In his five-year report card on the FMA, Everett gave the regulator a "pass".
The watchdog was pleased with its clean up of the finance company collapses, the transparency of its policy work, its engagement with newly-regulated sectors and the relationships it had built with its fellow regulators, he said.
However, there had been some challenges, including what Everett described as a switch in "enforcement focus from post-mortems on dead bodies to treating live ones".
There was a balancing act, he said, between speed and thoroughness and between openness and secrecy.
"There is an element of culture shock for firms that have not been regulated before and indeed those that are regulated elsewhere but can't grasp why the same needs to happen here in New Zealand...we still see defensive and adversarial positions taken in scenarios where a grown-up - and early - conversation would be infinitely preferable," he said.
Part of the FMA's focus was on "deepening and broadening" its perimeter, he said.
"What's inside our remit, what's outside and are those the right settings? You might think I am talking here about - FX trading, overseas entities, FSPR, scams etc. - and for sure there has been plenty of that," he said.
"But our anxiety about where our perimeter lies actually reflects that the biggest pieces of financial services in New Zealand sit outside it - by which I mean the banks and insurers. We don't license them, but their sales practices are covered by the fair dealing provisions of the FMC [Financial Market Conduct] Act. There is an issue of how far our conduct remit under the FMC Act can be stretched to cover what goes on at banks and insurers and how that can harm customers."
