Powerful Breakthroughs for 2025 in New Zealand Wine Industry Sustainability
The NZW Sustainability Report 2025 is a testament to the ingenuity, commitment, and leadership demonstrated by winegrowers across the island nation. Let’s explore the key focus areas and headline achievements shaping the landscape:
- Carbon footprint reduction in wineries and vineyards
- Sustainable packaging in wine industry
- Non-chemical pest management vineyards
- Comprehensive biosecurity in New Zealand vineyards
- Innovative disease resistance & genetic research
1. Carbon Footprint Reduction in Wineries and Vineyards
We have seen a significant surge in efforts to reduce carbon emissions across the New Zealand wine industry. According to the latest data, 68% of wineries (a 10% increase from 2022) and 56% of vineyards (up from 41% in 2022) now participate in specialized initiatives targeting the reduction of their environmental footprint.
Some of the most effective measures adopted include:
- Switching to renewable energy sources in wine production processes
- Implementing efficient energy management systems
- Optimizing water use and resource efficiency
- Cutting waste generation and diverting materials from landfills
This collective effort has driven a 30% reduction in sector-wide emissions since 2010—a feat positioning us at the forefront of sustainable winegrowing New Zealand.

2. Eco-Packaging and Sustainable Packaging in the Wine Industry
Packaging has historically contributed significantly to the wine industry’s carbon footprint. Our collective shift toward sustainable packaging in wine industry settings is evident in these report findings:
- Lightweight glass bottles: 63% of wineries use these, up from 55% in 2022.
- Improved packaging efficiency: Now at 32% of wineries, growing from 23%.
- Recyclable or biodegradable packaging: Adopted by 68% of wineries, rising sharply from 55%.
By adopting circular packaging and reducing the weight of glass bottles, we cut downstream transport emissions and decrease resource extraction impact. Sustainable packaging not only reduces environmental damage but caters to evolving consumer preferences for eco-friendly products.

3. Innovative Pest Management and Biosecurity in New Zealand Vineyards
A near-universal embrace of non-chemical pest management vineyards sets New Zealand apart in global wine production. 99% of vineyards report using non-chemical methods, emphasizing biological strategies, habitat management, and careful monitoring to minimize agrochemical reliance.
Additionally, 100% of agrichemical applications are now recorded in the NZW’s database to support robust benchmark reporting and analysis. This gives us the data needed for targeted, continuous improvement in pest and disease management.
Looking forward, from the 2025/26 season, biosecurity planning will be mandatory for all SWNZ-certified vineyards—a crucial step given New Zealand’s geographic isolation and clean climate, which help protect the country’s grapevines from many global pests and diseases.
If biosecurity remains a primary concern on your farm, Farmonaut offers powerful large-scale farm management solutions with real-time monitoring and disease alerts.
Key Methods in Non-Chemical Pest Management
- Habitat creation for beneficial insects
- Row management to encourage pest-resilient microclimates
- Canopy management and pruning
- Use of sheep for weed and grass management, reducing herbicide needs
4. Advanced Technologies in Sustainable Winegrowing
Embracing cutting-edge technology, we are seeing transformational results across New Zealand’s wine regions. Here are major highlights:
- UV-C Light for Powdery Mildew Control in vineyards: The ‘A Lighter Programme’—advanced UV-C applications in vineyards—show promise in controlling powdery mildew sustainably, reducing reliance on fungicides.
- Biosecurity Planning via SWNZ: Strategic planning prevents invasive pests and diseases from entering and spreading in New Zealand’s isolated winegrowing regions.
- Bragato Research Institute NZ wine: Development of over 12,000 new Kiwi Sauvignon Blanc variants aims for resilience—drought/frost tolerance and inherent pest & disease resistance.
Each innovation leverages a scientific approach—blending research, data, and field trials to future-proof both product quality and sustainability.
Powdery Mildew Control in Vineyards: UV-C Innovation
A persistent challenge for vineyards is powdery mildew, a fungus that damages grapes and affects yields globally. Conventionally, control relies on repeated fungicide applications. Now, New Zealand’s government-agricultural venture deploys UV-C treatments—a solution that is chemical-free, precise, and scalable. Early trials suggest this approach dramatically lowers fungicide dependence and supports SWNZ’s biosecurity framework by discouraging resistance development.
Bragato Research Institute & Kiwi Sauvignon Blanc Development
Through the Bragato Research Institute NZ wine and its trials, our growers are actively developing 12,000+ new Kiwi Sauvignon Blanc variants. Selection targets key traits:
- Drought tolerance
- Frost resilience in changing climates
- Natural resistance to regional pests and diseases
- Maintaining New Zealand’s reputation for vibrant, distinct Sauvignon Blanc wines
This programme will form the backbone of disease and climate adaptation strategies, ensuring long-term sustainability.
5. Supporting Sustainable Employment Practices
Sustainability is holistic—it’s not just about environmental progress but also about people. 65% of vineyards and 67% of wineries now voluntarily comply with the New Zealand wine industry’s Code of Conduct for employment. This ensures every worker is treated with fairness and dignity, building resilient communities alongside a resilient industry.
