18: Building work not required to achieve performance criteria additional to or more restrictive than building code
or “The law says you only need to follow the building code rules, not any extra or stricter rules, when doing building work.”

You could also call this:

“The building authority must accept different ways to show that a building follows the rules.”

You need to know how to show that a building follows the building code. A building consent authority must accept several ways to prove this. They include:

Following the rules mentioned in section 20 of this law.

Using an acceptable solution or a verification method.

Getting a decision from the chief executive that says it follows the code.

Having a current national multiple-use approval, as long as you meet all the conditions.

Having a current registered product certificate, if you follow all the conditions.

For modular components designed and made by a registered MCM, having a current manufacturer’s certificate from that MCM.

Having a certificate that shows the energy work follows the rules in the Electricity Act 1992 or Gas Act 1992, which also means it follows the building code.

When thinking about whether something follows the building code, a building consent authority or regional authority must look at any warnings or bans that are in place. They can also look at any guidance information from the chief executive.

                1. to the extent that compliance with a requirement imposed by regulations made under the Electricity Act 1992 or the Gas Act 1992 is compliance with any particular provisions of the building code, a certificate issued under any of those regulations to the effect that any energy work complies with those requirements.
                  1. In considering whether something complies with the building code, a building consent authority or, as the case may be, a regional authority—

                  2. must have regard to any relevant warning or ban in force under section 26(2); and
