Newsroom is reporting that the former Health Minister will not continue as an MP after the 2023 election.
The Labour MP has held the safe Dunedin (formerly Dunedin North) seat since 2011.
Dr Clark quit as Health Minister in July 2020 as penance for two breaches of Covid-19 pandemic lockdown regulations, Prime Minister Jacinda Ardern having earlier said she would have sacked him but for the health emergency.
The former Treasury analyst and one-time Associate Finance Minister, was given new roles as Minister of Commerce and Consumer Affairs and State Owned Enterprises.
In an RNZ interview published online this evening, Ms Arden said she would announce a "handful of retirements" next week - a list of ministers who won't contest the 2023 election - leaving the way clear for an executive refresh.
She confirmed to media that she would reshuffle the Cabinet early in the New Year.
At Parliament today, Dr Clark was asked by reporters if he was committed to standing at the next election, but would not confirm this.
"I don't have any comment to say on that at all. Any announcements will come in due course."
