New Zealand and Cook Islands Sign Defence Pact, Resolve Aid Dispute
New Zealand and the Cook Islands have formally signed a defence and security declaration, bringing an end to a year-long diplomatic disagreement that saw New Zealand freeze financial assistance to the Pacific nation. The agreement, inked by New Zealand's Foreign Affairs Minister Winston Peters and Cook Islands Prime Minister Mark Brown in Rarotonga, aims to forge a renewed foundation for their relationship of free association and includes provisions for the restoration of New Zealand's annual funding.
Background to the Dispute
The Cook Islands has been a self-governing nation in free association with New Zealand since 1965, inheriting the relationship from its status as a New Zealand colony since 1901. Its approximately 17,000 citizens hold New Zealand citizenship, and both nations have standing obligations to consult on defence and security, with New Zealand constitutionally responsible for the Cook Islands' defence.
Diplomatic tensions flared in February 2025 after the Cook Islands entered into strategic partnership agreements with China. These agreements encompassed deep-sea mining, regional cooperation, economic issues, and infrastructure investment. New Zealand expressed considerable concern regarding a perceived lack of transparency around these deals, noting they represented the Cook Islands' first significant agreements outside its traditional partners, New Zealand and Australia. This development quickly raised alarms in Wellington about China's increasing influence in the Pacific region.
"In response, New Zealand, the primary funder for the Cook Islands, suspended millions of dollars in aid."
Cook Islands Prime Minister Mark Brown described New Zealand's action as "patronising" and "inconsistent with modern partnership." New Zealand's Foreign Affairs Minister Winston Peters acknowledged that the two governments had grappled with "serious disagreements" since late 2024.
The New Declaration
The new defence and security declaration, signed on a recent Thursday, mandates both nations to act in good faith and consult on all defence and security matters. Key provisions of the agreement include:
- Affirming New Zealand as the Cook Islands' security "partner of choice."
- Requiring the Cook Islands to prioritize New Zealand for support on security issues, particularly those related to critical infrastructure like ports and telecommunications.
- Mandating the Cook Islands to provide "early and comprehensive notification" to New Zealand on security matters.
- New Zealand has secured provisions that appear to grant it effective veto power over any agreements with "third parties" that could undermine the declaration.
Minister Peters stated that the declaration aims to "set a course together for the future" and provide clarity on the relationship, especially given the increasingly complex strategic environment since their free association began in 1965. He underscored the importance of clear communication between New Zealand, the Cook Islands, and third parties regarding their special relationship and mutual responsibilities in defence and security.
Prime Minister Brown affirmed the agreement is about "moving forward" and building a "new foundation built on clarity, on mutual acknowledgement and on the shared belief that two nations, different in size but equal in dignity, can build something genuinely worth investing in."
Restoration of Financial Aid
Following the signing of the declaration, New Zealand confirmed it would immediately resume its annual funding support to the Cook Islands. The reinstated financial assistance totals approximately NZ$30 million (US$25 million). Minister Peters indicated that the normalization of all aspects of the relationship would proceed following a mutually satisfactory understanding of their partnership's foundations.
Impact on China Agreements
Statements from both leaders offered differing perspectives on the declaration's impact on the Cook Islands' existing agreements with China.
Prime Minister Brown maintained that his nation's agreements with China were unrelated to security and stated that the new defence pact with New Zealand would not impact pacts with other countries.
However, Minister Peters indicated that the China deals are now "no longer a concern" for New Zealand, stating that the declaration resolves "former ambiguity" and allows both governments to focus on future cooperation.
He also informed New Zealand media that the Chinese pacts with the Cook Islands now have "massive limitations" to protect the national security of both New Zealand and the Cook Islands. Peters added that this agreement sends a clear message to the Chinese government about the special relationship New Zealand shares with Tokelau, Niue, and the Cook Islands.
Anna Powles, from Massey University, commented that the declaration clarifies ambiguities and confirms expectations regarding the Cook Islands' obligations across defence and security matters. She noted it positions New Zealand as the primary defence and security partner and ensures consultation on issues impacting national security, including critical infrastructure, while also acknowledging the Cook Islands' evolving identity.
