Four Andovers were withdrawn from service in 1997 and the remainder in 1998. They were replaced by leased
Beechcraft Model B200 King Airs. The leasing of aircraft was a new venture for the RNZAF, with a commercial contractor providing maintenance support to the aircraft on site. The workload for the aircraft is multi-engine conversion training of pilots qualified to fly single engine aircraft, continuation training for multi-engine qualified pilots and a limited VIP transport role around New Zealand. The squadron returned to Ohakea in January 2002. It continued operating four B200 King Airs as part of the flying training wing. In 2018 the RNZAF leased four
King Air 350 aircraft to replace the King Air 200 aircraft operated by No.42 Squadron, with the first aircraft arriving at Ohakea in April 2018. In July 2020, New Zealand
Minister of Defence Ron Mark welcomed the delivery of the fourth and final King Air 350 to Ohakea, bringing No.42 Squadron back up to full operating capability. Two of the four aircraft are permanently fitted with sensor suites, allowing for training of aircrew officers as well as multi-engine pilot training. Previously RNZAF aircrew officers were trained in
Australia under an agreement with the
RAAF. ==Commanding Officers==
