Two New Zealand naval ships have sailed through the Taiwan Strait in a move Wellington described as routine, putting the strategically important waterway back in the spotlight as tensions over Taiwan continue to shape security dynamics across the Indo-Pacific.
The New Zealand Defence Force said the frigate Te Mana and replenishment vessel Aotearoa transited the strait on Sept. 18 as part of a three-month deployment in the Indo-Pacific. Prime Minister Christopher Luxon said the passage was conducted safely, professionally and in accordance with international law.
The transit is significant because China claims sovereignty and jurisdiction over the Taiwan Strait, while Taiwan and the United States regard the waterway as an international route. Beijing has rejected the characterization of the strait as international waters in the way Washington and Taipei describe it.
New Zealand does not maintain formal diplomatic relations with Taiwan, but the two sides maintain unofficial representative offices. Wellington has also continued to deepen its involvement in regional security and maritime activities while maintaining extensive economic ties with China.
Luxon said he was not expecting a backlash from Beijing over the latest voyage. China’s Defence Ministry had not immediately responded to requests for comment, while Chinese officials have previously criticized foreign military activities in waters Beijing considers subject to its jurisdiction.
The latest voyage also carries additional context because Aotearoa was reportedly monitored by Chinese forces during its previous Taiwan Strait transit in November 2025. A source cited in the reporting said Chinese ships and aircraft followed the vessel, with Chinese jets conducting simulated attacks during that earlier passage.
New Zealand is not alone in sending naval vessels through the strait. US warships make periodic transits, while countries including Canada and Britain have also conducted passages. Such operations are closely watched because the Taiwan Strait is both a major commercial shipping corridor and one of the most sensitive strategic waterways in East Asia.
The two New Zealand vessels are also expected to continue their wider Indo-Pacific deployment, including regional engagements and exercises. Their passage through the Taiwan Strait therefore comes amid a broader pattern of military and maritime activity by countries seeking to maintain operations across the region.
For Wellington, the voyage has been presented as a routine naval movement. But with competing claims over the Taiwan Strait and increasing military activity around Taiwan, even routine passages can carry wider strategic significance.
