1. Voyagers sailing from Western Polynesia, exploring to the west on the prevailing easterly winds, settled on island in Southern Micronesia and Eastern Melanesia, now known a the Polynesian outliers. Samoan voyagers were ancestors of some Cook Island clans. From the 17th century into the 19th century. Tongans regularly visited Samoa, raided north through Tuvalu and into Micronesian Kiribati, and fought as mercenaries in Fiji.
2. About 1,000 years ago the leeward Thitian islands (Ra'iatea, Bora Bora, and Huahine) became a center of cultural change and great Mana from which adventurous high-status chiefs sailed to establish their rule in Tahiti and in the Hawaiian, Cook, Austral, and Tuamotu Islands. Some clans emigrated to New Zealand, which may have been rediscovered during this era. Hawaiian traditions begin with this era of conquest: those of earlier Polynesian inhabitants were not preserved.
