Cook Islander god of sea and fertility Tangaroa (Takaroa in South Island Māori dialect; cognate with Tagaloa in Sāmoan) is the great atua of the sea, lakes, rivers, and creatures that live within them, especially fish, in Māori mythology.
Ever since, Tangaroa has held a grudge with Tāne Mahuta, the atua of forests, because he offers refuge to his runaway children.
[3] The contention between Tangaroa and Tāne Mahuta, the father of birds, trees, and humans, is an indication that the Māori thought of the ocean and the land as opposed realms.
[4] The Kāi Tahu version of the origin of Takaroa maintains that he is the son of Temoretu, and that Papatūānuku is his wife.
[7]: 463 Tangaloa is one of the oldest Polynesian deities and in western Polynesia (for example, Samoa and Tonga) traditions has the status of supreme creator god.
