Current Codes of New Zealand
New Zealand Building Code Clause H1 Energy Efficiency
This provision requires many buildings, such as housing, to achieve an adequate degree of energy efficiency to modify temperature, humidity, ventilation, the provision of hot water and artificial lighting. It does not apply to all buildings.
New Zealand already has a current building energy code as well as national programs in place to help support the code and assist residents and tenants with energy efficiency. The next step is to develop an update and change cycle to Clause H1 of the NZBC. This will systematically ensure that the code stays current and incorporates the most recent advancements in building science.

Clause H1 was first published in 1992; it has since been updated in 2004 and 2007. The code sets standards for thermal envelope, air flow, passive daylighting, water heating, lighting, and other building components. It also provides a verification method which includes a performance index. The code references many New Zealand standards, which are otherwise voluntary.
One of the first legislative acts in New Zealand building history was the Building Act of 1991. The act set out to improve the control of best practices in building design and construction, and to create the Building Industry Authority. The Building Act of 2004 dissolved the Building Industry Authority and replaced it with the Department of Building and Housing, which is currently responsible for publishing the New Zealand Building Code (NZBC).
