Mayor Steve Chadwick said she brought the issue up at a recent council committee meeting suggesting one option to help reduce illegal dumping was to open up the Rotorua landfill for limited free rubbish disposal, as she was aware dumping rubbish there was expensive for some people.
"Fly-tipping is a lazy thing to do, it's the lazy option and I wish we could find more evidence for prosecutions. I did suggest opening up the landfill for an open day, and you never know what we could flush out, and I'd like to see open days as another option as part of our comprehensive new waste strategy."
Rotorua's Kiri Danielle, who starred in a Maori Television series which held those illegally dumping rubbish to account, said people didn't realise how much damage one small act could do.
She said a decision to throw rubbish over a bridge or into a lake could cost somebody a lot of money, or the rubbish could remain there for hundreds of years, if nothing was done about it.
"You know they talk about a footprint - this is more like a punch."
Ms Danielle said rubbish was poisoning the land and getting into the water, as well having a visual impact and ruining people's enjoyment of a place.
"We absolutely need a change of culture, not only in Rotorua but in the country, because this generation is used to seeing it like that," she said.
Councils could help by making it easier for people to dispose of rubbish, she said.
"We need people to clean up the mess that's been made and then we need that shift in culture to keep it clean."
Ms Danielle said her next task was to create a Facebook video about her cause.
"Social media is a very powerful tool if it's used wisely," she said.
Keep New Zealand Beautiful chief executive Heather Saunderson said littering and illegal dumping were a large problem in New Zealand. Such illegal dumping had long-lasting effects on the community, health, environment, tourism, business, crime levels and the economy.
Ms Saunderson said more than 190,000 tonnes of litter and rubbish were collected from the streets of New Zealand by about 86,000 volunteers last year alone.
That was enough to fill 120 rugby fields to half-a-metre high with rubbish.
