Keep New Zealand Beautiful says its annual ''clean-up week'', which started on Monday, has attracted more volunteers than ever.
There are 560, self-run, events planned across the country with schools, associations and councils getting involved.
Sixty-three events are registered in Canterbury.
The cleanup week encourages the community to get out and tidy up their own ''backyard'.
Earlier this year, Mayor Lianne Dalziel said Christchurch needed to "look a lot better" than it did if it wanted to keep its Garden City image.
In 2016, the council received 1000 more complaints than it did in 2015 about rubbish, untidy properties, parks and other issues.
A council report said there had been a downward trend in public satisfaction over waterway quality, litter, roads and park quality since the quakes.
