Mr Gardyne was a finalist in 2007, 2009, 2010, 2011 and 2012 before winning the grand champion title last year. It was the first time the competition had been won with a Perendale.
This year, he was runner-up in the best of breed (traditional) class, with a Perendale lamb and highly commended in best of breed (open) with a Perendale/Suffolk/Texel. Both lambs were processed at Alliance Group's Lorneville plant.
Mr Gardyne, who has farmed for 52 years, attributed his success to experience and practice.
``Consumers are now much more interested in the food they eat and where it comes from. Reflecting on the past decade, a lot of effort has been put into the management and genetic makeup of the animal to fine-tune the lamb we produce. Gaining an award like this is a huge thrill and gives me confidence in what is to come,'' he said.
Following an independent assessment for yield, tenderness, succulence and colour, the top 20 finalists this year were judged by Beef + Lamb New Zealand ambassador chefs at the Wanaka A&P Show.
Forbes and Angus Cameron, from Ashhurst, topped the 166 entries with a Growbulk lamb processed at Alliance Group's Dannevirke plant. The Camerons also won the beef equivalent competition, Steak of Origin, in 2015.
Beef + Lamb chief executive Sam McIvor said the competition recognised the quality aspects that were so important to the customer.
``The excellent results are a reflection of the work that farmers, processors and scientists have put into driving these aspects of lamb production,'' he said.
