The Anglican church in Christchurch has formally decided there will be a cathedral on the existing ChristChurch Cathedral site.
The decision to demolish the severely earthquake-damaged building has been halted by the High Court after an injunction was sought by a group of campaigners trying to save it.
As well as committing to providing a building, the church's owner, the Church Property Trustees, also says it will halt the demolition of what is left of the cathedral.
It has asked its engineers to review the information presented to the court in support of saving the existing building.
The trustees have asked the Canterbury Earthquake Recovery Authority for its opinion on the restoration proposal made to the court.
