Institutional shareholders need to place more focus on demanding quality corporate governance from firms they have investments in, says Financial Markets Authority chief executive Rob Everett.
In its strategic risk outlook report, released last week, the regulator said governance would be one of its seven strategic priorities over the next two to three years.
The FMA flagged concerns about director influence in New Zealand being "relatively concentrated in a small group of interconnected directors" who sit on many company boards.
"While some degree of interconnectedness is vital to the efficient functioning of our financial system, it can also serve to amplify existing market frictions, conflicts of interest, information asymmetries and other structural and behavioural factors," the report said.
Everett said there was much room for improvement in corporate governance in New Zealand.
