Long-serving Labour MP Annette King has been confirmed as the party's new health spokeswoman in David Shearer's reshuffle of Opposition portfolios. She replaces Maryan Street who becomes environment spokeswoman.
In other major changes in the Labour line-up, deputy leader Grant Robertson has been given the lead role in making jobs one of Labour's big four themes in the run up to next year's election.
The other areas are health, education and housing, the latter job briefing handed to Auckland MP Phil Twyford.
Ms King and Mr Twyford are both moving to the front bench.
Senior whip Chris Hipkins will take over the shadow education portfolio from Nanaia Mahuta, who will instead take on responsibility for Maori development.
