Christchurch City Council is investigating its options to provide rates relief for some quake-affected residents.
In April, councillors voted against full relief for owners of uninhabitable homes. However, it has now commissioned a report into other funding options.
The full cost is estimated at up to $7.3 million.
Cr Glen Livingston, who supports a100% rebate, says it could be funded by delaying repairs to buildings that are not urgent.
A report on the funding options will be presented to the council on Thursday.
