Easter Island

It is unknown whether the takuturi were used, like the moai, for ancestor worship and mana accumulation.

An excerpt from the article 29 facts about Easter Island
There is a theory that these statues served the cult of the bird god (Tangata manu) that developed on Rapa Nui in the last period before Europeans arrived on the island. Thus, they would prove to be the youngest moai on the island.
