What is a CodeMark certification?
CodeMark is a voluntary scheme operated by the Ministry of Business, Innovation and Employment in New Zealand and the Australian Building Codes Board in Australia.
A CodeMark certificate demonstrates that a product, design or method meets specified Building Code clauses. The certificate sets out the product/method, the Building Code clauses covered and the scope, limitations and conditions for use.
Products that are certified are listed on public registers and are permitted to use the CodeMark brand in their marketing materials, but only for the scope for which certification has been granted.
BRANZ accredited for New Zealand and Australia
Both New Zealand and Australia operate their own separate CodeMark schemes, meaning certificates are valid only within the country where they are issued.
BRANZ is accredited by JASANZ to certify products for both the New Zealand and Australian Building Codes and markets.
What CodeMark certification covers
A CodeMark certificate sets out the product/method, the Building Code clauses covered and the scope, limitations and conditions for use.
This gives you marketing advantage through public register listing and use of the CodeMark brand.
Why choose CodeMark certification?
Providing confidence and certainty
A CodeMark certificate must be accepted by building consent authorities in New Zealand and unrestricted building certifiers in Australia as fulfilling the requirements of the respective building codes, provided it is applied within the scope detailed by the certificate.
Useful for innovative products and solutions
CodeMark certification is particularly valuable for innovative products or systems entering the market or those where failure could have serious consequences.
Get the marketing advantage
CodeMark certification provides marketing advantage through public register listing and use of the CodeMark brand.
Your options
In some cases, your product may be better suited to other assurance options such as a BRANZ Appraisal, a technical opinion or one-off or tailored testing. BRANZ can help you decide what best fits your goals and timeline.
The CodeMark certification process
Step 1: Confirm the scope and claims
Agree the intended scope of use and the Building Code clauses to be covered.
Step 2: Evaluate the evidence
Review test reports, assessments and technical documentation against the stated requirements.
Step 3: Check quality controls
Review the quality control plan and manufacturing controls to support consistent production.
Step 4: Audit and verify if required
This may include manufacturing, distribution and/or site audits to confirm systems and practices.
Step 5: Certification decision and certificate issue
Once sufficient evidence is available, the CodeMark certificate is prepared and issued.
Step 6: Ongoing confidence
Certification includes a plan for ongoing reviews and audits, so the basis of certification remains current.
Supporting documents to provide for CodeMark certification
- Name of product (or method) intended for certification.
- Technical specification of the product/method.
- Manufacturing details (including where it is made and how it is controlled).
- Product quality control plan.
- Intended scope of use (where and how it can be used).
- Responsibilities for supply, design and installation.
- Technical literature (e.g. technical datasheets and installation instructions).
- Specific clauses of the New Zealand or Australian Building Code you are claiming compliance with and seeking certification for.
Typical timeframes
- If all required supporting information is provided at the start, the process is often around 3–4 months.
- A 6–12-month timeframe is more typical when the product/system is still under development or innovative, supporting information is missing/unsatisfactory or additional testing is required.
