Mark Stewart: Christ Church Cathedral Reinstatement Limited chair on the rebuild facing uncertainty amid multi-million cost blowout - Heather du Plessis-Allan Drive

The Christ Church Cathedral rebuild is at risk of being mothballed if an extra $30 million isn't found by August. 

The total cost of the project is estimated to be at almost a quarter of a billion dollars, according to the New Zealand Institute of Economic Research.

Christ Church Cathedral Reinstatement Limited chair Mark Stewart says they've turned to multiple sources to fill the financial gap.

"We're looking for support from central Government, from the Christchurch City Council, obviously the Anglican Church itself, in terms of hopefully getting some money."
