The increase is significantly higher than the 3.7 per cent increase signalled in the council's long-term plan, and is an average $287 increase per property.
On top of this, the council is also proposing to increase the price of user fees and charges in the areas where it has had to spend more.
Goudie said the council would be seeking public feedback on the proposal as part of its Annual Plan consultation from March 10 to April 14 and she urged the public to give feedback.
"We are concerned at the impact this rates increase may have on some ratepayers and we're committed to looking at options to reduce overall expenditure as we develop our next long-term plan over the next 12 months," Goudie said.
The exact impact of a rates increase on any property varies depending on the property type and location, and ratepayers will be given a clearer idea of how each option could impact their property's rates when the consultation document is released next month.
The council is also seeking feedback on what services the community values and what could be scrapped or reduced as it attempts to find savings.
