Tonga is divided into 5 administrative divisions, which constitute the country's sole level of subnational administration. These divisions serve as the primary organizational units for local governance and public administration throughout the kingdom. Each division typically corresponds to major island groups in the Tongan archipelago and facilitates the delivery of government services, maintains public infrastructure, and oversees local administrative matters. The divisions function as intermediary structures between the central government in Nuku'alofa and individual villages or districts, helping coordinate policies related to education, health services, and community development. This administrative framework reflects Tonga's geographic dispersion across multiple islands and enables more efficient governance across the archipelago.
