Polynesian Navigation & Settlement of the Pacific

Polynesian navigation of the Pacific Ocean and its settlement began thousands of years ago. The inhabitants of the Pacific islands had been voyaging across vast expanses of ocean water sailing in double canoes or outriggers using nothing more than their knowledge of the stars and observations of sea and wind patterns to guide them.

The Pacific Ocean is one-third of the earth's surface and its remote islands were the last to be reached by humans. These islands are scattered across an ocean that covers 165.25 million square kilometres (63.8 million square miles). The ancestors of the Polynesians, the Lapita people, set out from Taiwan and settled Remote Oceania between 1100-900 BCE, although there is evidence of Lapita settlements in the Bismarck Archipelago as early as 2000 BCE. The Lapita and their ancestors were skilled seafarers who memorised navigational instructions and passed their knowledge down through folklore, cultural heroes, and simple oral stories.

The Polynesian's highly developed navigation system impressed the first European explorers of the Pacific and since then scholars have been debating several questions:

was the migration and settlement of the Pacific islands and into Remote Oceania accidental or intentional?

what were the specific maritime and navigational skills of these ancient seafarers?

why has a large body of indigenous navigational knowledge been lost and what can be done to preserve what remains?

what type of sailing vessels and sails were used to cross an open ocean?

Ancient Voyaging & Settlement of the Pacific

By at least 10,000 years ago, humans had migrated to most of the habitable lands that could be reached on foot. What remained was the last frontier – the myriad islands of the Pacific Ocean that required boat technology and navigational methods be developed that were capable of long-range ocean voyaging. Near Oceania, which consists of mainland New Guinea and its surrounding islands, the Bismarck Archipelago, the Admiralty Islands, and the Solomon Islands was settled in an out-of-Africa migration c. 50,000 years ago during the Pleistocene period. These first settlers of the Pacific are the ancestors of Melanesians and Australian Aboriginals. The small distances between the islands in Near Oceania meant that people could island-hop using rudimentary ocean-going craft.

The so-called second wave of migration into Remote Oceania has been an intensely debated scholarly topic. Remote Oceania is the islands to the east of the Solomon Islands group such as Vanuatu, Fiji, Tonga, Aotearoa (New Zealand), Society Islands, Easter Island, and the Marquesas. What is debated is the origins of the first people who settled in this region between 1500-1300 BCE, although there is general agreement that the ancestral homeland was Taiwan. A dissenting view has been that of Norwegian adventurer Thor Heyerdahl (1914-2002 CE) who set out in 1947 CE on a balsa raft called Kon-Tiki that he hoped would prove a South American origin for Pacific islanders. Archaeological and DNA evidence, however, points strongly to a southeast Asian origin and seafarers who spoke a related group of languages known as Austronesian who reached Fiji in 1300 BCE and Samoa c. 1100 BCE. All modern Polynesian languages belong to the Austronesian language family.

Collectively, these people are called the Lapita and were the ancestors of the Polynesians, including Maori, although archaeologists use the term Lapita Cultural Complex because the Lapita were not a homogenous group. They were, however, skilled seafarers who introduced outriggers and double canoes, which made longer voyages across the Pacific possible, and their distinctive pottery – Lapita ware – appeared in the Bismarck Archipelago as early as 2000 BCE. Lapita pottery included bowls and dishes with complex geometric patterns impressed into clay by small toothed stamps.

Between c. 1100-900 BCE, there was a rapid expansion of Lapita culture in a south-east direction across the Pacific, and this raises the question of intentional migration.
