Snowmaking is rapidly becoming the new normal for New Zealand ski fields
Shorter winters, warmer temperatures, and unpredictable snowfalls mean operators can’t rely solely on natural snow to run a full season. In an industry where season length and reliability determine financial success, snowmaking has shifted from a backup option to the backbone of operations.
From Queenstown’s big-name resorts to the volcanic slopes of Mt Ruapehu, snowmaking machines are working earlier and harder than ever before. The goal is simple: guarantee a skiable product regardless of what nature delivers. This technology allows operators to open on target dates, keep trails covered during warm spells, and cater to a growing market that expects consistent conditions.
What’s happening on New Zealand’s slopes today
In the South Island, snowmaking has become an essential part of how ski fields open and operate. Coronet Peak now runs one of the largest snowmaking networks in the Southern Hemisphere, allowing it to open early in the season and even offer night skiing well into the shoulder months. Porters was the pioneer, installing Canterbury’s first snowmaking system back in 1991, a decision that has since proved critical to keeping the mountain open during lean years. Fields like Cardrona and The Remarkables have also invested heavily, expanding their systems to guarantee snow coverage during key Australian holiday periods, when visitors expect reliable skiing no matter the weather.
In the North Island, snowmaking is just as vital – and in some cases, the only way to get the lifts spinning early. At Whakapapa, the snow guns in Happy Valley were fired up in May 2025, letting the beginners’ area open weeks before the first decent natural snowfall. Tūroa followed a similar path, opening Alpine Meadow in late May solely on machine-made snow. For both mountains, artificial coverage has become the tool that bridges the gap until winter fully arrives.
The environmental equation
Snowmaking does use water and energy, but ski fields are increasingly finding ways to manage the impact. Many now run their snow guns on renewable electricity, recycle water through storage ponds, and use newer machines that produce more snow with less energy. Advances in technology mean operators can target snow exactly where it’s needed, reducing waste and extending coverage.
Sustainable power in action
Some of New Zealand’s major ski areas – Coronet Peak, The Remarkables, and Mt Hutt, are leading the way by using 100 % certified renewable electricity through a partnership with Meridian Energy. This not only powers efficient snowmaking but also means zero Scope 2 emissions from electricity use.
The Remarkables is aiming for carbon neutrality by 2030, while Mt Hutt couples energy-efficient snow grooming with conservation efforts on the mountain. It’s a reminder that ski fields can embrace innovation while protecting the landscapes that make them special.
The outlook for the future
For many New Zealand ski fields, snowmaking isn’t just part of the playbook—it is the playbook. As climate patterns continue to shift, its role will only grow. But it’s clear that operators are not just embracing the technology – they’re innovating responsibly. From renewable power to precision snow coverage, they’re proving it’s possible to keep our mountains white and green.
Snowmaking Coverage by Ski Field - Winter 2025
| Ski Field | Snowmaking Details |
|---|---|
| Coronet Peak | Over 200 fixed and portable snow guns, covering ~100% of cruisable terrain. Supports early-season openings and night skiing. |
| Cardrona | Snowmaking supplements its ~2.9 m average annual snowfall, maintaining a consistent, skiable base through the season. |
| Porters | First Canterbury field to introduce snowmaking (1991). Modernised system keeps main pistes open during dry spells. |
| Whakapapa | Expanded snowmaking now covers Rockgarden and Waterfall slopes, improving reliability in low-snow periods. |
| Tūroa | Automated, high-tech snowmaking across key volcanic terrain. Often the only way to open early and keep slopes skiable. |
| Mt Hutt | Energy-efficient snow guns with reservoir support; helps deliver one of NZ’s longest seasons. Powered by 100% renewable electricity. |
