"I just love being outside, getting my hands dirty and working with dogs. I love the general work too like fencing and shearing."
His aim is to own his own farm.
Mr Powell impressed the judges with his first round written answers to open-ended questions and then with his second round performance, showing the judges his farm and explaining his duties.
"My main goal is to make a good name for myself and to buy my own farm one day. Every dollar I make will go towards that," Mr Powell said.
Taratahi's Sheep and Beef Farm Manager Paul Crick named Mr Powell as the winner.
"I'm thrilled that Taratahi is the sponsor of Shepherd of the Year. There are some really talented shepherds out there and they deserve to be acknowledged and enjoy some time in the spotlight," Mr Crick said.
Sir Brian Lochore was at the event and was encouraged by the young farming talent.
"I applaud this competition, anything that recognises excellence in the industry is good.
"To be a great shepherd you have to have the all-round ability to turn your hand to anything. You are the future managers and owners and the industry needs you desperately. The opportunities you will have in the future will only get bigger and bigger," Sir Brian said. The prize pool for the competition was $7000. Mr Powell won $4500 in prizes and cash and the two runners-up, Cameron Dallas and Jakeb Herron each won a Lister shearing hand piece.
