Early yesterday, 500 "Lone Hill'' cows belonging to Lachlan Johnston began an almost-six-hour trek starting on Pannets Rd near Clydevale.
The herd then walked through Clydevale, over the one-lane Clydevale Bridge, through Greenfields and then on to Tuapeka Mouth.
Tairua said it was the third time she and a groupof keen women riders had helped move the Johnston family's herd.
"We are just a group of women riders who step up to help our neighbours move their dairy herds during the national dairy moving day.
"The presence of our horses seems to settle the cows. It makes them easier to manage and we have a lot of fun driving them slowly along the roads to their winter grazing paddocks," she said.
"I've had little sleep these past few days worrying about everything and planning on how to keep both the cows and my family safe on the roads as we walked the 20km to the winter grazing paddocks near Tuapeka Mouth," he said.
