Trinity Hill is proud to certified by Sustainable Winegrowing New Zealand.

Trinity Hill Winery is a part of the Sustainable Winegrowing New Zealand programme, a proactive management system that facilitates high-quality wine production using sustainable practices in the vineyard and winery.

Our efforts focus on adherence to, and continuous improvement of, Sustainable Winegrowing New Zealand standards – biodiversity, soil, water and air, energy, chemicals, by-products, people and business practices.

Increasing biological diversity, improving soil health, controlling pests, diseases and weeds using the most natural, cultural and biological methods available improves the health of our vineyards and land.

Using water economically and efficiently, measuring and reducing harmful emissions, reducing energy use, chemical inputs and waste by-products minimises our environmental footprint.

Promoting the development of a safe workplace and adopting ethical and socially responsible employment and business practices protects the well-being of our employees.

Continuously improving in these areas allows us to preserve our most valuable assets – our land and people – while having the lowest possible impact on the environment and human health.

At Trinity Hill, we intend to leave the land in a better state than when we found it.


Sustainable Winegrowing New Zealand:

Sustainable Winegrowing New Zealand certification programme (SWNZ) is an industry-wide certification programme led by New Zealand Winegrowers.

Sustainable Winegrowing NZ™ is widely recognised as a world-leading sustainability programme and was one of the first to be established in the international wine industry in 1995. SWNZ launched in 1995, as a programme based on continuous improvement and adherence to standards that ensures members meet international guidelines for sustainability practices in the vineyard and winery.

The programme was elected by grape growers across the country, followed by wineries with the establishment of sustainable winery certification standards in 2002.

The certification process:

To be SWNZ certified, all members must complete annual submissions and undergo regular on-site audits conducted by an independent verification company. Annual submissions are made through an online questionnaire covering off impacts across the industry’s six focus areas, which are Soil, Water, Plant Protection, Waste, People and more recently Climate Change.

Vineyard members must also submit a full spray diary annually, which documents all agrichemical applications made to the vineyard that season. Spray diaries are processed for compliance to ensure that only approved products have been used and specific rules of use have been adhered to.
