Air New Zealand has agreed to sell nearly 20% of its share in Virgin Australia to China’s Nanshan Group for approximately $193m.
Nanshan Group owns Chinese start-up carrier Qingdao Airlines.
The deal is yet to receive approval from Chinese regulators.
Air New Zealand chairman Tony Carter said in a statement: "We believe Nanshan Group will be a very strong, positive and complementary shareholder for Virgin Australia.
"The sale will allow Air New Zealand to focus on its own growth opportunities, while still continuing its long-standing alliance with Virgin Australia on the trans-tasman network."
Air New Zealand currently owns a 25.9% stake in Virgin Australia and is mulling over options on the rest of its Virgin Australia shares.
