The restrictions meant farmers were putting up QR codes, hand sanitisers and masks and then staying out of the sheds.
Some farmers preferred to do their own woolclassing, which was not possible under Alert Level 4 restrictions, so some were choosing to postpone for a couple of weeks, Herlihy said.
It also meant shearing teams were taking their own food and missing out the usual farm home-baking, as some farmers "go out of their way to spoil us".
Alert Level 3 made a difference, but there were restrictions, he said.
"The rules come out through the contractors association, but it's just something we have to adapt to.
"It's the new normal. We've been here before and to be fair, it's probably never going to be the way it was a couple of years ago."
But after last year's lockdown experience, Herlihy said most shearing contractors would have been better prepared this time around.
