Dunderdale didn't drop anyone from her cabinet in making the shuffle on Friday in St. John's.
One of more significant changes sees Felix Collins move from justice to intergovernmental affairs, while Darin King becomes justice minister and is also government house leader.
Finance Minister Tom Marshall takes on the additional responsibility of attorney general, while Tom Hedderson becomes environment minister after serving as transportation minister.
Dunderdale also announced the establishment of the Office of Public Engagement.
She says the new office will make more extensive use of social media in the government's public consultations.
