"[Mum] has spent time on farms and realised that's what I enjoy. It's been great having something I enjoy doing every day."
The Young Farmer of the Year competition runs over 10 months and sees farmers from 22 districts advance through the district and then regional contests.
The best go through to the national final, a two-day event including a day of practical challenges, as well as technical elements such as an interview, speech and HR challenge.
NZ Young Farmers chief executive Terry Copeland said Mr New was among the many unacknowledged high achievers in farming.
He said the award showed there were opportunities in farming even for people without the family background.
Mr New takes away $80,000 in prizes including $15,000 cash, a $20,000 Honda ATV and a Massey University travel scholarship.
