Rob Everett, the chief executive of the Financial Markets Authority has resigned and will leave at the end of the year.
Mark Todd, FMA chairman, said Everett had done an outstanding job as the organisation's second chief executive, overseeing the implementation of the Financial Markets Conduct Act as well as helping to lead a national discussion around the need for conduct regulation in financial services.
"Rob has been, and will continue to be, a truly outstanding leader of the FMA, who will leave a lasting legacy. He has the greatest respect both within the FMA and among our many stakeholders," he said.
Everett is set to depart at the end of September but will take a flexible approach to smooth the transition to a new CEO.
Todd said while it was disappointed that Everett would be leaving, he recognised that after seven years in the role, Everett was ready for a well-deserved break and a change.
