To gain an overview of what building methods and products must comply with in New Zealand, it is worth looking at the three levels of 'requirements' established by the Government:
The first level is the Building Act 2004 legislation - approved by Parliament.
The second level is the Building Regulations 1992 - which contain a section commonly referred to as the "Building Code", approved by the Government.
The third level of requirements are published New Zealand or overseas Standards or Test Methods or Calculation methods, cited in documents that have been published under authority of the Government, by the Department of Building & Housing commonly called "acceptable solutions".
The following pages (indexed in the left column) explain in more detail what each level means and how this information is referred to, as part of the appraisal process.
