New Zealand's wine production is relatively small, currently the world's 15th largest wine-producing country, but growing steadily every year thanks to the popularity of their most prevalent wine style, Sauvignon Blanc from the Marlborough region. New Zealand is comprised of two primary islands, North Island and South Island. Warmer North Island's most popular red wine varieties are Cabernet Sauvignon, Merlot, and Pinot Noir. Chardonnay is the primary white wine. Hawke's Bay is the largest wine region on North Island.
