Foreign Minister Winston Peters said on 6 July 2026 that New Zealand learned of China's missile test only hours before it happened, and that the government is "deeply concerned" by it.

China's state news agency Xinhua reported that the People's Liberation Army Rocket Force conducted a submarine-launched test of a strategic missile, with a dummy warhead landing in designated Pacific waters. Xinhua called it a "routine" part of China's annual military training. Peters said the advance notice China gave was inadequate — the test occurred "within hours of informing us."

Peters said the missile landed inside the South Pacific Nuclear Free Zone, established by the Treaty of Rarotonga (which New Zealand signed and remains bound by). He said China's action "goes against the object and intent of that Treaty." New Zealand has long treated that zone as central to its Pacific security approach. "We have no interest in China using the South Pacific as a testing site for missile capability," Peters said. Wellington plans to consult Pacific partners about the development.

The Australia-Fiji context

The test took place on the same day Australia and Fiji signed what Australian ministers called a mutual defence treaty — the Australia-Fiji Ocean of Peace Alliance — in Suva. Prime Minister Christopher Luxon confirmed he had spoken with both the Australian and Fijian leaders about it. The Australian newspaper reported the missile test appeared to be a direct response to the alliance signing, though Beijing has not confirmed that and the Chinese Embassy did not respond to RNZ's request for comment.

The timing will affect Wellington's careful balance between its Five Eyes security commitments and its significant trade ties with China, whatever its cause may be.

A pattern emerges

Peters pointed to China's September 2024 test of an intercontinental ballistic missile — a rare, publicly announced launch into the Pacific — and said he was concerned about repetition. That earlier test drew criticism from Pacific Island nations, including Kiribati (a state aligned with China, which made its criticism unusual). The Pacific Small Island Developing States condemned that 2024 launch; the Arms Control Association recorded it as a PLA Rocket Force exercise announced by the Chinese Defence Ministry.

The US Department of Defense's 2025 report to Congress noted that China has a formal notification arrangement with Russia for certain ballistic missile and space launch tests. No equivalent arrangement exists with Pacific nations or New Zealand — a gap Peters' remarks indirectly highlight.

Two tests in under two years, both into the South Pacific, both described by Xinhua as routine training, both drawing regional protest. The pattern Peters named is there. What it means for how New Zealand deals with Beijing is harder to say. Wellington has generally moved more slowly than Australia to formally label China as a security concern, and Peters' language — "deeply concerned," breach of Treaty — is stronger than New Zealand typically uses toward Beijing. Whether this leads to formal diplomatic action or remains a public statement will be watched carefully in Parliament House and in Pacific capitals.
