New Zealand is considering joining the new defence alliance between Australia and Fiji. Prime Minister Christopher Luxon says the government will discuss possible membership before making a formal decision. New Zealand already maintains a close defence relationship with Australia and participates in the Five Eyes intelligence network, but it has traditionally taken a more cautious approach to formal military commitments. Supporters believe joining the alliance would strengthen Pacific-led security cooperation. Critics may question whether a new defence structure could increase regional tensions at a time when competition between China and Western countries is expanding across the South Pacific.
