Stock exchange operator NZX chief executive Mark Peterson has resigned from the role - and will step down at the end of April 2026.

Peterson explained that the time was right for him to stand down and for the board to look for a new chief executive.

He says he's overseen plenty of challenges and successes in the role over the last few years.

"You've got to make these tough calls - but we've also, at the same time, got to a period in the exchange where we've ticked off a bunch of expectations and objectives...really, it's the right time."
