Marlborough is New Zealand's most important wine region by far. Situated at the northeastern tip of the South Island, this dry, sunny region is home to more than 500 growers and produces more than three-quarters of all New Zealand wine. Vineyard area exceeded 26,000 hectares in 2018.

It is particularly famous for its pungent, zesty white wines made from the Sauvignon Blanc grape variety, which dominates the Marlborough vineyards. In 2017 the variety accounted for 79 percent of vineyard surface area and 86 percent of regional production.

Marlborough Sauvignon Blanc remains the bread-and-butter performer for the industry, and many wineries from outside the region own or lease vineyards, or buy grapes or wine to be able to offer this key product and strengthen their portfolio.
