French Polynesia is ramping up maritime surveillance in 2026, expanding enforcement and environmental monitoring across about 1.6 million square kilometers—roughly 617,000 square miles—of ocean in its exclusive economic zone.
The plan was laid out at a January 8, 2026 meeting of the Commission maritime mixte (CMM), a joint maritime commission co-chaired by France’s high commissioner (the French state’s top representative in the territory) and the president of French Polynesia. Officials reviewed decisions made at the previous CMM session in March 2024 and announced new resources set to arrive this year.
The message from the session was coordination: agencies involved in ocean protection, fisheries enforcement, maritime safety and recreational boating, and hydrography were told to produce real operational synergies—not just more meetings—backed by a separate steering body known as COSMer.
A 2024-to-2026 push, accelerated by the U.N. ocean conference
Between the March 2024 and January 2026 CMM sessions, several events reshaped the context for French Polynesia’s maritime protection agenda. The Summer 2024 Olympics, with sailing events held in Tahiti, brought unusual international attention to the area. Ifrecor also awarded its first “Toa Reef” trophies recognizing coral reef preservation.
More broadly, 2025 was declared an international “year of the sea,” culminating in the United Nations Ocean Conference (Unoc) in Nice. French Polynesia—administrator of one of the world’s largest exclusive economic zones—arrived with work already underway since 2024 that helped inform the positions presented at the U.N. gathering.
New coastal reserve squad and reinforcements for France’s biodiversity office
The most concrete announcements from the CMM focused on staffing and vessels. In 2026, new maritime resources will be assigned to French Polynesia, including the deployment of the Escouade de réserve côtière de Polynésie, a French Navy unit designed to cover coastal areas that offshore patrol ships cannot monitor continuously.
France’s Office français de la biodiversité (OFB), which handles biodiversity protection and fisheries controls, will also receive reinforcements, as will the state maritime affairs service. The three boosts are meant to address the fragmentation flagged at the previous CMM meeting. [1]
The logic, officials argued, is straightforward: across an area of 1.6 million square kilometers, no single actor can maintain sufficient presence. The Navy’s coastal reserve focuses on nearshore waters and reefs; the OFB covers biodiversity and fisheries enforcement; maritime affairs oversees mariner safety and recreational boating. The CMM is pressing them to stop operating in silos.
Why sovereignty and illegal fishing are driving the strategy
Behind the commission’s institutional language is a strategic reality France cannot ignore: French Polynesia’s exclusive economic zone is described as among the richest in fisheries and mineral resources in the Pacific. Pressure from illegal, unreported, and unregulated fishing is constant, and French Navy patrol vessels alone cannot cover such a vast area—one gap the coastal reserve squad is intended to partially fill.
Environmental surveillance also carries political weight. French Polynesia has promoted ocean protection on the international stage, and announcing stronger capabilities in 2026—the year after the Nice Unoc—serves as a signal as well as an operational upgrade.
COSMer: the missing day-to-day steering tool
COSMer is presented not as another layer of bureaucracy, but as the strategic steering body the CMM—meeting only periodically—cannot be on its own. Where the CMM sets direction and reviews progress, COSMer is tasked with continuity between sessions: tracking implementation, arbitrating budget priorities, and coordinating agencies day to day.
French Polynesia is one of the rare French territories where the national government and the local government share maritime responsibilities so explicitly. The CMM’s co-chair arrangement—between the high commissioner and the president of French Polynesia—reflects that split, and COSMer is intended to translate it into action over time.
The coming months will test whether the reinforcements announced in January are deployed on schedule. The French Navy, the OFB, and maritime affairs each operate on their own timelines, and coordination between Paris and Papeete has not always been smooth. The CMM set the framework; COSMer now has the job of making it work across 1.6 million square kilometers of ocean.
