Pacific Defence Expansion
New Zealand Considers Joining Australia-Fiji Defence Pact to Enhance Pacific Security
Key Points
Fiji becomes Australia’s fourth formal ally, marking Fiji’s first-ever military alliance.
The Ocean of Peace Alliance allows other Pacific states to join, with admission contingent on Australia and Fiji’s agreement.
New Zealand currently has only one formal ally—Australia—though Australia is part of Five Eyes and a NATO partner, underscoring NZ’s potential move toward broader security ties.
The treaty commits its parties to cooperate and consult, and to act to meet common danger, signaling deeper defence and security cooperation if NZ joins.
New Zealand’s Defence Force privately warned that Beijing’s naval activity and ballistic missile tests could become a persistent feature in the Pacific, highlighting regional security concerns around the pact.
New Zealand is weighing whether to join the Ocean of Peace Alliance, a new mutual defence pact between Australia and Fiji that could reshape Pacific security. Prime Minister Christopher Luxon said he is open to joining, calling it a chance to "strengthen Pacific unity" and deepen defence ties with the region's closest partners, according to Perth Now.
The alliance was signed by Australian Prime Minister Anthony Albanese and Fijian Prime Minister Sitiveni Rabuka. It makes Fiji one of Australia's only four formal treaty allies — and marks Fiji's first-ever military alliance. The treaty commits members to consult each other and act together in the face of a common threat, 24 News HD reported.
What the Ocean of Peace Alliance Actually Does
The Ocean of Peace Alliance is a mutual defence treaty. Members must cooperate, consult, and come to each other's aid if any one of them is attacked. Right now, only Australia and Fiji are members. But the treaty explicitly allows other Pacific states to join — as long as both Australia and Fiji agree, according to Wellington Times.
For Fiji, joining marks a historic shift. The island nation has never before entered a formal military alliance. For Australia, Fiji becomes its fourth treaty ally. New Zealand currently has just one formal ally — Australia — so joining the pact would mark a significant expansion of its security commitments.
China's Missile Tests Fuel Urgency Behind the Pact
The alliance comes at a tense moment in the Pacific. New Zealand's Defence Force privately warned that China's ballistic missile tests and growing naval activity could become a "persistent feature" in the region, Perth Now reported. Beijing has been expanding its influence across Pacific island nations in recent years.
The pact is widely seen as a regional response to that pressure. By locking in formal defence commitments, Australia and Fiji aim to build a stronger, Pacific-led security framework. Supporters say New Zealand's membership would add further weight to that effort.
Luxon and Peters Back Joining, Cabinet Has Final Say
Prime Minister Luxon and Foreign Affairs Minister Winston Peters both voiced support for joining. Peters framed it as part of a Pacific-led approach to regional security. But neither has made a firm commitment. Any final decision must go through New Zealand's Cabinet and the parliamentary treaty process, according to Singleton Argus.
Discussions with Australia and Fiji would also need to happen before New Zealand could be admitted. Under the treaty's rules, both founding members must agree to let any new nation in. New Zealand already shares deep security ties with both countries, which supporters say makes the path to membership straightforward, Port News reported.
A Rare Shift in New Zealand's Cautious Alliance History
New Zealand has long kept its formal alliance commitments narrow. Australia is its only treaty ally, even though New Zealand is part of the Five Eyes intelligence network and Australia is a NATO partner. Joining the Ocean of Peace Alliance would represent a notable step toward broader security ties in the Pacific, according to 24 News HD.
The government has been careful to frame any potential membership in Pacific terms — not as a move against China. Still, the timing makes the strategic signal hard to miss. With Chinese naval ships and missiles appearing more often in Pacific waters, New Zealand faces growing pressure to define where it stands, Perth Now reported.
