The 235 houses in Christchurch still without sewage systems since the earthquake on 4 September should have a temporary solution by mid-November.
Christchurch City Council is installing temporary sewage holding tanks that will be emptied daily, enabling residents to start using their toilets, showers and washing machines again.
So far temporary tanks have been installed at 37 properties.
About 2500 Christchurch properties still have only limited sewage systems.
The council says it could be up to two years before things are back to normal.
