Christopher Luxon doesn't think the Reserve Bank's reputation has suffered any long-term damage.

Neil Quigley resigned as chair of the central bank on Friday night, after Nicola Willis raised concerns over its handling of Adrian Orr's resignation earlier this year.

Willis has revealed to Newstalk ZB, she would have asked Quigley to resign, if he hadn't resigned of his own accord.

The Prime Minister says Quigley has made the right decision.

He doesn't think the current situation is a mess, but it would have been a shambles if it had carried out much longer.
