Kaj Olaf Mortensen arrived in New Zealand in late 1940 onboard the four-masted barque Pamir. He enlisted in the RNZAF in 1943, but seems to have served in the Army as well.
Kaj Olaf Mortensen was born on 13 December 1915 in Grenaa in Denmark. He was the son of painter Viggo Mortensen and Martha Mortensen (née Jensen).
Mortensen almost certainly arrived in New Zealand in December 1940 onboard the then Finnish owned four-masted barque Pamir. He was a mess-boy. In any event, Mortensen deserted the ship while it was berthed at New Plymouth. On 19 February 1941, a warrant for his arrest was published in the New Zealand Police Gazette. He was sentenced one year’s probation for ship-desertion on 14 March 1941.
Pamir left New Zealand on 20 February 1941 for the Seychelles. When it returned in August 1941, it was seized as a prize of war by the New Zealand government. Mortensen married Morva Joan Mason on 18 October 1941. Mortensen was naturalised in New Zealand on 21 September 1944.
The Danish Association in New Zealand donated an ambulance to RNZAF at a small ceremony in Auckland on 10 October 1943. Mortensen was one of a small number of Danes in service participated in the ceremony.
Information on Mortensen’s service is scarce and a bit confusing. He seems to have enlisted in the RNZAF in 1943 (NZ4311434) but also served the Army (808599). He served in 22 Battalion, which operated in Italy in 1944.
