Thames Coromandel wants to hit ratepayers with a 10 per cent rates increase from July and hike up fees and charges.
And even then the council says the proposed 9.98 per cent increase is not enough to cover the its burgeoning operating costs which caused it to blow its budget by more than $12 million in two years.
It would also have to borrow money in the form of a short-term loan that would be paid back from future rates increases and a reprioritisation of council's spending. The rising costs have caused council to overspend by $6.7m in 2018/19 and it is forecast to blow out again by $6.7m in 2019/20.
Thames Coromandel mayor Sandra Goudie said the cost of maintaining council's current services had escalated at a much faster rate than that estimated two years ago.
Goudie blames increased costs around rubbish and recycling and core infrastructure costs, higher contractor rates in the civil construction industry due to increased competition and a council commitment to increase the delivery of the capital works programme.
