iwi refers to the Māori tribes or clans in New Zealand, representing the largest social units within Māori society. Each iwi is made up of smaller groups called hapū, which are further divided into whānau or families. Iwi play a crucial role in preserving Māori culture, language, and traditions. Iwi have their own distinct histories, customs, and governance structures. They often engage in activities related to land management, resource rights, and community development. Many iwi are involved in treaty settlements with the New Zealand government to address historical grievances and promote economic growth for their members.
