Northland councils have dealt with hundreds of cases of illegally dumped rubbish in the past year.
They include one area where more than 800kg of rubbish was cleared - costing ratepayers tens of thousands of dollars in clean-up costs.
Whangarei District Council spent nearly $100,000 and 1000 hours cleaning up after "fly tippers" or illegal dumpers in the financial year to the end of May, according to council figures.
The local authority dealt with about 833 incidences of illegal dumping over the period.
Cleaning up cost $98,671 including tipping fees and took up 980 hours of council time, including time spent travelling to the sites of the rubbish.
