Proposed changes to the Code of Ethics for sustainability assurance

Demand for sustainability information in external reports continues to grow - globally and here in New Zealand. 


Provision of ethical and independent assurance over this information is critical to support trust and confidence in sustainability reporting.

The International Ethics Standards Board of Accountants (IESBA) are proposing changes to their Code to address ethics and independence requirements for sustainability assurance practitioners. These key revisions are intended to be profession agnostic and able to be implemented by all sustainability assurance professionals.

Exposure Drafts

IESBA’s exposure draft and explanatory memorandum on Sustainability Ethics and Independence

We are keen to hear your views on the proposals to inform our submission to IESBA.
The key questions we are interested in hearing your views on are:

  • Are the proposed revisions at the right level for New Zealand?
  • Are the proposals sufficiently profession agnostic to be implemented by all sustainability assurance practitioners?

Our summary of the significant changes is included here.
