Once Were Warriors is a 1994 New Zealand tragic drama film based on New Zealand author Alan Duff's bestselling 1990 first novel. The film tells the story of the Heke family, an urban Māori whānau living in South Auckland, and their problems with poverty, alcoholism, and domestic violence, mostly brought on by the patriarch, Jake. It explores the detrimental effects of the colonisation of New Zealand suffered by Māori, and the survival of Māori culture against all odds.

Alan Duff is a New Zealand novelist and newspaper columnist. He is best known as the author of the novel Once Were Warriors (1990), which was made into a film of the same name in 1994.
