IPENZ who represent engineers in NZ have created a new Code of Ethical Conduct which came into force on 1 July 2016. This Code sets out professional engineers’ duty to the public and to each other.
Level provides the guide to codes, BRANZ bulletins and standards also for sustainable best practices including ventilation, controlling noise, natural light etc.
MBIE has funded a number of standards for free download. This includes NZS 3604:2011 Timber Framed Buildings. You can download PDFs of these standards for personal use only.
