Porangahau is a small township close to the Pacific Ocean coast of the southeastern North Island of New Zealand. It has a very small population. It is in the southernmost part of Hawke's Bay, 45 kilometres south of Waipukurau, and close to the mouth of the Porangahau River. There is a marae at Porangahau.
The township is six kilometres northeast[1] of an insubstantial hill noted for its substantial name: Taumatawhakatangihangakoauauotamateapokaiwhenuakitanatahu.[2]
