The United States and the Cook Islands have launched a new initiative to collaborate on seabed mineral research and development. This announcement coincided with the Cook Islands’ 60th anniversary as a self-governing state in free association with New Zealand on August 4, 2025.
The partnership highlights a shared commitment to advancing marine science and promoting the responsible development of seabed resources. The Cook Islands controls one of the most mineral-rich Exclusive Economic Zones in the Pacific and is emerging as a key player in deep-sea exploration. U.S.-linked companies are already playing a leading role in mineral research within the Cook Islands’ waters.
This new cooperation will focus on rigorous scientific research, environmental best practices, and transparent governance of seabed resources. The United States has opened formal discussions to support Cook Islands-led research and data gathering to inform future exploration and development.
Diplomatic ties between the two countries were established in 2023. This new collaboration represents a step forward in mutual efforts to strengthen economic self-reliance and environmental stewardship in the Pacific region.
The political context adds further weight to the agreement. In June, New Zealand suspended millions of dollars in budgetary support to the Cook Islands as tensions grew over the island nation’s deepening relationship with China. The Cook Islands has increasingly looked to diversify its international partnerships.
Although self-governing, the Cook Islands remains in free association with New Zealand. Its citizens hold New Zealand passports and enjoy full rights to live, work, study, and access healthcare in New Zealand. King Charles III is the ceremonial head of state.
