Air New Zealand will operate a B787-9 to Honolulu from May 10.
The Dreamliner will replace the B767-300s that are currently rostered on to the four-times weekly route.
The switch represents an increase in capacity of almost 20 per cent.
ANZ will also move the current Sunday return service to Fridays.
From May 10, on Tuesdays, Thursdays, Fridays and Saturdays, the outbound flight will depart Auckland at 2055, arriving in Honolulu at 0730 the same day.
On Tuesdays, Thursdays and Fridays the return leg will leave Hawaii at 0940 and land in Auckland at 1635 the next day. On Saturdays, it will depart Honolulu at 1000 and land in New Zealand at 1700 the next day.
A fifth weekly service on Mondays will operate between July 4 and 26.
Cam Wallace, ANZ’s chief sales and commercial officer, said: “We’re looking forward to taking the 787-9 Dreamliner to Honolulu – not only will the aircraft allow us to deliver a significant capacity increase on the route but we’ll also be able to improve the experience our customers have on board with new inflight product, including our award-winning Economy Skycouch and Premium Economy product which offers greater space and comfort.”
ANZ took delivery of its first B787-9 Dreamliner in summer 2014 (see news, July 2014).
