Around 400 state homes in Auckland are on the city council's list for a potential buyout or flood mitigation, Kāinga Ora says.
Deputy chief executive for the region Caroline Butterworth said the council has advised it 380 addresses could be at future risk.
Auckland Council has notified landlords and homeowners that may fall into Category 2 or 3, but said not all will.
Category 2 homes need flood protection and Category 3 homes are for voluntary buyouts.
"Auckland Council has provided us with an initial list of Kāinga Ora properties that it believes could be exposed to some degree of risk in future severe weather events," Butterworth said.
"We are currently reconciling that list against our own records of properties that were damaged by the floods."
She said no risk categories had been assigned to any Kāinga Ora properties.
"We are working closely with Auckland Council and will be providing them with the information they need to help complete their risk assessment process, which will determine if any of our properties are classed as Category 3 under the government's risk categorisation framework."
Butterworth said some of the 380 addresses included multi-unit dwellings.
"We are continuing to work with Auckland Council to build a more accurate picture of the number of Kāinga Ora homes that could potentially be included in the different risk categories."
Auckland Council has sent out letters to 880 storm-affected homeowners of potentially high risk properties but has not decided which are in line for a buyout. Kāinga Ora received one letter with a list of properties.
The council is seeking more information from residents, including asking them what they think should happen with their homes.
