The 37th Battalion was an infantry battalion of the New Zealand Military Forces, which served during the Second World War. Attached to the 14th Brigade, New Zealand 3rd Division, the battalion was formed in late 1941 and saw service in the Pacific against the Japanese. They were initially used for garrison duties on Fiji and New Caledonia before being committed to the fighting in the Solomon Islands in 1943. Returned to New Zealand in late 1944, the battalion was disbanded in early 1945 as part of a partial demobilisation of New Zealand forces. Many of its personnel returned to civilian employment while others were sent to Italy as reinforcements for the New Zealand 2nd Division. The battalion was awarded four battle honours for its various engagements during the war.

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.
