Argyle is one of two students from Palmerston North Boys' High School who have secured spots at Pukemiro Station.
James Waterson, 18, has also been accepted.
Argyle's family farm beef cattle and deer at Tokomaru.
He decided he wanted to undertake a cadetship several years ago and has been busy preparing for the opportunity.
"I've spent the past three years relief milking on a neighbouring dairy farm. I've also been doing work experience on a sheep and beef farm at Parapara, south of Raetihi," he said.
Applicants have to submit a curriculum vitae and do an interview as part of the application process.
"The interview was a lot less daunting than I expected it would be. The panel was really friendly. It was more of a conversation than an interview," he said.
"I did several practice interviews with teachers at school to help me prepare."
Argyle and Waterson both spend each Tuesday at a PrimaryITO Trades Academy, completing practical work and unit standards focused on sheep, beef and dairying.
"I think that training was quite beneficial to my application," said Argyle.
