New Zealand wine is produced in several of its distinct winegrowing regions. As an island country in the South Pacific Ocean, New Zealand has a largely maritime climate, although its elongated geography produces considerable regional variation from north to south. Like many other New World wines, New Zealand wine is usually produced and labelled as single varietal wines, or if blended, winemakers list the varietal components on the label. New Zealand is best known for its Marlborough Sauvignon Blanc, and more recently its dense, concentrated Pinot Noir from Marlborough, Martinborough and Central Otago.

The Marlborough wine region is by far New Zealand's largest, accounting for three quarters of the country's wine production, 70% of its vineyard area and 85% of its wine exports. A Geographical Indication in the north-east of the South Island, it covers the entire Marlborough District and the Kaikōura District of the Canterbury Region, but in practice the vineyards are concentrated around the Blenheim and Seddon townships. Internationally, Marlborough Sauvignon Blanc is recognised as world class; wine writers such as Oz Clarke and George Taber have described it as the best in the world.
