She said the group has commissioned some research and this would be the subject of a council workshop next month.
"Government has suggested that community housing is not the domain of local government and we agreed that there may be other providers who can provide wider range of care services to residents than a council."
The council oversees 275 pensioner flats in 16 complexes and 11 relocatable granny flats.
A level of welfare assistance is provided to some tenants, with the council contracting Age Concern Whanganu as that provider.
The flats are available to people 55 years and over with limited financial resources who can live independently. But despite offering low rentals, occupancy has averaged around 89 per cent in the past four years.
Council said it would have to borrow $100,000 to $160,000 a year over the next decade or maintenance would have to be reduced.
"The majority of the submitters on this issue to our 10-Year Plan didn't agree with the proposal to sell all or some of portfolio," Ms Main said.
After considering those submissions council committed to ensuring its involvement in pensioner housing did not require ratepayer funding.
"We'll engage with the working group to review the best use of the portfolio and/or proceeds of any sale or partial sale. We're committed to ensuring our tenants are well cared for and there are favourable quality and affordable housing options available," she said.
