Sustainable Winegrowing New Zealand (SWNZ) is an industry-wide certification programme led by New Zealand Winegrowers.
In the mid-1990’s, after considerable testing, the industry launched a holistic vineyard programme, which has since become known as Sustainable Winegrowing New Zealand.
The Sustainable Winegrowing New Zealand (SWNZ) programme is based on continuous improvement and adherence to recommendations and guidelines issued by the International Organisation of Vine and Wine (OIV).
SWNZ was developed to:
- Provide 'best practice' model of environmental practices in the vineyard and winery
- Guarantee better quality assurance from the vineyard, right through to the bottle
- Address consumer concerns regarding products, while respecting the environment
SWNZ ensures members meet international standards for sustainability practices while helping the environment, businesses and local communities to thrive. The programme was introduced commercially in 1997 and adopted by grape growers across the country’s winegrowing regions.
Sustainable winery certification standards were established in 2002 and adopted by New Zealand wineries, closing the circle on the industry’s sustainability commitment. In 2016, 98% of New Zealand’s vineyard producing area was Sustainable Winegrowing NZ certified, with another 7% operating under recognised certified organic programmes.
