"He runs his farm profitably and sustainably, and has undertaken to share his knowledge and learning with others.
"From today he will work with the rural community to help other farmers understand the challenge of climate change and what options they have right now to reduce biological emissions on their farm."
Fraser McGougan is a fourth-generation farmer running the family farm of 420 cows near Whakatane. He and his wife aim to focus on what they can do well and keeping costs down.
The McGougans won the Best People Leadership in the Dairy Business of the Year awards, as well as Low Input with Best Financials and Best Bay of Plenty-Central Plateau Farm Performance in 2016.
"As younger farmers we are looking to the future," McGougan said.
"I want our farm to be seen as an example of what can be done on a pretty standard farm, while balancing profitability and environmental standards.
"Small steps now lead to big differences down the track. We've already reduced our use of fresh water, decreased nitrogen use and are retiring and replanting native bush. But I know we are just at the beginning of this journey.
"All farms are different, and one size doesn't fit all – but I look forward to working with other farmers who are heading in the same direction."
Mackle said emission reduction was a challenge facing the entire food sector worldwide, and New Zealand was well placed to take on opportunity to showcase sustainable dairy to the world.
"New Zealand is already one of the lowest emission producers of dairy in the world. But for New Zealand to achieve its 2030 target, we must look at ways to reduce all gases across all sectors.
"This isn't just about dairy – all sectors need to scrutinise the way they operate. Only together can we help New Zealand transition to a low carbon economy."
