A former Christchurch mayor believes the council should refuse to help fund the operation costs of the planned cardboard cathedral.
The temporary building, to be built on the corner of the Hereford and Madras streets where the demolished St John's Church once stood, is expected to cost about $5m.
Insurance money is expected to cover about $4m, and fundraising will cover the shortfall.
The Anglican Church received $240,000 a year for the running of the quake-damaged ChristChurch Cathedral up until July last year.
It's now seeking the same amount for the building's replacement, Fairfax Media reports.
