The nearest refuse transfer station was in Kaikohe, 13 kilometres from the forested section of Ngapipito Road.
"East West Waste also provides weekly kerbside rubbish and recycling collections in most communities near Ngapipito Road, including Kaikohe, Moerewa, Kawakawa, Ngawha, Ohaeawai, Pakaraka, Tautoro and Oromahoe," Mr Edmondson said.
The length of the road and its isolated nature made it impractical for the council to monitor it, but the council did issue infringement notices (fines) if it found evidence that enabled it to identify rubbish dumpers.
"A council contractor had removed a large pile of rubbish near the road on May 3," he added.
"We haven't received an invoice for this work yet, but it is likely to be in the region of $1500.
"We will investigate the latest dumping of rubbish and get quotes to remove this.
"Clearly this is costly for the council and ratepayers, so we would encourage people with information about illegal rubbish dumpers to contact us confidentially.
"We are also investigating other ways of managing this problem."
