Keep Rotorua Beautiful chairman Craig Morley said neighbours noticed cars and trailers parking down the street and throwing waste on to the site.
"We've got sofas here too - it's like a dead-end street so people can come in and drop things off."
He invited the community to get in touch to let them know what areas needed to be cleaned up, and to volunteer to clean areas for the week.
"People have a lot of civic pride. Once they contribute to clearing up an area it often becomes ongoing."
He said people could adopt an area or get their business involved, either for the week or as part of ongoing projects.
Keep Rotorua Beautiful is funded by grants and sponsorship, with support from Rotorua Lakes Council.
