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.

The film was directed by Lee Tamahori, written by Riwia Brown, and stars Rena Owen, Temuera Morrison and Cliff Curtis. It became the highest-grossing film of all-time in New Zealand, and has won numerous awards.
