The tension is personal for Prime Minister Mark Brown, who is seeking a fifth consecutive term with his Cook Islands Party. In an exclusive interview with the Guardian days before the vote, Brown defended his four-year tenure, which saw the country push back against what he described as a reliance on a single partner. Central to his defense is the strategic partnership with Beijing, signed in 2025, a move that sparked a severe diplomatic rift with New Zealand, the Cook Islands’ traditional ally under a “free association” relationship dating to 1965.
Wellington’s reaction was swift and sharp. New Zealand temporarily halted millions in aid, accusing Rarotonga of a lack of transparency in its dealings with China. Prime Minister Christopher Luxon stressed the expectation of transparent consultation on matters touching defense and security. Brown rejected the characterization of his government’s actions as secretive, calling the New Zealand response “patronising.” He argued that establishing clear defense boundaries with New Zealand allows the Cook Islands to freely pursue economic relationships elsewhere without compromising security ties. “In matters of security and defence, our partner is New Zealand,” Brown stated, noting that this clarity has allayed fears about the relationship.
However, the diplomatic fallout has left a mark on the domestic political landscape. Teariki Heather, leader of the Cook Islands United Party, organized a public protest against the China partnership last year. She argues that Brown’s lack of initial transparency upset the people, emphasizing that humility is central to Cook Islander identity and that the relationship with New Zealand has been “set in concrete” for decades. “What prime minister Mark Brown did has upset the people. It is not the way to act,” Heather said. A poll conducted by Cook Islands News suggests the election will be a close race, with the governing Cook Islands Party facing a fragmented field of 63 candidates for the 24 seats.
Underpinning this diplomatic maneuvering is the economic reality of a nation that has suffered significant shocks. When Brown took office in 2020, the country was reeling from the pandemic, which decimated tourism—a sector accounting for roughly 70% of GDP. Brown claims the economy is now the strongest in its history, citing year-on-year growth exceeding 10% and a halving of the debt accumulated in 2022. Yet, the nation remains vulnerable to global energy shocks. Recent fuel price spikes resulting from conflicts in the Middle East led to unstable supply and increased costs, prompting the administration to establish a fund to absorb extreme swings in energy prices.
The strategic value of the Cook Islands extends beyond diplomacy to the seabed itself. The country’s exclusive economic zone covers nearly 2 million square kilometers, containing an estimated 6.7 billion metric tons of polymetallic nodules. These deposits hold roughly 20 million metric tons of cobalt, alongside manganese, nickel, and copper—critical minerals for batteries, advanced manufacturing, and defense technologies. This resource potential has drawn heightened interest from the United States, which established a non-binding framework for cooperation on critical minerals with the Cook Islands in February. This framework covers research, exploration, investment, and processing.
Brown insists that no mining is currently taking place and that there will be no extraction until impacts on the marine environment are fully understood. “The exploration phase is still being undertaken,” he said, noting that ongoing research is attracting interest from global institutes. Environmental groups and some regional leaders warn that seabed extraction could cause irreversible damage to fragile ecosystems, a concern that adds a layer of complexity to the government’s economic diversification strategy.
The geopolitical stakes are high, as noted by the Royal United Services Institute (RUSI), which describes the China-Cook Islands partnership as part of a broader transformation of Pacific geopolitics. The competition is no longer just about aid or infrastructure; it is about access to the maritime domain and critical resources. While the Chinese state-run Global Times frames the debate as Western powers treating Pacific islands as arenas for competition, the Cook Islands government maintains that its engagement with Beijing is intended to complement, not replace, its established ties with New Zealand, Australia, and the US.
As the 18th Parliament dissolves and the 24 single-member constituencies prepare for their vote, the outcome will signal how this small nation intends to balance its sovereignty. Whether the voters view the broadened partnerships with China, India, South Korea, Japan, and the US as a necessary path to economic resilience or a dangerous departure from traditional alliances, the Cook Islands remains a pivotal player in the Pacific’s shifting geopolitical order. The next government will inherit a complex landscape where every diplomatic handshake carries weight far beyond the island’s shores.
