Sustainable Winegrowing New Zealand is the national organisation encouraging and promoting sustainable wine-growing in New Zealand. In 2018 around 97% of New Zealand wine producers were accredited members of SWNZ (pronounced ‘swinz’ by natives).

Background: SWNZ was started as a pilot project by a group of Hawke’s Bay winegrowers in 1995. Their original intentions were to look at and assess vineyard chemical usage. By 1997, the group had close to 120 vineyards self-assessing their operations, and by 2002 the programme included both vineyard and winery standards.

7 Pillars: SWNZ has developed seven so-called pillars of sustainability: soil, water, air, energy, by-products, people and business.
