Understanding Producer Statements
Producer statements play a vital role in New Zealand's construction process, yet many homeowners find them confusing. If you're building or renovating your home, understanding these documents can save you time, money, and stress.
What Are Producer Statements?
Producer statements are documents issued by design professionals and contractors that confirm specific building work complies with the New Zealand Building Code. They were introduced to streamline the building consent process and provide Building Consent Authorities (BCAs) with reasonable grounds for issuing building consents and code compliance certificates.
The Four Types of Producer Statements
There are four main types of producer statements, each serving a different purpose in the construction process:
PS1 - Design: Issued by a qualified designer confirming the proposed design complies with the Building Code.
PS2 - Design Review: Provided by a qualified professional who reviews someone else's design work. These are not typically required for standard residential construction.
PS3 - Construction: Issued by the builder or installer confirming the work has been completed according to the approved plans.
PS4 - Construction Review: Provided by a design professional who observed the construction to verify it meets the approved design.
Construction Monitoring and Producer Statements
Construction monitoring is often misunderstood by homeowners. It's not about supervising builders or managing the construction process - it's about verifying that critical elements are built according to the approved design.
Construction monitoring services typically fall into different levels (CM1-CM5), with higher levels involving more frequent site visits and detailed inspections. Your designer or engineer will recommend the appropriate level based on your project's complexity.
The PS4 (Construction Review) is the document that confirms this monitoring has taken place. Without proper construction monitoring and the resulting PS4, you may face difficulties obtaining your code of compliance certificate.
Why Producer Statements Matter to Homeowners
Producer statements protect you by ensuring:
Your home meets safety and durability requirements
Council has professional assurance that work complies with the Building Code
Future insurance claims aren't rejected due to non-compliant work
Potential issues are spotted before they become expensive problems
Your property value is protected through proper documentation
Common Pitfalls from an Engineer's Perspective
Not getting an engineer to site on time: This could mean unnecessary demolition to expose work for inspection. Schedule engineer visits at the appropriate construction stages.
Last minute inspection booking: The inspection is not the PS4 - it's just one component and needs to be successfully completed (all work must be correct, and there might be remedial requirements). An appropriately registered engineer also needs to review the work before signing it off.
Not having all the documents to complete a PS4: Generally speaking, consented plans, PS3 or Record of Works, and the PS1 are required, but other documentation like fiber dosage (concrete) certificates might also be needed. It's best to pre-check what documentation will be required.
Not knowing what inspections are required: It's difficult to know exactly which inspections are needed. The Council's Form 5 and the PS1 are the best starting points, but it can be complex. For example, piles usually require separate geotechnical and structural inspections, but if they fall within NZS3604's scope, they may not.
Common Questions from Homeowners
"Do I need to pay for construction monitoring?"
Yes. Construction monitoring of a specific engineer design (SED) is a professional service provided by your designer or engineer and should be budgeted for in your project costs.
"Can I skip producer statements to save money?"
This is a risky approach. Without proper producer statements, councils may refuse to issue code compliance certificates, which can affect your insurance, mortgage, and property value.
Getting the Process Right
When planning your build or renovation:
Discuss producer statements and construction monitoring with your designer early
Ensure monitoring costs are included in your budget
Keep copies of all producer statements for your records
Understand which statements your council requires before work begins
Pro tip: Have your builder or yourself, thoroughly document all phases of the construction process with photos. These might help you prove compliance if required.
By understanding producer statements and construction monitoring, you'll navigate your building project with greater confidence and fewer surprises.
