Luckily he was able to rely on his rural roots and moved to his family's farm in Cave, South Canterbury, to work as a farm hand with sheep and Hereford cattle.
"I could get into farming quite easily because I have a bit of a background in it," he said.
"A lot of the guys in Queenstown ask me if I know anyone who needs a farm hand because they've got no work at the moment," said Mckerchar.
Mckerchar believed there were jobs available in the primary sector for those who found themselves unemployed due to Covid-19 restrictions. He encouraged people to consider working in farming.
"There's gonna be a lot of jobs going and anyone can come and get into it. My advice would be don't rule it out, farmers are good at sharing information and helping people learn."
One aspect of farming that Mckerchar revelled in, was how rewarding the lifestyle was.
"It's a cliché but, I love farming because you've got that fresh air, you're outdoors, it's quiet and every day is different. It keeps you on your toes, keeps you thinking."
"It feels good knowing you've done a good hard day's work, it's awesome."
In fact, Mckerchar enjoyed his career change so much, he said he wanted to continue working on farms - even when international tourism returned to full strength in New Zealand.
"I may keep my hand in flying, and do it part-time when conditions allow, but I just love it out here on the farm."
