The Government has announced a $10 million cash contribution for the reinstatement of the Christ Church Cathedral.
The Crown cash contribution of $10m is offered along with a $15m interest free loan.
The loan will be suspended if certain conditions are met.
The Christchurch City Council is also pledging a $10m cash contribution but that is subject to public consultation.
Bishop Victoria Matthews was absent today as National MP Nicky Wagner and Mayor Lianne Dalziel made the announcements.
In a statement Bishop Matthews says "this is a very generous offer .. but as the proposal has only just been received there will be much for the Synod members to ponder".
A decision on the earthquake-damaged building is expected to be made later this year.
The total cost of restoration is expected to top $100m.
