Assessors from International Accreditation New Zealand are returning to the Christchurch City Council's consents department, as it continues its struggle to regain its accreditation authority.
In July last year, the council was stripped of its consenting authority, following its slow handling of post-earthquake building consent applications.
A report from IANZ in August found the council was still falling short of the standards required to regain the authority.
Council spokesperson Peter Sparrow said the next assessment, in November, would review the 18 areas that IANZ said still needed to be improved.
Mr Sparrow said the assessors will be on site for five days.
More than $8 million has been spent on the overhaul, including the installation of a Crown manager.
