Farmers in Canterbury have been making preparations in case of heavy snow.
Two workshops were in North Canterbury were held on Saturday for Civil Defence, Oxford's search and rescue team and Dairy New Zealand.
Over 50 people went through the process of how they would work together in an emergency.
Snow in August 1992 killed 2.9 million lambs alone.
North Canterbury Rural Support Trust chair Doug Archbold said heavy snow creates logistical problems too, such as access to farms and organising teams of snow-rakers, who have experience with livestock.
