The battalion fought in the Greek, North African and Italian campaigns, during which it earned a formidable reputation as an extremely effective fighting force. It was also the most decorated New Zealand battalion of the war. Following the end of hostilities, the battalion contributed a contingent of personnel to serve in Japan as part of the British Commonwealth Occupation Force, before it was disbanded in January 1946. Wiremu Te Tau Huata was a well known officer from Ngāti Kahungunu, having served as the Māori Battalion's military chaplain. By 1946 only a small percentage of land in the Ngāti Kahungunu region had been retained by Māori, and the traditional agrarian communities at the core of Māori society were beginning to break down as returned servicemen found employment and settled in urban areas, such as Wairoa, Napier, Hastings, and Masterton. By the year 1966, 70% of Māori men (throughout New Zealand in general) were now working in urban employment centres, particularly freezing works, sawmills, the transport industry (including road maintenance), the construction industry, and various types of factory work. In Hawke's Bay, thousands of Māori worked at the Whakatu and Tomoana freezing works sites, near Hastings. However the regional economy and well-being of the Māori community was profoundly impacted when both plants closed; Whakatu in 1986 and Tomoana in 1994. In 1988, Te Rūnanganui o Ngāti Kahungunu Incorporated was established as a centralised organisation responsible for iwi development, but it went into receivership in 1994. The organisation re-emerged with a new constitution in 1996 under the name Ngāti Kahungunu Iwi Incorporated (NKII). An election was held in 1997, resulting in the establishment of an elected board of trustees and a new mandate to govern iwi development. Elections are held every three years, and all adults with a whakapapa link to a hapū of Ngāti Kahungunu are eligible to vote. The chairperson of the board of trustees usually represents the iwi in political affairs. In accordance with the constitution of Ngāti Kahungunu Iwi Inc, the board of trustees consists of ten "tangata whenua" representatives:   The board employs a General Manager and staff, which oversees the operational affairs of the iwi organisation. General Managers have included Labour member of parliament Meka Whaitiri.
