Unwanted umbrellas, boogie boards and televisions could be the cause of clogged up rubbish bins in Christchurch.
The Christchurch City Council is urging people not to dump household rubbish in public bins as contractors work to keep up with the demand of piled up rubbish.
The council's acting head of parks Brent Smith says the problem is being exacerbated by people misusing the bins.
"Public rubbish bins are not the places to dump unwanted umbrellas, televisions boogie boards or your household rubbish," he says.
Over the busy summer months, the council increases the frequency at which bins around the city's beaches are emptied.
Last week the council was made aware of these problems with some bins overflowing in the Sumner area.
It has since added an extra bin collection round in the evening and the council's Urban Park Rangers are doing a sweep of the area in the mornings to pick up extra rubbish.
"Our contractor has collected 20 percent more rubbish this year compared with the same period last year," Mr Smith says.
"While the warm weather is partly to blame for the increase, people misusing the bins has been another contributing factor."
