Air New Zealand will use the GEnx-1B engine to power its eight Boeing 787-10 Dreamliner aircraft with option up to 20 aircraft.
The firm engine order is valued at more than $480 million list price. Aircraft delivery will begin in 2022.
Air New Zealand and GE also agreed to a multi-year TrueChoice services agreement to cover the maintenance, repair and overhaul of the GEnx engines.
“Today’s news is incredibly exciting for our business and our customers as we continue to invest in the most innovative, sustainable and comfortable aircraft on the market and deliver on our commitment to grow our business sustainably,” said Air New Zealand chief executive officer Christopher Luxon. “In connecting New Zealand with the world, we naturally offer a high proportion of long-haul flights, and these state-of-the-art aircraft will ensure we continue to operate one of the world’s youngest and most efficient jet fleets.”
