"Farmers in these regions are used to drought and have been well prepared to deal with this summer's additional El Nino effect."
Mr Guy announced extra funding of up to $150,000 to local Rural Support Trusts to help combat the effects of the drought, with $40,000 of that going to the North Canterbury Trust.
Green Party agricultural spokeswoman Eugenie Sage said more action is needed on climate change to prevent more frequent droughts.
"Farmers are central to New Zealand's success as an export based economy and have much to lose from destabilising changes to the climate.
"A major challenge and opportunity for farmers and New Zealand is how to continue to produce meat, milk and fibre products whilst reducing climate pollution which comes from farming livestock."
