On this page, we break down everything you need to know about CodeMark and E3. We explain the benefits of all our flooring collections having a CodeMark, as well as our newly CodeMark certified Envello Cladding, and how this helps streamline your specification process. We also explain what is covered in the E3 section of the Building Code and how to specify wood flooring in wet areas.
If you need more guidance about gaining compliance, please reach out and one of our Specification Consultants can walk you through the steps to help streamline your specification.
We are excited to be the first and only timber flooring supplier in New Zealand to have CodeMark for all Wood Flooring Collections and now have the most comprehensive timber flooring system that is fully compliant with the new building code changes.
Specifying our CodeMark certified timber flooring ensures the Building Consent Process is quicker, RFI’s are reduced and the possibility of council delaying consent in the submission stage of your project is eliminated.
Our decision to undergo the process of obtaining CodeMark certification for all our timber flooring collections was in response to feedback from clients who were having difficulties getting council consent for timber flooring in kitchens and other wet areas. Now that our flooring is fully compliant with the building code changes, you can rest assured that by specifying our products, you’ll easily gain consent from council.
What is CodeMark?
CodeMark certifies that a building product or building method meets the requirements of the New Zealand Building Code. It is an indisputable form of product assurance and has a legal status equivalent to that of an Acceptable Solution or Verification Method. In a nutshell, all CodeMark-certified products are automatically compliant with the Building Code.
Benefits of CodeMark certification
Reliable quality
First and foremost, CodeMark certification is a consistent and objective measure of quality. This means the products are always reliable, high quality, and reputable, giving you peace of mind.Efficient building consent applications
When processing building consent applications, authorities must accept a CodeMark certificate as evidence of compliance with the New Zealand Building Code, provided the product is used under the scope and limitations defined on the certificate. In summary, your consent process will be much smoother. This also results in a significant reduction in the time and money spent on council RFIs (Requests for Information).

We’re excited to share that the Millboard Envello range of composite cladding has achieved CodeMark certification.
For architects, designers and builders, this means streamlined consents, reduced documentation requirements, and the confidence that comes from specifying a product with verified, accepted compliance credentials.
Faster Consent Processing
Reference Millboard's CodeMark certificate in your specification and councils must accept it as compliant within the defined scope. No need to compile alternative solutions or respond to BCA questions about product suitability. The compliance pathway is established, documented and accepted.
Clearer Risk Management
The certificate defines exactly where and how Millboard can be used – including suitable substrates, cavity requirements, fixing specifications, and environmental conditions. This clarity helps you manage project risk and ensures installations stay within compliant parameters from specification through to completion.
Verified Performance Over Time
CodeMark certification isn't just about testing samples. The scheme assesses manufacturing processes, quality systems, and includes ongoing audits to ensure consistency. When you specify Millboard, you're selecting a product held to verifiable standards year after year.
Design Without Compromise
Millboard delivers the visual warmth and tactile quality of timber in a composite engineered to resist fading, warping, and decay. Now with CodeMark backing its performance claims, you can specify it with complete confidence in both aesthetics and compliance.
Specification Support

E3 is the section of the New Zealand Building Code that refers to Internal Moisture. It outlines the requirements for the following:
Adequate thermal resistance
Space temperature
Ventilation
Disposal of overflow water
Surfaces to be impervious and easily cleaned
A record of amendments is a record of changes to the acceptable solutions, verification methods, and handbooks.
E3/AS2 states that all surfaces in wet areas, such as bathrooms and laundries, must be impervious, easily cleaned, and have adequate ventilation. Having adequate solutions in place for humid environments is critical for occupant’s health, as well as the longevity of your flooring.
