A hapū is a sub-tribe or clan within the Māori social structure in New Zealand. It is a group of related families who share a common ancestor and work together for mutual support and protection. Hapū play a vital role in Māori culture, often managing local resources and making decisions for their community. Each hapū is part of a larger iwi, or tribe, and has its own unique identity, traditions, and leadership. The connections within a hapū are strengthened through shared history, language, and customs, which help maintain the cultural heritage of the Māori people.
