Federated Farmers is urging South Island farmers who still need help to get to stock trapped in deep snow to contact the rural support trust network.
Teams of volunteers have been out helping farmers this week to get to stock or bring them food and water.
Adverse events spokesperson Katie Milne said there may still be farmers in the back country who need a helping hand and they need to make contact by calling 0800 787-254, which gets them through to their local Rural Support Trust.
Mid-Canterbury president Chris Allen said severe overnight frosts are holding up the snow thaw in many areas.
That's keeping stock from their normal winter feed crops, such as kale and turnips, and even more importantly snow and ice is blocking access to water.
Mr Allen said sheep and cattle won't eat snow and need running water.
He said the priority is to give stock access to water and that can mean breaking ice off the top of troughs or getting access to a creek.
