Exporters and travellers would benefit from strengthened connections with Emirates' international network, including 30 points in Europe, as well as the growing Middle East region and Africa.
"The Master Coordination Agreement sets the stage for Qantas and Emirates to share services across the Tasman, allowing Emirates to offer Queenstown and Wellington as tourism destinations accessible on their network," Mr Brownlee said.
Trans-Tasman competition would be maintained through existing carriers on the route and the threat of entry by new carriers, he said.
Under conditions imposed by the Australian Competition and Consumer Commission airlines are required to maintain at least their pre-alliancecapacity, subject to a review to consider whether increases in the minimum required capacity are warranted.
"Competition between strong home carriers is important for the Australasian aviation market, and this alliance will ensure competition is retained, while opening the door to additional benefits for New Zealand," said Mr Brownlee.
