Berryman would have the power to make recommendations to the Labour Party, but won't be looking specifically into the four complaints.
The review was expected to take two to three months and every member of the party would be contacted in relation to it, Labour Party president Nigel Haworth said.
"A statement will be issued when the review has been completed, outlining any recommendations as well as the steps the Labour Party will be taking to implement them," he said.
"The Labour Party will fully cooperate with Ms Berryman's requirements in the completion of her review."
Berryman would begin the review straight away with the initial focus of her investigation on the Young Labour camp in February, Haworth said.
