While it was only the second time they had entered, they have been finalists several times in the Glammies.
When a set of early twins was born in July — both the sire and dam were Charollais-cross — Mr Morris reckoned they could be perfect for the competition.
The competition is open to all breeds and celebrates the quality and variety of lamb available in New Zealand with a focus on increasing the consumption of lamb.
Lambs are first judged for yield before being tested for tenderness at Lincoln University and then taste-tested at the show.
The overall winner is decided on points accumulated in the yield, tenderness test and final taste-testing stages. There are three different classes and the best four are selected from each class for the final taste test.
At 14.1kg, their entry was among the smallest in the line-up but its yield of 62.59% was "very, very good", Mrs Morris said.
The couple attended the show and watched the final judging. It was very exciting to win, she said.
The couple farmed at Edendale and then Waikoikoi, before moving into Gore, and later buying some nearby land, Mrs Morris said.
They have a Texel stud, which they established shortly after the breed was introduced to New Zealand in 1990.
● Young Kurow stock agent Madison Taylor won the Heartland Bank Young Auctioneers Competition.
Winning had been a goal for Mr Taylor, who works for Peter Walsh and Associates, after he finished runner-up last year.
He won a $2000 prize to attend the Sydney Royal Easter Show next year to attend the Australian version of the competition.
