TÃÂreha Te Moananui (died 19 December 1880) was a Paramount Chief of the NgÃÂti Kahungunu iwi, and a MÃÂori member of Parliament in New Zealand from 1868 to 1870.
Born between 1800 and 1810, TÃÂreha was the son of the great Chief Oneone of NgÃÂti Rangikamangungu and HÃÂmene of NgÃÂi Tà «hoe. He received the paramountcy and name of Te Moananui following the death of NgÃÂti Kahungunu leader Kurupà  Te Moananui in 1861.
TÃÂreha was known as 'Te Mokopuna a Tangaroa', this is due to his families close descent and association with Pania and the Ponaturi tribe who live in the sea. Because of this the ancestral Wharenui at Waiohiki is called Hau Te Ana Nui, which is also the name of his ancestor Tangaroa's house in the ocean.
TÃÂreha was one of four MÃÂori elected in 1868 for the new MÃÂori electorates in the New Zealand Parliament, and he was the first of the four to speak in Parliament. He represented the electorate of Eastern Maori from 1868 to 1870, when he retired.
He died on 19 December 1880, and his tangi and funeral took place at Waiohiki, near Taradale. He had two surviving children, sons Te Roera TÃÂreha (1850sâÂÂ1941) and Kurupà  TÃÂreha (1871âÂÂ1938).
