Veterans' Affairs Minister Craig Foss is in South Korea to mark the 65th anniversary of the Battle of Gapyeong.
Allied forces fought against Chinese troops to defend the town about 60km east of Seoul on April 24, 1951.
The 16th Field Regiment of the Royal Regiment of New Zealand Artillery played a significant role in the battle and was awarded the Republic of Korea's Presidential Citation.
Mr Foss will also attend an Anzac Day service in Seoul tomorrow.
"No matter where or when our military personnel served, they deserve to be honoured," Mr Foss says.
"While in Korea I will pay my respects to our fallen soldiers buried in the United Nations Memorial Cemetery in Busan and visit New Zealand Defence Force personnel deployed to the United Nations-controlled Demilitarised Zone (DMZ)."
He will present five New Zealand General Service Medals - Korea, and two New Zealand Operational Service Medals to military personnel finishing their deployment to the DMZ.
Mr Foss will also meet his South Korean counterpart, Minister of Patriots and Veterans Affairs Park Sungchoon.
