New Zealand Winegrowers is the national industry body that represents New Zealand's viticulture and winemaking sectors. It conducts research, promotion, marketing and advocacy in the interests of New Zealand grape growers and winemakers, both domestically and in international export markets. Winemakers and grape growers are automatically entitled to membership of New Zealand Winegrowers through payment of the levies on grape or wine sales required by law in the Commodity Levies Act 1991 and the Wine Act 2003. This combined with New Zealand's small size means that it is the only country in the world with a single national wine industry body.[1]
