Mayor Steve Chadwick said the rating should give the community confidence in the financial stability of the council and the sustainability of the proposed long-term plan.
"This adds to our confidence in continuing to invest in our growing district. It also aids our ability to attract investment into Rotorua because it provides assurance for potential investors and central government that we will prudently manage their investment.
"We have committed to ensuring we have a prudent and sustainable financial framework that provides longer term assurance for the organisation and for our community, a turn-around from what was a pretty bleak picture a few years ago.
"Council has worked very hard to rectify that as part of ensuring we have an efficient and effective organisation that is adaptable, resilient and able to deliver.
"Fitch is a totally independent agency which provides an additional lens on our finances to ensure we remain on track. They cast a very critical eye on all aspects of council so it's very pleasing to have retained such a good rating given the challenges we've faced with building closures affecting revenue and adverse weather inflicting additional costs on the council.
"This also affirms the financial prudence of our draft long-term plan which Fitch scrutinised as part of their assessment."
Collé announced the Fitch rating during this week's Operations and Monitoring Committee meeting.
