Takapuwahia marae sits on the shores of Porirua Harbour. It falls beneath the mana of Ngāti Toa Rangātira iwi.
The wharenui, Toa Rangātira, was opened in 1982, replacing the previous wharenui, which had stood since 1901. The wharekai is called Parehounuku. The marae connects ancestrally to the waka Tainui, the maunga Whitireia, and the moana Raukawa.
