ʻAta is a depopulated island in the far southern end of the Tonga archipelago, situated approximately 160 kilometres south-southwest of Tongatapu. It is distinct from ʻAtā, an uninhabited, low coral island in the string of small atolls along the Piha passage along the north side of Tongatapu. An unrelated traditional chiefly title from Kolovai is "Ata". …ʻAta is a depopulated island in the far southern end of the Tonga archipelago, situated approximately 160 kilometres south-southwest of Tongatapu.
