New Zealand and Cook Islands Strengthen Ties with Defense Pact

New Zealand and the Cook Islands have signed a significant defense and security pact, effectively easing over a year of diplomatic tension between the two nations. The agreement reaffirms New Zealand as the Cook Islands’ “partner of choice” in matters of defense and security.

Background to the Agreement

The diplomatic standoff began following a comprehensive strategic partnership between the Cook Islands and China in February 2025. Cook Islands Prime Minister Mark Brown initially declined to disclose the details of the agreement, raising concerns in Wellington about potential security implications. New Zealand, a long-standing ally and benefactor of the Cook Islands, subsequently froze millions of dollars in aid.

Addressing Security Concerns

The new declaration resolves “ambiguity” regarding the existing relationship between the two countries, according to New Zealand Foreign Minister Winston Peters. The pact is intended to address concerns that China might fill a security role in the region, a prospect that Wellington had feared.

Cook Islands’ Position

Cook Islands is a self-governing country in free association with New Zealand, benefiting from New Zealand’s military defense and allowing its citizens to live and work freely in New Zealand. Prime Minister Brown defended his initial decision not to disclose the details of the China pact, stating it wasn’t required under existing agreements with Wellington. He emphasized that the new agreement with New Zealand does not affect other existing pacts.

Resumption of Aid and Regional Context

With the signing of the new declaration on Thursday, aid previously frozen by New Zealand will be reinstated. The agreement comes as China actively courts Pacific Island nations with aid, loans, and deals, seeking to increase its influence in the strategically important South Pacific region. Many of these islands possess large and lucrative exclusive economic zones.

China’s Response

China responded to the pact by stating that its relationship with the Cook Islands “is not directed at any third party” and respects the autonomy of Pacific Island nations. Chinese Foreign Ministry spokesperson Mao Ning affirmed a willingness to deepen cooperation with the Cook Islands.

Strategic Importance and Historical Ties

Peters highlighted the increasingly complex strategic environment, noting that the relationship between New Zealand and the Cook Islands dates back to 1965. The close ties, including the fact that Cook Islanders hold New Zealand passports, contributed to the initial concerns regarding the China deal. A previous suggestion by Brown to create a separate Cook Islands passport was later shelved following a strong response from New Zealand.

Looking Ahead

Both leaders affirmed that New Zealand will be the Cook Islands’ “first port of call” regarding defense and security matters. The agreement covers areas such as deep sea mining, infrastructure, and educational scholarships, but does not contain explicit security elements.
