"This is the first time we've made a single vineyard gewürztraminer, so to take home a silver first up is incredible," says Mr Nooyen.
Only four other wineries were awarded a silver in the category.
The winery also took home bronze for its 2013 Sparkling Charminer and 2015 Vintage Port.
"All of our wines are hand-harvested and hand-crafted in small parcels to ensure we create high-quality wines. Both the port and sparkling charminer are top sellers for us, so to be recognised by industry experts with a bronze is the icing on the cake."
The family-owned winery is located north of Ohaupo at Rukuhia. It was established in 1922 by Ivan Milicich Snr and is now in its fifth generation of winemaking in New Zealand.
