"My grandparents are farmers. They used to operate a dairy farm and that's where I discovered my love for dairy cows," he said.
"I have been so fortunate that Wendy has been such an amazing mentor. I look forward to spending time on the farm."
Wendy Harker is on the board of Holstein Friesian NZ and heavily involved in advancing genetics in the dairy sector.
It has provided Seebeck and Seager with plenty of opportunities to help prepare and lead dairy cattle at A&P Shows.
They have gained skills in animal husbandry, showmanship and nutrition; they have even started acquiring their own dairy cattle.
"I bought my last calf club calf off Wendy and David. I paid for grazing when she was young," said Seebeck.
The cow, Westell Aftershock Seatle, calved for the first time last year. She had a heifer which he named Crozier Meridian Santiago.
A photo of Seebeck and Santiago clipped and show ring-ready was runner-up in the senior section of a national competition run by Holstein Friesian NZ.
Brad Seager and his heifer Westell Alcove Lacey placed first.
Wendy and David gave Seebeck another calf this year and he also owns a cow at Tim Barclay's dairy farm.
He purchased another calf in partnership with fellow teenage breeder and classmate Boyd Ferguson of Te Awamutu last year at the Next Generation Sale in Hamilton.
"That's four and a half dairy cattle in total. I'm keen to continue building my numbers," said Seebeck.
Seebeck attended the South Island Holstein Friesian Championships at the NZ Agricultural Show last November.
It was an opportunity to catch up with Dean Geddes, whose stud Tahora Holsteins milks 350 cows at Tai Tapu.
The Geddes' hosted the National All Dairy Breeds Youth Camp at their farm last year, which Seebeck attended.
"It was great spending a few days learning new skills around preparing animals for the show ring," he said.
"It was an enjoyable way to meet other like minded young people who are interested in the same things as I am."
Seebeck was also part of the team that placed second in the youth challenge at this year's International Dairy Week Australia in January.
