But public perception of clash between commercial interests and regulatory role highlighted.
The Financial Markets Authority has issued a favourable report card on the NZX and the way it handles its statutory obligations, but has singled out potential conflicts of interest between its commercial operations and its regulatory role as an area that could be improved.
The Securities Act requires the FMA to carry out a review, at least annually, of the exchange, and the authority said the NZX was compliant with obligations to ensure that each of its registered markets and the derivatives market were fair, orderly and transparent.
In its latest report, issued yesterday, the FMA said the NZX had spent considerable time on its conflict arrangements during the review period over 2013 and had implemented a number of changes.
"FMA is satisfied that NZX's conflict management framework is adequate for the identification and management of any potential conflicts that exist between the NZX's commercial interests and its role as frontline regulator and we have seen no evidence to suggest that the framework is not working as intended," the report said. "However, FMA has seen evidence of growing public perception that NZX's regulatory decision-making could be influenced by NZX's commercial interests, or other affiliations of NZX, and could undermine NZX's effectiveness as the market regulator and erode market confidence in the regulatory framework."
