Steve Morris, John Robson and Rick Curach were in support of the library, providing costs stayed within the $1.8 million collected from development contributions.
Mr Robson thought it was important for the council to find another $15,000 annually to pay for the library to be open on a Sunday, like the Papamoa and central city libraries.
Kelvin Clout said he was for it and the city had waited long enough. He said the city debt issue was major, but this was one project he wanted to see go through.
Matt Cowley said libraries were not just about books, but also other services they could provide to the community, such as upskilling people with the use of technology. He said he would support expansion provided it could fit in with the city vision.
Bev Edlin said the library was a community space and needed to be developed accordingly.
Mayor Stuart Crosby, Clayton Mitchell and Bill Grainger said they supported the library expansion. Catherine Stewart said she had an open mind but was against selling adjacent properties without consulting the city. She said she would need more information.
Gail McIntosh said was yet to study the full business case for the library and would need to be convinced doubling its size would not mean extra staff members. She was concerned about the ongoing operational costs of the library and the extra burden on taxpayers.
