New Zealand is weighing whether to join a new Pacific defence alliance signed this week by Australia and Fiji, in a move that would tie the country into a formal mutual-defence pact for the first time in a generation and firmly place it inside a bloc that Beijing is likely to read as aimed squarely at China.
Australia and Fiji signed the treaty, known as the Ocean of Peace Alliance, in Suva on Monday. Under the agreement the two countries commit to cooperate and consult on security, and to act together to meet a common danger. In plain terms, each pledges to come to the other’s aid if either is attacked. The pact is Fiji’s first alliance of its kind and makes the Pacific nation Australia’s fourth formal ally, after the United States, New Zealand and Papua New Guinea.
Crucially, the treaty leaves the door open for other Pacific states to sign on, provided Australia and Fiji both agree. That clause is what has put a decision squarely in front of the New Zealand Government.
Prime Minister Christopher Luxon confirmed on Thursday that the Government would now discuss its interest in exploring membership with Canberra and Suva, with any final decision to be made by Cabinet before the usual parliamentary treaty process runs its course. He framed joining as the natural next step for a country that already shares deep military ties with both partners.
“We already work with both countries on how we can develop a safer region for all, so engaging with them on this alliance is logical,” Luxon said in a statement. He noted that New Zealand and Australia share a military alliance that “continues to go from strength to strength”, along with a strong and enduring relationship with Fiji. He also argued there was an advantage in not hanging back. “New Zealand being in early would be a good thing, because also you would have an ability to ultimately determine which other countries could join from across the Pacific,” he said.
Foreign Affairs Minister Winston Peters cast the alliance as an extension of relationships New Zealand has spent decades building rather than a break from them. “Elevating our long-standing relationship with Australia and Fiji, and other Pacific nations, to the next level through an alliance would mean we become even closer partners,” Peters said. He stressed that Pacific leaders have long insisted on Pacific-led responses to security in the region, and argued the new pact sat within that tradition rather than cutting across it.
The timing has given the decision an unmistakable edge. The Suva signing came only hours before China test-fired a long-range, nuclear-capable missile from a submarine into the South Pacific, a launch that drew a sharp condemnation from Wellington and rattled leaders across the region. Few in Canberra, Suva or Wellington believe the sequence was a coincidence, and the missile has become part of the backdrop to every conversation about the alliance.
Australia has been open that the treaty is part of a broader effort to counter China’s growing reach in the South Pacific, where Beijing has courted governments with loans, policing deals and infrastructure over the past decade. Waikato University law professor Al Gillespie said China would almost certainly object, describing the agreement as one that is pivoted at them, particularly if it grows into the foundation for a wider Pacific security bloc.
That is the balance the Government now has to strike. New Zealand has spent years presenting itself as an independent voice in the Pacific, comfortable working with Washington and Canberra while keeping its own trade and diplomatic channels to Beijing open. China remains New Zealand’s largest trading partner by a distance, and signing into an alliance widely understood as a response to Chinese assertiveness carries obvious commercial risk alongside the security calculation.
There is also the domestic politics of a decision that reaches well beyond the current term. A mutual-defence commitment is not the sort of thing a government can quietly reverse after an election, which is why the treaty process matters and why opposition parties will want a say. Labour, the Greens and Te PΔti MΔori have all historically been cautious about anything that looks like drawing New Zealand deeper into a great-power contest, and an alliance framed against China will test that instinct in an election year.
For now the Government has committed only to talking. No timeline has been set, and officials have been careful to describe the next phase as exploring interest rather than a done deal. But Luxon’s comments about the value of being in early suggest Wellington is leaning towards engagement rather than sitting on the sidelines while a new Pacific security order takes shape without it.
Defence and foreign policy rarely decide New Zealand elections, but the choices being made now about how closely to bind the country to Australia, Fiji and the wider Western alliance will shape the country’s place in the world for years.
