The Christchurch City Council will meet this week to consider how to keep rate increases to single figures over the course of the next three years.
The council has an estimated shortfall of $1.2 billion, and is facing rate increases of up to 10 percent.
One of its options for trying to keep rate increases down is selling shares in some of its commercial assets.
The financial strategy will be debated at a meeting on Thursday, and will go out for public feedback in March, with a final decision made in June.
Christchurch mayor Lianne Dalziel said the financial challenges were huge and that the council needed input from residents to help make smart choices about paying for the shortfall.
