A total of 263 submissions were received and a hearing took two days. Last month councillors asked for more modelling, including looking at differentials for forestry and high-value homes.
Mayor Craig Little said the review was a "massive task".
"If we had not taken the review as far as we did, we would not have collected such a vast amount of feedback.
"We have struck a balance where we have listened to the community while achieving a future rating system that is simple, affordable and appropriate," he said.
The forestry differential reflected community feedback that the sector contributes less towards the social, economic and environmental wellbeing of the district, he said.
