Air New Zealand will add two more Boeing 787-9 Dreamliner to its fleet.
This will take the number of Dreamliners to 12 by the end of 2018.
Air New Zealand last week added its third 787 to its fleet.
The airline's chief executive Christopher Luxon announced the fleet investment at an event in Sydney today.
"his investment is possible as a result of our strong commercial results. As the airline's commercial performance continues to improve, we are focussed on reinvesting our profits directly back into the business on products, services and fleet to further enhance the customer experience and to ensure the business remains strong and competitive."
