A new quad chairlift that will replace Whakapapa's Waterfall T-bar is to be installed this summer, while at Turoa the company has plans for a new express lift and cafe.
"These new lift projects will be supported with investment in increased snowmaking capacity and new chalet buildings on the upper slopes of both ski areas," said a spokesperson for RAL.
A new express quad chairlift opened on Whakapapa's lower field this winter.
Meanwhile, lifetime Mt Ruapehu lift passes are being offered for the first time in a decade.
The life passes cost $3950
and are available until October 10.
The lifetime pass price would buy around 42 days of skiing at the daily adult rate of $95.
A "life pass plus" is also available for purchase. It costs $5150 and can be transferred to another person within 10 years of purchase.
