Dog Point Vineyard has dedicated a large portion of their property to planting native trees, orchards and vegetable gardens as well as creating wetlands and open spaces alongside organic vines.

Dog Point Vineyard may have won the supreme award but Mother Nature was the big winner at Marlborough's top environmental awards, its organiser says.

The biennial Cawthron Marlborough Environment Awards wrapped up with the awards dinner last week where those making the biggest moves to improve the region's environment were celebrated.

Awards co-ordinator Bev Doole said this year saw the biggest turnout at the awards dinner as well as some very close competitions among the entrants.

"There were some really tight decisions this year for the judges," she said.

"It might sound a bit cliche but the environment was the winner on the night. There was a great range of entries this year too.

DEREK FLYNN/FAIRFAX NZ Muller Station owners Steve and Mary Satterthwaite won the farming category.

"The judges look for something from the winners that others can learn from."

Dog Point Vineyard took out the supreme award for its work planting native trees, orchards and vegetable gardens as well as creating wetlands and open spaces alongside organic vines.

"The strength of Dog Point is they are an established operation. They are a really good example that you can be commercial and environmentally friendly."

The company also won the landscape and habitat enhancement category.

Owner Marg Sutherland said she was surprised they even won their category let alone the supreme award.

"It was a thrill, actually, we felt really honoured to be rewarded for something we really love to do," she said.

Other winners on the night were Muller Station (farming), Southern Water Engineering (business innovation), Tohu Wines (wine industry innovation), Nelmac Garden Marlborough (community innovation) and Sanford in the new marine category.

Bev said she was particularly pleased to see such strong and diverse entrants in the new category.

The awards used to have an aquaculture category about 10 or 12 years ago, so it was good to have a category dedicated to the marine environment again, Bev said.

"I think we will definitely keep the marine category in coming years."
