Syrah, Pinot Gris and Gewurztraminer saw the biggest percentage rises in production off relatively small bases, and the crop of signature variety Sauvignon Blanc rose 26% to 229,000 tonnes, accounting for two-thirds of total output.
Total grape production in biggest region Marlborough was up by a third to 252,000 tonnes.
Chief executive Philip Gregan said: “An outstanding New Zealand summer provided near perfect conditions for growing grapes across the country.
“We expect the 2013 wines to be vibrant, fruit-driven and complex expressions of our diverse grape growing regions.
“The small 2012 grape crop left the industry unable to meet continuing strong consumer demand in established and new markets.
“Winemakers will welcome the more normal 2013 harvest as the better balanced supply will facilitate renewed export growth in the year ahead.”
