The golds went to Main Divide's 2019 sauvignon blanc, 2015 riesling, and 2017 merlot cabernet.
Main Divide's 2017 merlot cabernet was also placed in the top 50 wines, selected from the gold medal winners.
They were produced by the team at Pegasus Bay under the direction of Matt Donaldson.
Tasting notes said the merlot blend provided ripe fruit and drinkability, while the cabernet sauvignon gave body, backbone and structure.
''The result is a rich wine with ripe flavours of red berries, plums and blueberry, the fruit is sweet and the flavour full with a long soft finish. Pair this with lamb shoulder chops slow cooked with thyme and onions.''
Judging chairman Jim Harre says to earn a gold medal, a wine will have been tasted up to 19 times by 11 different judges before being awarded this merit, and champion wines will have been tasted up to 36 times.
All entries are tasted blind, meaning judges see the wine only in the glass, never in a bottle.
Well over a thousand wines entered the 2019 New World Wine Awards. Entries were judged by 17 independent experts over three days to award gold, silver and bronze medals, as well as champion trophies and the top 50 rankings.
The Donaldson family has been involved in wine since the early 1970s and were pioneers of the North Canterbury region.
Their Pegasus Bay Winery and Vineyard is a true family affair.
Ivan Donaldson, who had a long career as an associate professor and consultant neurologist, as well as being a wine writer and wine judge, oversees viticulture and wine styles.
He began the vineyard while holding down his day job.
His wife, Christine, established the gardens at Pegasus Bay and maintains the extensive grounds.
Their eldest son, Ed, takes care of the marketing; Matt is the winemaker; his younger brother, Paul, is the general manager; his other brother, Mike, is their local sales manager; and Ed's wife, Belinda, runs the restaurant.
They have two brands in operation: Pegasus Bay, which includes only fruit grown on their estate; while their Main Divide brand focuses on fruit that is sourced from growers around the region.
About 10 years ago the family planted their own vineyards for Main Divide, so they now grow about half the fruit for Main Divide themselves.
The top 50 gold-medal-winning wines are available in all liquor-selling New World stores nationwide until November 10, selling at $25 and below. However, not all medal-winning wines are available at New World as they do not have to be stocked by the supermarket chain to enter the awards.
