Far North and Whangarei councils as well as the Government have repeatedly said there is no money for sealing roads outside the "national significance" criteria.
PTRAG and Whangarei council personnel have held meetings and will carry out a "drive-over" of the worst-affected roads at 10am today.
The road audit will take into account all potential road users and will produce a list of key hazards, safety issues and possible solutions.
In the meantime, the action group is awaiting answers to its questions over how, in breach of the Resource Management Act, the NRC gave consent for WDC roading contractors Fulton Hogan to use an oil-based dust suppressant outside homes and businesses.
"The most important detail for us concerning the Northland Regional Council is the fact that it consented to having a prohibited and illegal substance used on our unsealed roads. This product, tested by Hill Laboratories as being petroleum-based oil, was the council's answer for dust mitigation," Graham and Alex Wright said.
"If this dust mitigation strategy gets into our food chain will the Northland Regional Council be compensating those dairy farmers when Fonterra stops collecting their milk?"
