Federated Farmers is warning next year's production in Hawke's Bay might be affected if the dry spell continues.
No significant rain is forecast for the region in the next few weeks.
The President of Hawke's Bay Federated Farmers, Will Foley, said the tail end of Cyclone Pam provided some relief last month.
But he said the rain was not evenly spread, with the southern part of the region between Takapau and Patangata still very dry.
"Generally Autumn's a time to build up seed and get stock for the winter, and that's just not really happening," he said.
Mr Foley said farmers were coping well, but if the dry spell continued they might not have enough feed to carry stock through winter.
