But Mrs Raffills said more illegal dumping was done in areas where collections were part of the rates rather than direct user-pays.
The council was told rates-funded areas in South Auckland had three times more cases of illegal dumping than the city's west and north.
Infrastructure and Services manager John Dragicevich said concerns about illegal dumping "going through the roof" were not realised when the booking system was introduced for Waitakere City.
This was because of increased effort on educating the community and enforcement. Cameras were trained on dumping hot spots and the message went out that "if you illegally dump we will find you".
Dumping did not stop because of the nature of the terrain in the west, with many curves in the road to Piha aiding people to toss the rubbish out the car window.
Illegal dumping was like the fight against graffiti.
"As soon as you remove it, it comes back," said Mr Dragicevich. "It increases again as soon as enforcement and education steps back."
He said enforcement had slipped, but could be corrected by harmonising computer and office systems and "spending more time in the courts".
Extra enforcement and stiff fines are proposed in the plan with communications and community engagement programmes.
The council could also appoint warranted litter officers and litter wardens and advocate for compulsory deposits on containers.
