Wellington City Council media manager Richard MacLean said at this point the cars could not be saved.
Zorn said the news has a silver lining.
"In a sense it's a bit of a green light, there's an upside. Now I know that I can go buy another car."
He is not sure yet whether his insurance company will pay out until his other car is confirmed destroyed in the demolition, but even if he were to get it back unscathed, he didn't expect to get it back until about March.
MacLean could not say yet how long the demolition process was expected to take, but it was likely to be weeks, if not a couple of months.
There was a possibility demolition could begin before Christmas, but it was more likely to start early in the new year.
He didn't expect the cordons around Tory St would need to be extended for the demolition.
