New Zealand and the Cook Islands signed a major security declaration in Rarotonga on April 3 that ends a protracted political standoff, restores frozen funding and reasserts Wellington’s central role in the Pacific nation’s defence and security arrangements. The agreement, signed by New Zealand Foreign Minister Winston Peters and Cook Islands Prime Minister Mark Brown, will see New Zealand restore NZ$30 million (about US$17 million) in financial support that had been withheld during the dispute.
Peters said the declaration places “massive limitations” on a string of agreements the Cook Islands signed with China last year, and that it clarifies long-standing ambiguities around the partners’ constitutional relationship. “This declaration resolves this former ambiguity and provides clarity to both governments so that we can move forward focused on the future, not the past,” he told New Zealand media, adding the pact also signals to Beijing that there is a “special relationship” involving Tokelau, Niue and the Cook Islands that China did not fully acknowledge previously.
Under the new terms, the Cook Islands affirms New Zealand as its security “partner of choice” and agrees to prioritise Wellington for any security requests. The agreement requires the Cook Islands to provide “early and comprehensive notification” to New Zealand on security matters, including issues related to critical infrastructure such as ports and telecommunications. The text of the declaration, as described by officials, appears to give New Zealand effective veto power over third‑party agreements that could undermine the pact.
The declaration follows a breakdown in relations that began in late 2024 and escalated after the Cook Islands signed a series of pacts with China in 2025, including an infrastructure-focused strategic action plan. Wellington had publicly criticised those deals as having potential security implications and said the Cook Islands had failed to consult as required by their free-association arrangements. That row prompted a sharp exchange of public statements and the temporary suspension of some New Zealand assistance.
Prime Minister Mark Brown has consistently maintained the China agreements contained no security elements, and after signing the declaration he said he did not believe the pact with New Zealand would affect the Cook Islands’ agreements with other countries. Nonetheless, the new declaration formalises a requirement that the Cook Islands consults and notifies New Zealand on security-related matters—an outcome Wellington framed as restoring clarity on constitutional responsibilities.
The signing also comes amid other outstanding issues between the two partners, including Wellington’s concerns over a proposed new agreement with China and the Cook Islands’ plans to issue its own passport. For New Zealand, the declaration is being presented as a reset that protects mutual national security interests and re-establishes the consultation mechanisms that underpinned decades of cooperation. For the Cook Islands, leaders say the pact preserves sovereignty while reaffirming the practical security relationship with New Zealand.
China has reportedly pushed back on the announcement, calling for respect for Pacific countries’ sovereign choices, a reaction that underscores the broader strategic contest in the region. The declaration is likely to be watched closely across the Pacific for its implications on how small island states balance relationships with traditional partners and new external powers.
