Abusing the skips, which have also been set up in Tomahawk and Waikouaiti, was not fair on those affected by last week's floods, Dunedin City Council recovery manager Rob West said.
"It’s disappointing that we are receiving some reports from contractors that some skips are being used for general waste.
"That is not what they’re there for and it’s not fair on those who genuinely need them.
"We again remind everyone these skips are for residents living in these areas to use and are only for items contaminated by floodwaters."
It was also important that sandbags should be returned to distribution centres and not put in the community skips, he said.
Council staff and contractors were continuing to work at eight slips sites around the city, and several popular tracks remained closed, the council said in a statement.
Two properties initially issued red stickers have since been reassessed and issued yellow stickers instead, while a third went from white to yellow.
Mr West said work to fix slips affecting public roads and infrastructure would take time, but was progressing well.
"We will be applying for emergency funding from the NZ Transport Agency Waka Kotahi for those slips that have affected the roading network, as is normal following an event of this type, but we don’t yet have an estimate of the cost of damage to the council’s infrastructure."
Tracks which remained closed included the Tomahawk Reserve Beach access track and Tunnel Beach track, due to washouts, and the Kaikorai Common, between Shetland and School Sts, because of potential contamination.
Water restrictions affecting West Harbour and Outram had been lifted and city's beaches could be visited, apart from Tomahawk.
Some road closures remained around Dunedin, but more than three-quarters of roads closed at the height of the weather event had reopened, Mr West said.
