David Clark has resigned from his role as Health Minister.
He says the job has been a privilege and he's given it his all.
National leader Todd Muller told Newstalk ZB's Chris Lynch his party had been calling for Clark's resignation, and welcomed it.
"Ultimately he had a job to do on behalf of the Government and on behalf of the people of this country.
"It is our view that he did not deliver that to the standards that we expected, neither through the lockdown or the border management in recent weeks which has been utterly shambolic.
"As difficult as that announcement was for him, it is the right thing to do and should really have occurred several weeks ago."
