In deciding what services to cut, the council's management worked with councillors on which services to reduce, "with the final decision made by councillors".
"There will be no significant impact on the community from any of these reductions," Mr Fermor said.
"The majority of this deferred maintenance was the result of managers reviewing the condition of assets and deciding that the scheduled maintenance could be deferred without reducing the effectiveness ... "
He said it was too early to determine what impact, if any, deferred maintenance from this year would have on future rates.
"Any deferred maintenance will impact on future costs, provided that maintenance is carried out.
"As with any other costs or service levels, deferred maintenance from [this year] will need to be considered as we start work on the 2018-28 Long Term Plan.
"All projects, levels of service and costs will be reassessed and prioritised as part of the Long Term Plan."
Whanganui mayor Hamish McDouall was happy with the balance achieved.
"It's not so much a loss as more a very considered look at what can be deferred," he said.
"There's no point in redoing carpet, for example, when it doesn't need to be done.
"Really when we get advised that there's no significant impact on the community [from cuts], how can you resist that? I think that's the key."
* The council has begun work on the 2018-28 long term plan where levels of service, affordability, debt levels and long-term sustainability will be considered.
