Producer Statement and Memoranda Authors Register

What is a Producer Statement?

Producer Statements (PS) are formal written statements certifying that specific building work, design or specifications comply with technical requirements, in order to comply with the provisions of the New Zealand Building Code or a Building Consent.  The statement is signed by the author (a recognised specialist such as an engineer or architect) working within their scope of expertise and competency. It is the responsibility of the producer statement author to ensure that they meet the requirements of their industry code of practice, and that they provide a producer statement that is both complete and accurate. Acceptance of a Producer Statement  is discretionary. Producer Statements that are inadequate can be rejected by the Building Consent Authority (Council).  

Different types of Producer Statements (see also Templates). Guidance on use of producer statements on the IPENZ website also refer to the latest IPENZ Practice Note: Guidelines on Producer Statements (2014).

See also the MBIE Guidance document on Certificates of Work, Producer Statements & Design Features Reports (under RBW)

Statement Type


PS1 Producer Statement Design

Used by designers to certify specific design elements comply with the specific standards or codes in order to comply with the provisions of the Building Code. See Structural Engineering Design Office Practise (2009)

PS2 Producer Statement Design Review

Used by professionals undertaking a peer review of all or part of a design to say that the design or specified part of the design complies with specified standards or codes in order to comply with the provisions of the Building Code. See Practise Note 02 Peer Review.

PS3 Producer Statement Construction

Used by contractors or tradespeople to certify that the specified building work that they have undertaken complies with the Building Consent.  This is given to the supervising engineer, who then provides the Council with a PS4.

PS4 Producer Statement Construction Review

Used by engineers conducting a peer review of specified building work (undertaken by contractors or tradespeople) to certify that the building work complies with the Building Consent. See Guidelines: Construction Monitoring Services

What is a Memorandum?

A Memorandum is similar to a producer statement but is signed and written by tradespeople for specialist work to confirm that the work that they have undertaken meets the performance requirements of the NZ Building Code or a Building Consent. 

When are these statements used?

A Building Consent Authority (Council) can use Producer Statements or Memoranda to recognise building professionals and some trades whose design and construction work is, or will be, technically acceptable and will satisfy the provisions of the Building Consent. The Council may rely on a Producer Statement or Memorandum as "reasonable grounds" for assuring compliance. It is important that your Council can be confident of the reliability of these statements and that the statements' authors have appropriate experience and competence in their field(s).  
Your Council is part of the Waikato Building Consent Group, which has a register of approved authors of Producer Statements or Memoranda. It is important that you check that your engineer and tradespeople (if appropriate) are on the register.  If they are not registered, and they are not on any of the Registers of Designers and Tradespeople required by legislation, Council may not necessarily accept their Producer Statements or Memoranda, and as a consequence not sign off on your Code Compliance Certificate (CCC) at the end of your building project.  Acceptance of Producer Statements or Memoranda is discretionary.

Owners Responsibility

It is important to note that an engineer or other specialist inspection does not relieve the owner of their responsibility to ensure that all the required inspections set out on the Building Consent are completed by the Council. It is also the owner's responsibility to check that the person they employ is working within their scope of  expertise and competency. 

Information Required on a Producer Statement or Memorandum

If information is missing or inadequate the Producer Statement or Memorandum will not be accepted by Council. Templates for Producer Statements and Memoranda can be found on the website See also the Checklist used by Councils in the Waikato Building Consent Group to assess whether the document provides adequate information for compliance.
