The Northern Maori by-election of 1980 was a by-election for the Northern Maori electorate during the 39th New Zealand Parliament. It was prompted by the resignation of Matiu Rata, a former member of the Labour Party who was establishing a new group, Mana Motuhake. Rata believed that contesting a by-election would give him a mandate for his change of allegiance. In the end, however, the seat was won by Bruce Gregory, the new Labour Party candidate.
