Braden Crosby's innovative frost windmill blade system helped the Wairarapa viticulturalist take out this year's Young Horticulturist of the Year.
His frost windmill blade system can also be used for electricity generation. The judges noted that the project was delivered with real professionalism.
Winning the award saw Mr Crosby take out $11,500 worth of prizes including a $7,500 travel package.
The Carterton man also received further recognition when his windmill system claimed second place in the Agmardt Innovation Award.
"I got a lot more out of it than the prizes," Mr Crosby said. "I think the business development took me out of my comfort zone. I had to source and develop information and network with other people."
