Qatar Airways will introduce its patented Qsuite business class service to its daily Auckland flights from June 1.
The long-awaited move has been welcomed by a travel agent as a "win-win" for passengers.
It is the industry's first-ever double bed available in business class, and can be set up as a private cabin for up to four people with privacy panels that stow away, a first in the industry.
The Qsuites are being retrofitted to existing aircraft as well as being installed in new widebody planes among the airline's 250-strong fleet.
Qatar flies a Boeing 777-200LR with an older style 2-2-2 seating configuration on the Auckland-Doha route, the airline's longest commercial flight.
