Auckland's historic St James Theatre could cost $60 million to $70 million to restore.
Steve Bielby, principal trustee for the building's developer, the Auckland Notable Properties Trust, said those were the estimates for a full restoration. Funding was yet to be secured but he was optimistic it could be sourced.
"The owner has some obligation," Mr Bielby said, referring to Relianz Holdings, which bought the St James last year. "But there's going to need to be public funding for this.
"We're close to closing the gap between the owner's funding and the public. We've been talking to Auckland Council, the Government, trusts - everyone. There will need to be a contribution from a large number of parties."
Noel Reardon, Auckland Council's heritage manager, indicated the Super City's financial contribution was unspecified.
