The wave of extreme weather lashing the North Island is likely to have a devastating impact on the rural sector.

Crops, culverts, and feed have been destroyed by the floods and orchards and fields have been left underwater due to Friday's heavy rainfall.

The Country's Jamie Mackay says this will be a tough time for farmers and this will likely push up the price of food for consumers.

Jamie Mackay says these floods are coming off the back of two wetter than average months for the North Island, which have disrupted maize production.
