The Ministry for Primary Industries have published a brochure to help farmers prepare for what could be a drier summer.
MPI minister Nathan Guy says farmers are being urged to prepare for the possible impact of El Nino conditions.
"While every El Nino is different and the impacts on New Zealand can be hard to predict, it often means drier conditions in the north and east, with cooler temperatures and more rain in the west.
"This would not be good for those on the east coast of the South Island who have had a very dry 12 months already and are still officially in drought. That's why it is important to plan and start preparing now."
The brochure's advice includes planning, implementing a feed budget, irrigation, talking to experts, animal care and work/life balance.
"Farmers are resourceful and used to dealing with the challenges thrown up by Mother Nature. The key is to be ready and start preparing now."
The brochure has been prepared with the support of Beef + Lamb NZ, Dairy NZ, Rural Support Trusts, Federated Farmers, Rural Women New Zealand, the New Zealand Bankers Association and the New Zealand Veterinary Association. It is available at www.mpi.govt.nz
