The Parties to the Nauru Agreement are Federated States of Micronesia, Kiribati, Marshall Islands, Nauru, Palau, Papua New Guinea, Solomon Islands and Tuvalu and often are referred to as the PNA.

Their 3rd Implementing Arrangement, adopted in 2008, follows a tradition of innovation by PNA leaders in developing new initiatives to manage tuna resources in the region. Many of the measures of the PNA were also adopted at the last meeting of the Western and Central Pacific Fisheries Commission such as the high seas pockets closure, controls on Fish Aggregating Devices (FADs) and the coverage of purse seine fishing vessels with observers.
