This Kaupapa Māori Research writing inquiry explores the (mis)appropriation of haka and the social media video-sharing platform YouTube in that (mis)appropriation. The article examines the specific case of a group of Latter-day Saint missionaries in Wangarratta, Australia, who wrote and performed an English- language haka that the author finds violent and offensive. The article outlines Aileen Moreton-Robertson’s White Possessive doctrine in relation to the Church and white patriarchal salvation. Haka’s cultural background and appropriation are explained. Theoretical explanations of collective and cultural memory and YouTube as a social media platform and cultural archive follow. The author highlights YouTube grey literature sources on haka cultural (mis)appropriation. The 2006 case study “missionary haka” video is critiqued and analysed. Case study issues are discussed. The Church’s history of racial discrimination and violence and its religious aetiology of skin colour make this video ”misappropriated,” according to research. This performance uses haka to promote white and religious supremacy and the idea that you must be white and/or religious to be fully human. This message helps the LDS Church mission of possessing Indigenous souls and remaining the “true religion”.
