The Air Force is to replace its ageing maintenance training aircraft at a cost of $6 million.
It has bought four second-hand, twin-engined Mitsubishi aircraft and six Seasprite helicopters from the United States.
The aircraft, which are not intended to fly, will be used to train Air Force mechanics and technicians at Marlborough's Woodbourne airbase.
The Air Force says the turbo-prop training aids replace piston-engined aircraft dating from the 1960s.
The 10 aircraft will be delivered over the next four months.
