On the back of an extremely wet winter that left many farmers unable to grow pasture or crops for spring, the early and unusual dry start to summer turned West Coast pastures "from swamp to concrete," he said.
"It was agreed that while farmers needed to plan for the worst, there was hope that the forecast rainstorms could break the drought before central government assistance became necessary. However, the Grey and Buller districts now meet the criteria for a medium-scale event," he said.
The classification gives the local Rural Support Trust and other recovery organisations a funding boost of up to $50,000 to help serve their communities, including organising local events and arranging recovery facilitators who work one-to-one with farmers.
The classification lasts for six months unless things change substantially beforehand.
Other usual recovery measures, which may include tax flexibility and income assistance options, will be made available where appropriate, he said.
