All documents held by the Canterbury Earthquake Recovery Authority (CERA) regarding Christchurch's Cathedral will be released the public on Friday.
The Government is calling on the Anglican Church to also release all advice and documentation it has been working from because of public interest in the cathedral's partial deconstruction.
Demolition of the city landmark began a month ago after the Anglican Church decided the building in Cathedral Square was too badly damaged by the 2011 February earthquake to repair.
There has been opposition to the move, with some calling for the remainder of the building to be preserved and for it to be rebuilt it in its previous form.
Earthquake Recovery Minister Gerry Brownlee says he believes that, if the public is able to see the advice the Anglican Church has been working from, there is likely to be more understanding about the extent of the damage to the Cathedral and the rationale to partially deconstruct it.
Mr Brownlee said a demolition permit has been issued to deal with the unstable tower and further permits will be issued to partially deconstruct the building to no lower than two metres.
The Christchurch Civic Trust says the publication of about 1000 pages of documents regarding ChristChurch Cathedral is a positive step, but won't change its view that demolition should be reconsidered.
Civic trust chair Neil Roberts says the publication is well overdue and will help people understand details surrounding the decision.
However, Mr Roberts believes there are more conservative engineering options that need to be explored and the content of the documents will not affect that view.
The Anglican Church says it wants to speak directly with Gerry Brownlee before making a decision about releasing its documents.
