Emotions have run high since the Anglican Church announced this month that the beloved cathedral, which was badly damaged in the Canterbury earthquakes, could not be saved and would be "deconstructed" to just a few metres.
The Wizard of Christchurch has launched a campaign to save the cathedral.
The Wizard, Ian Brackenbury Channell, 79, has performed in Christchurch's Cathedral Square for decades and was distraught by the Anglican Diocese of Christchurch's decision to demolish the building.
He, and others, have called on Bishop Victoria Matthews to release engineering reports she says show the cathedral receiving major damage in the December 23 quake.
The cathedral has been extensively damaged in earthquakes over the past 18 months, with its spire snapping in half during the fatal 6.3-magnitude quake of February 22 last year.
Ongoing shakes have caused further damage to the building, according to the Anglican Church.
Ms Matthews has said it would cost more than $100 million to repair the historic building, while experts have said the reconstruction could be done for as little as $20 million.
