New Zealand has a successful wine industry, with about 76 million litres being exported in the year to June 2007. The first vines are thought to have been introduced by missionary Samuel Marsden, and planted in 1817 by Charles Gordon, superintendent of agriculture for the missionaries, according to Dr Richard Smart who was viticultural editor of both editions of The Oxford Companion to Wine. Official British resident James Busby is credited with producing wine at Kerikeri in 1833, and Charles Darwin noted the winery in his diary when he visited Kerikeri in 1835.
