The 14th Brigade was a formation of the New Zealand Military Forces, which served during the Second World War as part of the 2nd New Zealand Expeditionary Force. Eventually forming part of the 3rd Division, the brigade served in the Pacific Ocean theatre of the war. Raised in December 1941, the brigade undertook garrison duties in Fiji before being relieved by US troops in mid-1942. After this, it took part in two combat actions against Japanese forces in 1943–1944: the Land Battle of Vella Lavella and the Battle of the Green Islands. In mid-1944, the brigade was broken up to return manpower to New Zealand industry and to meet the reinforcement needs of the 2nd Division in Italy.

The 3rd New Zealand Division was a division of the New Zealand Military Forces. Formed in 1942, it saw action against the Japanese in the Pacific Ocean Areas during the Second World War. The division saw action in the Solomon Islands campaign during 1943–1944, during which it undertook landings on Vella Lavella, the Treasury Islands and the Green Islands. Due to manpower shortages, for most of its existence the division consisted of only two infantry brigades in addition to support personnel, with its third brigade being disbanded shortly after formation. In 1944, manpower shortages in the New Zealand economy became acute led to the disbandment of the division. The majority of its manpower was returned to civilian employment, although around 4,000 men were sent to Italy to reinforce the 2nd Division, seeing further action before the end of the war in May 1945.
