paragraph_text: Pacific Islands
  
  Polynesian, Melanesian and Micronesian peoples originally populated many of the present-day Pacific Island countries in the Oceania region over the course of thousands of years. European, American, Chilean and Japanese colonial expansion in the Pacific brought many of these areas under non-Indigenous administration, mainly during the 19th century. During the 20th century, several of these former colonies gained independence and nation-states formed under local control. However, various peoples have put forward claims for Indigenous recognition where their islands are still under external administration; examples include the Chamorros of Guam and the Northern Marianas, and the Marshallese of the Marshall Islands. Some islands remain under administration from Paris, Washington, London or Wellington.
  
  The remains of at least 25 miniature humans, who lived between 1,000 and 3,000 years ago, were recently found on the islands of Palau in Micronesia.
  
  In most parts of Oceania, Indigenous peoples outnumber the descendants of colonists. Exceptions include Australia, New Zealand and Hawaii. In New Zealand, based on various factors including census data and self-identification, the proportion of full or part Māori of the population on 30 June 2021 was estimated to be 17%. Māori developed from Polynesian people who settled in New Zealand after migrations from other Pacific islands, probably in the 13th century. Many leaders of Māori nations (iwi) signed a written agreement with the British Crown in 1840, known as the Treaty of Waitangi.
  
  A majority of the Papua New Guinea population is Indigenous, with more than 700 different nationalities recognized in a total population of 8 million. The country's constitution and key statutes identify traditional or custom-based practices and land tenure, and explicitly set out to promote the viability of these traditional societies within the modern state. However, conflicts and disputes concerning land use and resource rights continue between indigenous groups, the government, and corporate entities.
