The Manawatu-Whanganui regional council is offering help to farmers tackling clean-up and repair work on their farms from last week's flooding.
The council and Primary Industries Ministry are assessing crop losses in the lower Turakina and Whangaehu areas.
There is also widespread damage to farm roads, bridges and culverts extending into the upper Whanganui River catchment in the Central Plateau. Replacing those with improved or large structures may require consents.
Council regulatory manager Richard Munneke says its aim is to leave farmers as free as possible to get on with the repairs, without bogging them down in paperwork and bureaucracy.
He says farmers need to have a look at what they have got and if it is a 'like for like' replacement they should just get on and do it.
Mr Munneke says the council wants to know, however farmers should not have to apply for consent at this stage and should just to get on with things.
He says the council can also help with some engineering advice to help farmers make a better replacement, if for example the culverts were too small for the event they experienced and need to be resized.
Farmers can talk to land management officers in the first instance about whether or not they may need a consent.
