Plural policing has become a key focus in critical policing and security scholarship, with growing acknowledgement that policing practices involve multiple actors and diverse institutional forms. While much of the recent interest in plural policing has been prompted by the global growth of private security, plural policing in the Pacific Islands has long been evident in the co-existence of state-based police organisations operating nationally, and traditional or customary policing forms operating at local levels in most of these countries and territories. This chapter examines the plural character of Pacific policing in the context of historical and more recent processes of pluralisation, including the expanding domains of private and transnational policing, highlighting the deepening entanglement and interdependency between these various policing forms. The geographic focus is on the independent Melanesian countries, the region’s most populous, socially diverse, and challenging policing environments.
