Mangaroa is a rural settlement just outside of Upper Hutt, situated in the lower North Island of New Zealand. It includes lifestyle blocks and farms surrounded by hills, which are usually covered by a dusting of snow during the winter. The former Mangaroa Railway Station is located at Mangaroa. Mangaroa has its own indie rock radio station, andHow.FM. The New Zealand Ministry for Culture and Heritage gives a translation of "long stream" for Mangaroa.
