Pacific Documentation - Lost World of The Pacific - Polynesian Islands Documentary
Polynesia is characterized by a small amount of land spread over a very large portion of the mid and southern Pacific Ocean. Most Polynesian islands and archipelagos, including the Hawaiian Islands and Samoa, are composed of volcanic islands built by hotspots. New Zealand, Norfolk Island, and Ouvéa, the Polynesian outlier near New Caledonia, are the unsubmerged portions of the largely sunken continent of Zealandia. Zealandia is believed to have mostly sunk by 23 m.y.a. and resurfaced geologically recently due to a change in the movements of the Pacific Plate in relation to the Indo-Australian plate, which served to uplift the New Zealand portion. At first, the Pacific plate was subducted under the Australian plate. The Alpine Fault that traverses the South Island is currently a transform fault while the convergent plate boundary from the North Island northwards is a subduction zone called the Kermadec-Tonga Subduction Zone. The volcanism associated with this subduction zone is the origin of the Kermadec and Tongan island archipelagos.
Out of about 117,000 or 118,000 square miles (300,000 or 310,000 km2) of land, over 103,000 square miles (270,000 km2) are within New Zealand; the Hawaiian archipelago comprises about half the remainder. The Zealandia continent has approximately 1,400,000 square miles (3,600,000 km2) of continental shelf. The oldest rocks in the region are found in New Zealand and are believed to be about 510 million years old. The oldest Polynesian rocks outside of Zealandia are to be found in the Hawaiian Emperor Seamount Chain, and are 80 million years old.
Geographic area
Polynesia is generally defined as the islands within the Polynesian Triangle, although there are some islands that are inhabited by Polynesian people situated outside the Polynesian Triangle. Geographically, the Polynesian Triangle is drawn by connecting the points of Hawaii, New Zealand and Easter Island. The other main island groups located within the Polynesian Triangle are Samoa, Tonga, the Cook Islands, Tuvalu, Tokelau, Niue, Wallis and Futuna and French Polynesia.
There are also small Polynesian settlements in Papua New Guinea, the Solomon Islands, the Caroline Islands, and in Vanuatu. An island group with strong Polynesian cultural traits outside of this great triangle is Rotuma, situated north of Fiji. The people of Rotuma have many common Polynesian traits but speak a non-Polynesian language. Some of the Lau Islands to the southeast of Fiji have strong historic and cultural links with Tonga.
However, in essence, Polynesia is a cultural term referring to one of the three parts of Oceania (the others being Micronesia and Melanesia). DNA studies suggest that the indigenous Pacific Islands population migrated from Taiwan thousands of years ago and dispersed throughout the region into three distinct cultural groups.

The following are the islands and island groups, either nations or overseas territories of former colonial powers, that are of native Polynesian culture or where archaeological evidence indicates Polynesian settlement in the past.[3] Some islands of Polynesian origin are outside the general triangle that geographically defines the region.
