The Cook Islands Police Service (CIPS) is the police force of the Cook Islands. Among the Police Service's mandate is exercising sovereignty over the nation's 200 kilometre Exclusive Economic Zone. When the United Nations Convention on the Laws of the Seas extended maritime nations' economic zones Australia provided a patrol boat to the Cook Islands and patrol boats to 11 other fellow members of the Pacific Forum. The Cook Islands operates a Pacific-class patrol boat the CIPPB Te Kukupa commissioned in May 1989 which received a re-fit in 2015. Australia is currently building a larger and more capable Guardian-class patrol boat to replace the Te Kukupa for the police force.
