An engineer has presented Christchurch City Council with a step-by-step plan to stabilise, then repair, the city's Anglican cathedral.
Demolition of ChristChurch Cathedral was put on hold after court action last year brought by the Great Christchurch Buildings Trust.
Engineer Adam Thornton of Dunning Thornton Consultants made the presentation to the council on Thursday on behalf of the Great Christchurch Buildings Trust.
The group, led by former MP Jim Anderton, formally requested the council to support it in its bid to restore the earthquake-damaged building.
Former city missioner David Morrell told councillors it was their duty to act as custodians for a recognisable part of what will be a wholly new central city.
The Anglican Diocese intends to carry out a consultation so people can have their say on options to restore or replace the cathedral.
A timetable for a public discussion has been laid out by the diocese and will start in two weeks.
