Real Journeys chief executive Richard Lauder said the company was excited to be bringing Cardrona back into Kiwi hands.
"Cardrona is a fantastic brand and is undoubtedly one of the best ski fields in New Zealand, it's only fitting that it has a proud and local Kiwi owner."
The resort will be run as a separate entity but Lauder said there would be opportunities, particularly for seasonal staff, to shift between the organisations.
"There are some great synergies between Real Journeys and Cardrona from both a brand and operational point of view," Mr Lauder said.
"For the first time in around 60 years Real Journeys is actually looking forward to winter."
Real Journeys Chairman Ian Fitzgerald said the purchase was about Real Journeys diversifying and growing its business.
"Cardrona is a quality operation underpinned by the value of its assets, the acquisition of which will be positive for both companies," says Fitzgerald.
Real Journeys was named preferred bidder for Cardrona Alpine Resort in May 2013, with due diligence and shareholder approval from both boards required in order to complete the sale.
Real Journeys is a family-owned South Island business. It operates the TSS Earnslaw and Walter Peak High Country Farm in Queenstown, cruises in Milford and Doubtful Sounds, the Te Anau Glow-worm Caves, day walks on the Milford Track and Stewart Island ferry and tour services.
The company also has stakes in Black Cat Cruises, Queenstown Rafting and Milford Sound Flights.
