For the first time, a New Zealand Army infantry platoon will be deployed to South Korea to work with local and United States Army forces.

The New Zealand Defence Force (NZDF) said 35 combat-ready soldiers will work with units from the Republic of Korea Armed Forces and US Army.

They'll undertake training and activities at the world-class Korea Combat Training Centre, the first NZ Army organisation to do so.

Land Component Commander Brigadier Jason Dyhrberg said over the next 90 days, they will undertake a range of infantry training activities with their South Korean and US counterparts.

"After three months, our troops will be more familiar with their counterparts' techniques and tactics and be better able to readily integrate into a coalition warfighting environment," Dyhrberg said.

"At the conclusion of their time on the Korean Peninsula, they will have been tested across a range of challenging scenarios and activities and be deemed combat ready under both the South Korean and US systems.

"We know the NZ Army produces world-class soldiers and officers. This deployment presents another great opportunity to showcase our people, to learn new skills and to develop greater levels of combat readiness alongside key international partners. I have no doubt that they will do us proud."

The NZDF has a long-standing commitment to supporting peace and stability on the Korean Peninsula and has been deploying personnel to the United Nations Command (UNC) and its Military Armistice Commission since 1998.

The New Zealand Defence Attaché to Korea, Colonel Rob Loftus, said the aim of the deployment was to foster cooperation and understanding between the three forces at the platoon level.

"This will provide our soldiers with a fantastic training opportunity to exercise with our military partners on the peninsula. They'll build relationships while putting themselves to the test.

"The platoon will also participate in several cultural and commemorative activities celebrating the 75th year anniversary of the United Nations Command, and Korean War battle anniversaries."

UNC Deputy Commander Canadian Army Lieutenant General Derek Macaulay said that as the UNC celebrated its 75th anniversary, it was honoured to welcome the NZ Army infantry unit.

"The platoon's presence here reflects New Zealand's steadfast commitment to UNC and to the enduring peace and stability of the Korean Peninsula. For over seven decades New Zealand has stood firm in support of the shared values we defend together.''

New Zealand contributed both naval and ground forces in support of UNC during the Korean War in the early 1950s, where more than 6000 New Zealanders served.

The platoon will remain on the Korean Peninsula until the end of October. Further joint training and mission rehearsal activities are being planned for 2026.
