"His work and pro-bono experience has meant Ross has had many years of developing excellent stakeholder relationships across a broad range of interest groups" Mr Gribben said
"Ross' experience makes him an ideal person to execute the board's clear aims and aspirations for our ski areas: high quality tourism products that increasingly operate year-round," he said.
Mr Mazey announced his intention to retire in May following 30 years of dedicated service to stewardship of the mountain and an ongoing commitment to improving the RAL offering.
"With the appointment of Ross, the board is pleased to have Dave continuing on a consultancy basis to assist with the hand-over, complete the planning and consenting processes for some of the significant infrastructure projects scheduled for the short to medium term," Mr Gribben said.
"In addition Dave will continue to work with Ngati Rangi, Uenuku and DOC to ensure the renewal of the Turoa licence which expires in 2022, and work with Ngati Tuwharetoa, managing the relationship agreement to reflect our shared values, focusing on preserving and protecting the cultural values and environment within the park."
Mr Gribben said RAL has significant upgrade projects underway which include: the consenting and installation of three new lifts at Whakapapa, a quad chairlift to replace the Waterfall T Bar; gondola out of the base area; an express chairlift to replace the Valley and Knoll Ridge T Bars; plus, at Turoa the upgrade of the Movenpick Chairlift to an express lift. 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.
