The question to owner NZSki is one of several in the fast-track panel's request for more information on the company’s fast-track application for the project.
NZSki, which lodged the application with the Environmental Protection Authority on May 20, responded to the request on Wednesday.
Referring to research published in 2012, it said the evidence supported the conclusion that expanding into the Doolans Basin’s ‘‘more resilient’’ terrain, combined with snowmaking technology, would enable the skifield to ‘‘continue to provide reliable snow activities for future generations to enjoy’’.
In the information request, Doc said NZSki’s application appeared to assume the Doolans Basin was not affected by climate change.
The company had not provided enough information about how its proposal was consistent with a ‘‘precautionary approach to developing a ski area in the face of climate change’’.
That included the likely longevity of the ski area in the face of climate change, and the costs of land remediation and facility removal should it stop operating.
Climate change data and an assessment supporting the expansion, for a proposed term of 40 years, was absent, it said.
In its response, NZSki said research published in 2012 found climate change would reduce natural snowfall across New Zealand, with the biggest impact occurring at lower altitudes.
However, it also found high-altitude ski areas were ‘‘comparatively well positioned to retain viable snow conditions into the long term, particularly when supported by technological intervention’’.
Long-term reliability of snow could be gained by expanding into the Doolans Basin.
‘‘It’s elevation, southerly aspect, and natural snow catchment benefits contribute to strong natural snow retention.
‘‘Collectively, these factors significantly enhance the resilience of the ski area in the face of a changing climate.’’
NZSki’s long-term snowfall records showed it had successfully operated in a highly variable snow environment for decades.
‘‘This operational experience, combined with ongoing investment in infrastructure and adaptive technologies, provides confidence in NZSki’s ability to respond effectively to future climatic variability.’’
If approved, the expansion would increase The Remarkables’ terrain from 449ha to 711ha, making it the largest skifield in the country.
Estimated to cost $150 million, the four-year project would include the installation of a 2.7km-long gondola and the construction of a new hospitality building and other facilities.
