and culture as the Tongan people. They quickly established a powerful footing across the South Pacific, and this period of Tongan expansionism and colonization is known as the Tuʻi Tonga Empire. From the rule of the first Tongan king, ʻAhoʻeitu, Tonga grew into a regional power. It was a thalassocracy that conquered and controlled unprecedented swathes of the Pacific, from parts of the Solomon Islands and the whole of New Caledonia and Fiji in the west to Samoa and Niue and even as far as parts of modern-day French Polynesia in the east. Tuʻi Tonga became renowned for its economic, ethnic, and cultural influence over the Pacific, which remained strong even after the Samoan revolution of the thirteenth century and Europeans' discovery of the islands in 1616.

From 1900 to 1970, Tonga had British protected-state status. The United Kingdom looked after Tonga's foreign affairs under a Treaty of Friendship, but Tonga never relinquished its sovereignty to any foreign power. In 2010, Tonga took a decisive step away from its traditional absolute monarchy and became a semi-constitutional monarchy, after legislative reforms paved the way for its first partial representative elections.

Tonga is a member of the Commonwealth of Nations, the United Nations, the Pacific Islands Forum, and the Alliance of Small Island States.

Geography and Climate of Tonga

The first humans arrived in Tonga around 1000 B.C. The islands’ politics were highly centralized under the Tu’i Tonga, or Tongan king, by A.D. 950, and by 1200, the Tu’i Tonga had expanded his influence throughout Polynesia and into Melanesia and Micronesia. The Tongan Empire began to decline in the 1300s, with civil wars, a military defeat to Samoa, and internal political strife. By the mid-1500s, some Tu’i Tongans were ethnic Samoan, and day-to-day administration of Tonga was transferred to a new position occupied by ethnic Tongans. Dutch navigators explored the islands in the 1600s, followed by the British in the 1770s, who named them the Friendly Islands. Between 1799 and 1852 Tonga went through a period of war and disorder. In the 1830s, a low-ranking chief from Ha’apai began to consolidate control over the islands and was crowned King George TUPOU I in 1845, establishing the only still-extant Polynesian monarchy. During TUPOU's reign (1845–93), Tonga became a unified and independent country with a modern constitution (1875), legal code, and administrative structure. In separate treaties, Germany (1876), Great Britain (1879), and the US (1888) recognized Tonga’s independence. His son and successor, King George TUPOU II, agreed to enter a protectorate agreement with the UK in 1900 after rival Tongan chiefs tried to overthrow him. As a protectorate, Tonga never completely lost its indigenous governance, but it did become more isolated and the social hierarchy became more stratified between a group of nobles and a large class of commoners. Today, about one third of parliamentary seats are reserved for nobles. Tonga regained full control of domestic and foreign affairs and became a fully independent nation within the Commonwealth in 1970. A pro-democracy movement gained steam in the early 2000s, led by ‘Akilisi POHIVA, and in 2006, riots broke out in Nuku’alofa to protest the lack of progress on reform. To appease the activists, in 2008, King George TUPOU V announced he was relinquishing most of his powers leading up to parliamentary elections in 2010 and henceforth most of the monarch’s governmental decisions, except those relating to the judiciary, were to be made in consultation with the prime minister. The 2010 Legislative Assembly was called Tonga’s first democratically elected Parliament. King George TUPOU V died in 2012 and was succeeded by his brother Crown Prince Tupouto‘a Lavaka who ruled as George TUPOU VI. In 2015, ‘Akalisi POHIVA became Tonga’s first non-noble prime minister.

Tonga in Depth

History

According to Tongan mythology, the demigod Maui drew up a group of islands from the ocean, first appearing Tongatapu, the Ha'apai Islands and Vava'u, integrating into what became modern-day Tonga.

An Austronesian-speaking group linked to what archaeologists call the Lapita culture covered from Island Melanesia to Samoa, and then on to inhabit Tonga sometime between 1500 and 1000 BC. Scholars still debate exactly when Tonga was first settled, but thorium dating confirms that settlers had arrived in the earliest known inhabited town, Nukuleka, by 888 BC, ± 8 years. Tonga's precontact history was shared via oral history, which was passed down from generation to generation.

Geography

Located in Oceania, Tonga is an archipelago in the South Pacific Ocean, directly south of Samoa and about two-thirds of the way from Hawaiʻi to New Zealand. Its 171 islands, 45 of them inhabited, are divided into three main groups – Vava'u, Ha'apai, and Tongatapu – and cover an 800-kilometre (500-mile; 430-nautical-mile)-long north–south line.

The largest island, Tongatapu, on which the capital city of Nukuʻalofa is located, covers 257 square kilometres (99 sq mi). Geologically, the Tongan islands are of two types: most have a limestone base formed from uplifted coral formations; others consist of limestone overlaying a volcanic base.

Economy

Tonga's economy is characterised by a large nonmonetary sector and a heavy dependence on remittances from the half of the country's population who live abroad (chiefly in Australia, New Zealand, and the United States). The royal family and the nobles dominate and largely own the monetary sector of the economy – particularly the telecommunications and satellite services. Tonga was named the sixth-most corrupt country in the world by Forbes magazine in 2008.

Tonga was ranked the 165th-safest investment destination in the world in the March 2011 Euromoney Country Risk rankings.

The manufacturing sector consists of handicrafts and a few other very small-scale industries, which contribute only about 5% of GDP.

Demographics

Over 70% of the 106,017 inhabitants live on its main island, Tongatapu. Although an increasing number of Tongans have moved into the only urban and commercial centre, Nukuʻalofa, where European and indigenous cultural and living patterns have blended, village life and kinship ties remain influential throughout the country. Despite emigration, Tonga grew in population from about 32,000 in the 1930s to more than 90,000 by 1976.

According to the government portal, Tongans, Polynesian by ethnicity with a mixture of Melanesian, represent more than 98% of the inhabitants. About 1.5% are mixed Tongans and the rest are European (the majority are British), mixed European, and other Pacific Islanders.

More about Tongatapu

Geography

The island is 257.03 square kilometres (99.24 square miles) (or 260.48 square kilometres (100.57 square miles) including neighbouring islands) and rather flat, as it is built of coral limestone. The island is covered with thick fertile soil consisting of volcanic ash from neighbouring volcanoes. At the steep coast of the south, heights reach an average of 35 metres (115 feet), and maximum 70 metres (230 feet), gradually decreasing towards the north.

North of the island are many small isolated islands and coral reefs which extend up to 7 kilometres (4.3 miles) from Tongatapu's shores. The almost completely closed Fanga'uta and Fangakakau Lagoons are important breeding grounds for birds and fish as they live within the mangroves growing around the lagoon's shores.

History

Tongatapu is known as having one of the highest concentration of archaeological remains in the Pacific. The earliest traces of Lapita pottery found in Tonga was from around 900–850 BC, 300 years after the first settlements in Tonga were established. Archaeologist David Burley discovered the pottery around the Fanga'uta Lagoon, 2,000 kilometres (1,200 miles) away from the Lapita pottery found at Santa Cruz in the Solomon Islands.

Tonga was always the seat of the Tuʻi Tonga Empire, but in an area of distances up to 1,000 kilometres (620 miles), it was often only a symbolic rule.

Climate

Tongatapu has a cooler climate than the rest of Tonga because it is the southernmost island group in the country. Consequently, fruit production is lower in Tongatapu than in the warmer northern islands.

Niue

Island · 221 km²

Niue is an island in Oceania (Polynesia), covering an estimated 221 km².

Niue is a self-governing island country in the South Pacific Ocean, in Polynesia, part of Oceania. Like the neighboring Cook Islands, it is in free association with New Zealand. Its population is predominantly Polynesian. As one of the world's largest coral islands, Niue is nicknamed "The Rock", which comes from the traditional name "Rock of Polynesia".

Niue's position is inside a triangle drawn between Tonga, Samoa, and the Cook Islands. It is 2,400 kilometres (1,500 mi) northeast of New Zealand, and 604 kilometres (375 mi) northeast of Tonga. Niue's land area is about 261.46 square kilometres (100.95 mi2) and its population was 1,689 at the Census in 2022.

The terrain of the island has two noticeable levels. The higher level is made up of a limestone cliff running along the coast, with a plateau in the centre of the island reaching approximately 60 metres (200 ft) above sea level. The lower level is a coastal terrace approximately 500 metres (1,600 ft) wide and about 25–27 metres (80–90 feet) high, which slopes down and meets the sea in small cliffs. A coral reef surrounds the island; the only major break in the reef is in the central western coast, close to the capital, Alofi.

More about Niue

Geography

Besides these, Albert Meyer Reef, 326 km (203 mi) southwest (20°53′S 172°19′W), almost 5 km (3.1 mi) long and wide, least depth 3 m (9.8 ft), is not officially claimed by Niue; further, the existence of Haymet Rocks (1,273 km (791 mi) east-southeast) is in doubt.

Niue is one of the world's largest coral islands. The terrain consists of steep limestone cliffs along the coast with a central plateau rising to about 60 metres (200 ft) above sea level. A coral reef surrounds the island, with the only major break in the reef being in the central western coast, close to the capital, Alofi. A number of limestone caves occur near the coast.

History

Archaeological evidence suggests that Polynesians from Samoa settled on Niue around 900 CE. Further settlers arrived from Tonga in the form of a war party in the 16th century, according to Niuean tradition.

Until the beginning of the 18th century, Niue appeared to have had no national government or single leader; chiefs and heads of families exercised authority over segments of the population. A succession of patu-iki (kings) ruled, beginning with Puni-mata. Tui-toga, who reigned from 1875 to 1887, was the first of the country's kings to adopt Christianity.

The first Europeans to sight Niue sailed under Captain James Cook in 1774. Cook made three attempts to land, but the inhabitants refused to grant permission to do so.

Demographics

The 2022 Niue Census of Population and Housing enumerated a population of 1,681, a decrease of around 2.2 per cent over the 2017 figure. Of this, 1,564 (93 per cent) considered Niue to be their place of usual residence, a decrease of 27 from 2017. Migration is a significant driver of population change, with 221 residents aged 5 and over not living in Niue five years prior to the census, suggesting substantial immigration. Niue has a population density of 6.0 inhabitants per square kilometre (16/sq mi). The majority of the population is located in the villages of Alofi South (25.2 per cent), Alofi North (11.1 per cent), Hakupu, and Tamakautoga (both 10.7 per cent).

According to the 2022 census, 1,153 (73.7 per cent) of residents identified of Niuean ethnicity.

Economy

Niue's gross domestic product (GDP) was NZ$17 million in 2003, or US$10 million at purchasing power parity. Its GDP had increased to US$24.9 million by 2016. Niue uses the New Zealand dollar.

The Niue Integrated Strategic Plan (NISP) is the national development plan, setting national priorities for development. Cyclone Heta set the island back about two years from its planned timeline to implement the NISP, since national efforts concentrated on recovery efforts. In 2008, Niue had yet to fully recover. After Heta, the government made a major commitment to rehabilitate and develop the private sector.
