The Air Force Museum of New Zealand, formerly called The Royal New Zealand Air Force Museum, is located at Wigram, the RNZAF's first operational base, in Christchurch, in the South Island of New Zealand. It opened on 1 April 1987 as part of the celebrations for the RNZAF's 50th anniversary, and is primarily a museum of the Royal New Zealand Air Force, its predecessor, the New Zealand Permanent Air Force and New Zealand squadrons of the Royal Air Force. The Air Force Museum of New Zealand's mission is to preserve and present the history of New Zealand military aviation for commemoration, learning, inspiration and enjoyment. The Museum holds the national collection of the Royal New Zealand Air Force. The collection includes objects covering the early days of New Zealand military aviation both prior to World War I and during this major conflict, the interwar years which saw the formation of the RNZAF in 1937, New Zealanders who fought in the RAF and in other Allied air forces during World War II, the RNZAF’s campaign in the Pacific, and the post-war period to the present day. The collection also includes objects from former enemy forces, aircraft, aircraft components, aircraft engines, large objects, textiles, art and memorabilia as well as an extensive paper and photographic archive.
