Rotorua residents are being urged not to overload rubbish bags or include sharp objects after Castlecorp rubbish collectors were injured picking up bags.
Rotorua District Council solid-waste manager Tim Senington said people needed to consider the weight and contents of their rubbish bags and be conscious that workers had to lift them into the back of trucks.
"In the past, there have even been reports of people having to take their bags to the kerb in wheelbarrows because they're too heavy to carry. So it's irresponsible and unfair to expect council staff to have to pick up very heavy bags that put themselves at risk of injury."
Mr Senington said people also needed to be reminded of the ever-present risks to staff from collecting kerbside rubbish bags - such as cuts, infections, muscle strains, back sprains, biological waste, repetitive strain injuries and constant traffic.
"Residents should only put out safe household waste - not hot ashes, liquids, unwrapped sharp objects or other dangerous items. As well as cuts, there's always the risk of infection and other serious accidents.
