Air New Zealand will opt for Boeing aircraft for its next generation of widebody planes, according to Reuters.
The airline is likely to go with modified 787 Dreamliners to replace its eight 777-200s, as tipped by the Herald.
Citing unidentified sources, Reuters said Boeing had won an 18-month battle with Airbus to supply the planes.
In an interview with the Herald published on Saturday, Air New Zealand's chief financial officer Jeff McDowall the choice was down to a new version of the Dreamliner - which the airline has flown since 2014 - and the Airbus A350XWB.
It is one of the biggest calls made by the airline in more than 15 years but a spokeswoman said today that it hadn't made any announcement on the order.
