Mangamutu is a small settlement, on the western outskirts of Pahiatua, in the North Island of New Zealand. The Wairarapa Line runs through the area, with the Pahiatua railway station in the settlement.[1] The settlement was the birthplace of former New Zealand Prime Minister Sir Keith Holyoake.[2]
Mangamutu takes its name from the nearby Mangamutu stream. It is a Māori phrase meaning finished stream from the words manga meaning stream and mutu meaning finished.
Mangamutu is home to a significant Fonterra dairy factory. The factory was originally commissioned by the Tui Dairy Company in 1976; Tui merged with Hāwera-based Kiwi Dairies in 1996, who in turn merged with the New Zealand Dairy Group in 2001 to form Fonterra.[3]
