"This reduction is due to projects coming in below budget, or where work is being partially or fully deferred into the next financial year," he said.
Also contributing to the surplus are increased revenue from the Rotorua Museum and higher-than-expected revenue from resource consent fees.
The council's overall debt is $161.6 million, $5.9 million less than at the beginning of the year, with no more borrowing planned this financial year, meaning a reduction of $7 million from budget.
"In addition to no new borrowing the improved operating result and lower capital expense will mean council is forecast to hold a higher cash balance by $2.3 million at the start of the year," Mr Sands said in his report.
According to another report from council business performance and procurement analyst James Simpson, some of the council's key performance indicators have been missed, including removal of graffiti and the cleaning of toilets in the inner city, and six monthly inspections of all high and very high risk food and liquor premises.
Mr Sands said contractors responsible for graffiti removal and public toilet cleaning would be reminded of their contractual obligations.
