Between 1942 and 1946, the Royal New Zealand Air Force (RNZAF) operated 297 P-40's (although four were destroyed before being officially brought on strength) of various models (E, K, L, M, N). The aircraft were assigned to Nos 14, 15, 16, 17, 18, 19 and 20 Fighter Squadrons, and No's 2 and 4 (F) OTU. Nos 14 thru 19 Squadrons flew P40's in the Pacific, carrying out offensive and defensive fighter operations, bomber escort, and dive-bombing duties. A total of 99 Japanese aircraft were destroyed in the air, with 14 probables recorded. 20 P-40's were lost in combat, and a further 152 in accidents in New Zealand and overseas.
The P-40 began to be replaced in front line duties by F4U-1A's from 1944. The remainder were sold for scrap in 1948.
