Labour leader David Shearer's chief of staff has quit effective today.
He will be replaced by former chief press secretary Fran Mold.
A spokesman for Shearer said Alastair Cameron had left on good terms.
Mold has been contracting as a part time adviser to Shearer since she quit as chief press secretary earlier this year.
When Mold quit she said she was moving to Auckland where her partner had taken a job.
But since then Shearer's poll ratings have stagnated or gone backwards and there have been rumblings of discontent about how Shearer's office operates with repeated rumours - all denied until today - of impending reshuffles to get a stronger political focus in his office.
