The teams were challenged to take a whole lamb and a side of beef to create a butchery display within two hours in the competition, which Britain entered for the first time this year.
Wedderburn’s captain Corey Winder said: "The pressure was definitely on. We’ve put a lot of work into this competition and it feels great to walk away with the result we were after.
"Being on our home turf created the perfect setting for an unforgettable experience."
Welcoming Britain to the competition, Kim Doran, organiser from Retail Meat New Zealand, said: "The British team’s presence encouraged a more intense test match with a healthy dose of rivalry.
"It’s a good-natured competition and it’s great to see a real sense of sportsmanship and camaraderie developing among the butchers."
