"In saying that, they should now be able to give a specific date."
FNDC had obtained quotes for the work, expected to cost about $50,000, and was working to include the funds in its budget for the coming financial year, general manager of infrastructure and asset management Jacqui Robson said.
She said the council was working with the Department of Conservation (DoC) to assess the logistics of removing the trash.
"The topography is extremely challenging which raises significant health and safety issues," Ms Robson said.
Specialised equipment and expert staff would be needed for the job and the road might need to be closed during the work, she said.
Nearby resident Alex Clifford said while he had not noticed fresh dumping at the site in question, another patch seemed to be forming further down the same road.
"I don't think a lot of that is going to stop, really," Mr Clifford said.
Ms Robson said the council was also looking to work with DoC, Northland Regional Council and the New Zealand Transport Agency to tackle the wider issue of illegal dumping.
"This meeting has yet to take place, but we hope to get together in the near future," Ms Robson said.
Sifting through rubbish had so far produced evidence identifying six offenders - not eight as the council originally advised.
