In MÃÂori tradition, Tokomaru was one of the great ocean-going canoes that were used in the migrations that settled New Zealand. It was commanded by Manaia. His brother-in-law had originally owned the canoe. When Manaia's wife was raped by a group of men, he slew them, including the chief Tupenu. Killing his brother-in-law, he took the Tokomaru and set sail with his family for New Zealand. Landing at Whangaparaoa, they finally settled at Taranaki. Te ÃÂti Awa, NgÃÂti Mutunga, NgÃÂti Tama iwi trace their ancestry back to Tokomaru.
In 1938, New Zealand Government Railways (NZR) introduced the Standard class railcars, naming one "Tokomaru" after the MÃÂori migration canoe.
