Drought and flood-affected farmers in Canterbury need alternative grazing for their livestock, says the Ministry for Primary Industries.
Widespread flooding caused by a historic one in 200-year rainfall event caused significant damage to thousands of hectares across the region.
MPI had allocated $4.5 million to support flood-affected farmers, including providing grants to help repair uninsurable damage to farms.
"I have visited farms where pasture and winter fodder crops have been buried under flood debris," MPI's director of Rural Communities and Farming Support Nick Story said.
"This event has been an extremely challenging situation for farmers. The worst affected farms have a need for alternative grazing for their sheep, beef cattle and dairy cows."
