TA assessments and reviews

Last updated: 26 July 2022

View assessments and reviews of councils in their role as territorial authorities (TAs).

The Ministry of Business, Innovation and Employment (MBIE) carries out assessments of TAs as part of its ongoing monitoring of councils performance. It looks at whether they have the appropriate systems, processes and resources in place to carry out their core TA functions under the Building Act 2004 (the Act). 

Reviews are reserved for instances where there is evidence that a TA may not be properly performing its functions and duties, or failing to properly exercise its powers under the Act, i.e. a suspected systemic failure of the TA in the performance or exercise of those functions or powers. These more formal reviews are carried out under section 276 of the Act. 

Assessments and reviews are carried out by a specialist team within MBIE. Team members involved in these assessments have extensive backgrounds in regulatory building control and building compliance. 

In 2020 MBIE implemented changes to its TA assessment programme to better align with its BCA and TA Compliance Strategy.

The changes aimed to ensure the process was more efficient and would allow more TAs, and TA functions, to be assessed more regularly. 

The 2022 Summary Report below outlines the new approach to assessments undertaken from 2020 onwards and the findings from these assessments. It also summarises the key findings from assessments prior to 2020 (previously called technical reviews). 

You can view reports of technical reviews for individual councils from February 2009 to October 2014. Individual reports from 2015 onwards will not be made publicly available. However, two-yearly summary reports provide an overview of the findings from that assessment period.
