The Corps of Royal New Zealand Engineers is the administrative corps of the New Zealand Army responsible for military engineering. The role of the Engineers is to assist in maintaining friendly forces' mobility, deny freedom of movement to the enemy, and provide general engineering support. The corps has been involved in numerous conflicts over the course of its history including World War I, World War II, the Korean War, the Vietnam War and the war in Afghanistan. The corps consists of a single regiment, 2nd Engineer Regiment, primarily based at Linton Military Camp near Palmerston North.

Military engineering is loosely defined as the art, science, and practice of designing and building military works and maintaining lines of military transport and military communications. Military engineers are also responsible for logistics behind military tactics. Modern military engineering differs from civil engineering. In the 20th and 21st centuries, military engineering also includes CBRN defense and other engineering disciplines such as mechanical and electrical engineering techniques.
