Staffing issues may be playing a part in a growing backlog of building inspections in Christchurch.
There is a seven-week delay to get routine on-site building inspections from the Christchurch City Council.
An average home needs 11 to 15 inspections throughout a build.
Its head of building consenting Robert Wright said demand is exceeding capacity.
Since August, four inspectors have left the team. A team leader has also left, as well as three people from "other areas" of the business.
