The New Zealand Tunnelling Company was a tunnel warfare unit of the Royal New Zealand Engineers during World War I which specialised in sapping and mining. The tunnelling companies were occupied in offensive and defensive mining involving the placing and maintaining of mines under enemy lines, as well as other underground work such as the construction of deep dugouts for troop accommodation, the digging of subways, saps, cable trenches and underground chambers for signals and medical services. The unit is particularly known for its role at Carrière Wellington and during the Battle of Arras.

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.
