"The only issue I have is the sustainability of it. Our focus is on making sure that this doesn't fall over," Bilderbeck said.
Some of the money could also be used for a study of the hubs' impact and the steps needed to ensure their sustainability.
The library hubs align well with the council's leading edge strategy, Bilderbeck said. At Hakeke St adults have used the hub to embark on new study and start study groups.
Volunteers who are new immigrants use their time there to practice speaking English, and being there makes them feel part of the community. Some have set up a regular mahjong group, others teach Pasifika dancing.
The Whanganui District Health Board holds whanau information sessions at the hub.
Both hubs operate in "vulnerable communities", Bilderbeck said. They act as co-ordinators of welfare.
"We are asking you to believe in that and partner with us," she told councillors.
The hubs would like to extend their services, perhaps providing a place where people could pay their rates, or providing access to office equipment and study resources.
