They also crown a Queen to represent her people for a year throughout Polynesia and on the world stage.

Through intimate character portraits, behind-the-curtain moments and heartfelt musical performances, “Te Pito o Te Henua” reveals the true meaning of Tāpati and the deep connections the Rapa Nui share with their lands and waters.
