Chefs from four local restaurants will be involved in the lamb on the plate section. Martinborough's Peppers Parehua, Medici Cafe, The Gamekeeper and Greytown's Wakelin House will choose three cuts of lamb and create three dishes that will be judged by a panel of three.
People will be able to taste the judged dishes but may have to pay a small charge, he said.
"This is a fantastic opportunity to showcase how different cuts of lamb can be cooked to perfection ... and a chance for the public to sample these and see if they can taste any varietal differences," he said.
Other lamb dishes will also be available for purchase on the day.
Ten farmers had entered so far, with entries closing today.
