Kaitiakitanga: It\u2019s a word the M\u0101ori, the indigenous people of New Zealand, use to describe their guardianship of the land, its people and its culture. It\u2019s also the key value shared by a wave of M\u0101ori wineries that\u2019s recently begun to swell across the country.\r\n\r\n\u201cIt\u2019s sustainability on steroids,\u201d says Lina Stroud, business manager of Tiki Wine & Vineyards, a M\u0101ori-owned winery in Christchurch. \u201cWe see ourselves as caretakers of the land and try to keep our footprint small to make sure that everyone gets to experience the magic of New Zealand.\u201d\r\n\r\nWith fewer than a dozen M\u0101ori wineries established, numbers are still small. But last year\u2019s formation of Tuku, a M\u0101ori winemakers collective, combined with increased interest from across the country has proven these producers are poised for their moment on the world stage. Here\u2019s a look at three of the most prominent.\r\n\r\n\r\nTohu Wines\r\nThough several New Zealand wine brands bear a M\u0101ori name, this was the first truly M\u0101ori-owned winery. Today, it has the farthest reach, and thousands of descendants from tribes that inhabited what\u2019s now recognized as the Marlborough wine region serve as its shareholders. Bottles, like entry-\u00adlevel Kono Sauvignon Blanc and premium offerings in its Kaum\u0101tua Range, are available across the U.S.\r\nSteve Bird Wines\r\nSteve Bird Wines is rooted in man\u0101kitanga, \u201ca generosity of spirit toward the land and each other.\u201d The producer traces its M\u0101ori roots back more than 800 years and sources from vineyards in Hawkes Bay, Gisborne and Marlborough. Two of its ranges are available stateside, the signature Steve Bird bottlings and Manu, which includes Sauvignon Blanc, Pinot Noir, Pinot Gris, a ros\u00e9 and a blend of Cabernet Sauvignon and Merlot.\r\nTiki Wine & Vineyards \r\nEvan Ward is the winemaker at sustainably focused Tiki Wine, where the principles of kaitiakitanga are applied in the vineyard to ensure that quality comes first. \u201cYou can make up a good story to promote a poor wine, but in the end, people will see through [it],\u201d says Ward. Two Tiki ranges are available in the states: the flagship Tiki Estate and Maui, named for a M\u0101ori demigod.
