McCulloch's parents were "pretty excited" their son had been selected as a finalist.
"They said: 'You might find yourself a bloody bird'."
McCulloch's ideal date would be taking a woman out for a pig hunt.
"If she doesn't want to come she could sit and read a book for a while, but I'd talk her round it... We'd go for a soak in the hot pools, then have a feed at the pub."
McCulloch's dogs Patch and Snatch would have to give a bachelorette their lick of approval.
It's "people from all walks of life" who turn up to his classes, McKenzie said.
The 29-year-old spent Summer 2015 hitchhiking around New Zealand.
"You see parts of New Zealand most people don't see... The best place was East Coast in the North-- you're picked up not as a hitchhiker but as a person."
McKenzie, who calls himself a jack of all trades, said he's keen to put his best foot forward this week.
• Jason Clotworthy, NORTHLAND
Jason Clotworthy is no stranger to competition, he made the regional finals of New Zealand's Young Farmer of the Year in 2015.
Depending on whether he's mustering or not, "brekkie's at 5.30am".
He's handy with a quad bike, and feels his independence could give him an edge.
"A lot of work which I do out here I mostly work on a quad bike. You sort of have to be able to do everything up here because you're usually so isolated you can't really call anyone for help."
As for his bachelor status, he attributes it to his remote location.
"There's absolutely no girls where I am. Anywhere where you're out bush there's no girls at all. If there are girls they're very quick to get snapped up by other blokes."
Fieldays Rural Bachelor winner 2016 Paul Olsen, 35, was snapped up within weeks following his win.
The Opiki potato farmer, who also works with drystock and in dairy farming, said he has "a great girlfriend now".
"I met her shortly after the competition just through mutual friends... She's in the rural, agricultural industry, so we've got common interests and common goals," he said.
"We're not living together at the moment, but we'll just see how things go."
Olsen added his Golden Gumboot wasn't on full display at home-- it's tucked away in his office.
"I'm not that brave to have it out... A few of my mates would probably give me s*** for it."
