The campaign will take six drinkers to Cambodia to discover the local culture, accompanied by winning National Geographic Assignment photographer, Michael Yamashita.
The winners will then head to New Zealand to meet chief winemaker Patrick Materman at the Brancott vineyard in the Marlborough region.
Consumers need to visit the brand’s Facebook page, upload a picture capturing the nature of the UK.
Lucy Bearman, head of marketing for Brancott Estate, said: “The partnership between Brancott Estate and National Geographic Assignment is a natural fit, with both companies celebrating curiosity. We have a history of curiosity, given that we were the first to plant and pioneer the world’s first Marlborough Sauvignon Blanc wine – a style that has since changed the course of New Zealand’s wine industry.
“In the same pioneering vein, National Geographic Assignment represents only the top geographic photographers, whose inquisitive nature has led them into careers where their curiosity is encouraged.”
