The 29th Battalion was an infantry battalion of the New Zealand 3rd Division, raised for service during the Second World War. Serving in the Pacific, the battalion mainly undertook garrison duties and labouring tasks in Fiji and New Caledonia, but saw brief combat against the Japanese in the Treasury Islands in late 1943. In late 1944, the battalion returned to New Zealand and was broken up to provide reinforcements for the New Zealand 2nd Division in Italy. It was eventually disbanded in January 1945.
