A December 2025 report from the New Zealand Defence Force and Ministry of Foreign Affairs confirms that China is expanding its maritime security presence throughout the South Pacific. The document highlights increased naval activity in the Philippine Sea and the Tasman Sea, noting that certain Chinese military exercises have forced commercial airlines to alter their flight paths.
How is China expanding its presence in the Pacific?
According to a 15-page report submitted to New Zealand Prime Minister Christopher Luxon, Beijing is pursuing a “progressive expansion” of its maritime security influence. This trend has developed over the last decade, as the world’s second-largest economy seeks to extend its reach into a region traditionally dominated by United States military presence.
The document, which was authored by the New Zealand Defence Force and the Ministry of Foreign Affairs, notes that Wellington is maintaining “operational surveillance” on Chinese vessels. New Zealand officials are currently working in close coordination with Australian counterparts to monitor these movements.
While Beijing maintains that its military objectives are peaceful, the report identifies a pattern of increasing deployment. This includes a significant movement of warships in the Philippine Sea and specific operations in the Tasman Sea, the body of water situated between Australia and New Zealand.
The report mentions the use of “space support ships.” These specialized vessels are designed to monitor satellite activity, rocket launches, and intercontinental missile movements.
What impact do these naval deployments have on civilian activity?
Naval exercises conducted by the Chinese military have directly affected international commercial travel. The New Zealand report states that a deployment of three Chinese warships in the Tasman Sea in February 2025 did not adhere to international best practices regarding notification.
As a result of these maneuvers, several airlines were forced to modify their flight itineraries to avoid the exercise zones. The report notes that while the deployment was conducted in accordance with the United Nations Convention on the Law of the Sea, the lack of proper communication created operational challenges for civilian aviation.
This tension highlights a growing friction point between military maneuvers and the maintenance of safe, predictable international transit corridors in the Pacific.
Comparing Regional Maritime Incidents
The report allows for a comparison between two distinct periods of Chinese naval activity in the region:
| Event Period | Location | Reported Impact |
|---|---|---|
| February 2025 | Tasman Sea | Forced airline route changes due to notification issues. |
| December 2025 | Philippine Sea | Consistent with a decade-long maritime expansion. |
What kind of ships is China using for these missions?
The Chinese navy is deploying a diverse fleet that serves both military and humanitarian roles. According to the findings shared with AFP, the range of vessels includes:
- Hospital Ships: Used for medical support and maritime assistance.
- Large Amphibious Vessels: Intended to support humanitarian aid and disaster relief operations.
- Space Support Ships: Tasked with tracking orbital and missile-related activities.
- General Warships: Involved in active maritime security and presence operations.
The use of dual-purpose vessels—those capable of both humanitarian relief and military support—is a central component of China’s strategy to increase its footprint in the South Pacific.
When monitoring maritime security, look for the deployment of “dual-use” assets. Ships that provide humanitarian aid can often serve as logistical anchors for broader military presence.
