Several dairy sheds near Culverden have been damaged by this morning's quake, leaving farmers unable to milk their cows.
Sam Smith, who lives on a dairy farm at Culverden, said he'd been lucky to have little damage at his house or farm, but knew of several others with significant damage.
"A lot of platforms that cows stand on have been smashed so [farmers] can't milk their cows which is a massive problem. Their sheds are just about condemned."
Smith has a friend on a farm at Waiau whose house and dairy sheds were wrecked.
"They're absolutely totaled. There's liquefaction everywhere as well which is kind of crazy."
