Some anthropologists believe there is an association between Pulotu and Burotu, the term for the paradise underworld in the Fijian religion.
The Burotu in Lau no longer existed within the first 800 years AD when the Tu’i Pulotu Empire was at its height of supremacy in the Pacific.
It may make sense that the Tui Pulotu was originally from Moturiki if we look around the Fiji islands during the BC Lapita era.
The only island that can match the meaning of the word Pulotu, where most archaeological discoveries for the so-called Lapita civilizations, with the reconstructed woman's face, plus the 6500-year-old petroglyph stone encrypted with concentric circles were found, was in Moturiki, Lomaiviti.
It is there that some believed that Tongan culture and its people developed and evolved out of the ancient Austronesian/Lapita culture (c. 1600 BCE - c. 500 BCE) that migrated from the South East Asian islands through Taiwan, the Philippines, Malaysia, Indonesia, Papua New Guinea, Solomon Islands, New Caledonia, Vanuatu, Micronesia and Fiji in about 8000 BC.
