Landcorp estimates that the heavy South Island snow falls will cost it more than $70,000.
Chief executive Chris Kelly said most of that is to cover the extra cost of workers and equipment, including helicopters, needed to reach stock on its farms in the Lake Mahinerangi area, west of Dunedin, in particular its Waipori Station.
Snow falls of up to two metres deep also damaged guttering on farm buildings that will have to be replaced.
Mr Kelly said heavy snow also stranded stock at the Molesworth Station in southern Marlborough.
If the snow had happened in a month or six weeks, it would have been more serious as it would have coincided with lambing and calving.
Mr Kelly said flooding also brought down cattle yards at its Waitangirua station north of Wellington.
