Those whose homes increased in value more than the overall increase of 12.8% would pay more general rates, while those with a lower increase would pay less.
The new valuations came out late last year.
The Dunedin City Council's valuation service provider, Quotable Value, revalues Dunedin's 55,185 rateable properties for rating purposes every three years.
At the meeting yesterday, council chief executive Sue Bidrose explained what the revaluation would mean to homeowners, once the budget was completed and rates for 2017-18 were set at the end of July.
Ms Bidrose said the changes could be "complex, and difficult to understand".
When property prices rose people generally thought that meant rates would rise, but that was not necessarily the case.
Instead, the increases or decreases depended on an individual property's value rise compared to the overall rise.
Cr Mike Lord, a Berwick farmer and former Federated Farmers Otago president, raised the problems farmers faced with increasing rates and decreasing incomes.
"Most farm incomes have dropped dramatically in the last few years," he told the meeting.
"Is it time to look at the differentials?" he asked.
Ms Bidrose said they could be considered in the next long-term plan meeting in January next year.
Mayor Dave Cull said a regular review of which sort of property paid how much in rates was "appropriate".
Mr Hunt said the organisation had been following the issue.
"Certainly we would expect the council would adjust the differential to reflect the difference."
He said farmers' incomes were under "incredible pressure" and that was not just dairy farmers.
"Rates are in some cases quite a large percentage of a farm's budget.
"Most farmers understand rates have to be paid. However, it is important that they are fair and equitable."
The report to the meeting showed the median house price in Dunedin was $285,000.
There were 46,546 residential properties in the city paying general rates.
Of those, 80% were worth between $150,001 and $470,000.
There were 142 properties with a capital value of $1.5million or more.
Included among the properties were 76 blocks of flats, community houses and cribs, 27 rest homes, halls of residence and boarding houses, five large areas of vacant land and 34 private residences.
