A Bay of Plenty-based winemaker has won further accolades at an international competition for the second year in a row.

Morton Estate's chardonnay has taken the trophy for Best International Chardonnay over £10 at the Decanter Wine Awards in London for its second vintage Coniglio.

The judges say that Coniglio?s dominance of the competition for two years shows the quality of New Zealand's chardonnay wines.

They say the country that is famed for its sauvignon blanc also needs to be taken seriously for its chardonnay.
