The Hindu and Buddhist cultures in Indonesia gradually extended to Polynesia through tradesmen and preachers of Indonesia some of whom might have settled down in Polynesia and were called the Arii or the Aryans. Dr. E. S. Cragihill Handy describes the story of Polynesian culture as "a mere index to Indian history."

Author of the 'Ancient Voyagers in Polynesia' is of opinion that Polynesian ancestors came from the west through the waters between Buru and Yap to eastern New Guinea and the Melanesian island and thence to Polynesia by a slow succession of West-East voyage. 

The hypothesis of Indian contact with the Polynesians is strengthened by the discovery of the Easter Island scripts which closely resemble the scripts of the Indus Valley civilization.
