Ratana is a spiritual and cultural movement founded in the early 20th century by Ratana himself in New Zealand. It emphasizes the importance of community, faith, and social justice, aiming to uplift the Māori people and promote their rights and identity. The movement combines elements of Christianity with traditional Māori beliefs and practices. The Ratana Church, a key institution of the movement, serves as a place of worship and community gathering. It plays a significant role in Māori politics and social issues, advocating for the well-being of its members and the preservation of Māori culture.
