And breeders up and down the country are talking about her seemingly innate gift for picking the finest cows.
''It's a fluke,'' she said.
The 29-year-old is the daughter of established Timaru Holstein Friesian breeders Lindsay and Alison Trounce.
''Growing up with parents who are so keen, you pick it up.
''You also learn a lot of little things off other breeders,'' Miss Trounce said.
At present she is working for Rakaia dairy farmers Hayden and Jessie Dorman as assistant manager milking 800 cows.
This year, she was awarded the New Zealand Holstein Friesian Association (NZHFA) 2013 Lenslea Trophy which is given to the person who has been a member of the association for fewer than 10 years and has displayed the greatest effort and enthusiasm in showing during the show season.
Miss Trounce said she began showing stock when she was 7 years old, in the time-honoured way, showing pet calves.
Each season she covers the show circuit showing her parents', friends' and latterly her own cows, with growing success.
Despite the acknowledgment of her dedication and commitment to showing she said she had been most thrilled by her win with 2-year-old Tahora Million Tori VG86, in the Semex-Holstein Friesian New Zealand On-Farm Competition.
Prominent Australian judge Murray Sowter travelled around New Zealand to view Holstein Friesians selected as the best from their region before making final decisions which were announced at the NZHFA's conference, in Southland in June.
Miss Trounce said she was delighted with the win because it was the third successive year she had won in the on-farm challenge and this year it was a different cow which had won an award.
Tahora Million Tori VG86 went on from the on-farm success to take an award in the 2013 Holstein Friesian New Zealand-DeLaval All NZ Photo Competition announced last month.
As a busy 2IC Miss Trounce said she did not have much time to fit other interests in around working and showing and all that went with it - transporting, feeding, housing and grooming the stock so they will look their best in the ring.
There were some cows to she would ''keep an eye on'' to see how they measured up when it came to show time.
But she said her approach was to take each showing season ''as it comes''.
Regular events included the NZ Dairy Event, the Canterbury A and P Show and the Holstein-Friesian South Island championship show which will be held early next year in Rai Valley.
Miss Trounce said career-wise she planned to go sharemilking, with a view to buying her own farm and might establish her own stud in the future.
