But the mountain's High Noon Express chairlift is not likely to be ready until the end of July after a tower on the 1.4km-long, six-seater chairlift buckled when the towers and cables were de-iced on Monday.
Mr Smith said the head of the tower was badly damaged and repairs would cost up to $100,000.
The $13 million lift was opened in 2007, although it was out of action for the first few days after a massive ice build-up automatically shut down the machinery.
Mr Smith said the top of the field, which the High Noon Express serviced normally, was not skiable for the first two weeks of the season anyway but a southerly storm, due early next week, would have brought enough snow to allow it to open.
He said Whakapapa was due to open on June 26.
Its new cafe facilities, replacing the cafe that was burned to the ground by an arsonist last year, should be completed by late next month.
Last year 453,000 people visited Turoa and Whakapapa with 30,000 of those from Australia.
