The judge read a letter from a farm manager for Rhodes had been working, regularly and unpaid, in connection with the course.
The letter described Rhodes as "reliable, sensible", and "a pleasure to have around", saying he was respected by staff and would become a capable farm worker.
"This is a great letter," Judge Hastings said.
"To my mind you have taken on board your father's advice not to go down the path he went down at your age.
"It does seem to me that you have turned a corner and I really hope that you have.
Judge Hastings sentenced Rhodes to six months community detention, 80 hours community work, and nine months supervision including a Tikanga Maori programme.
