Last week's "blizzard-like" cold snap has killed more than 200 cows on farms on the West Coast of the South Island.
The Kowhitirangi community is rallying around farmers who lost large numbers of stock in sub-zero temperatures last week.
Westland Milk Products chief executive Rod Quin said the weather system, which saw temperatures in the Hokitika Valley plummet to -10C last Wednesday, had killed 200 head of cattle.
"In spite of heroic efforts to try to move stock to shelter by farm staff, neighbours and veterinarians in attendance, 180 cows died, a serious loss for Barry Paterson, who is a supplier to and director of Westland Milk Products," Mr Quin said.
Twenty cows died on fellow director Raelyn Lourie's farm nearby, as well as a few animals on other farms in the Kokatahi-Kowhitirangi areas.
