Notley says she will add women's issues to her responsibility as justice critic.
She is also taking over David Eggen's duties as health critic and giving him what was her responsibility for human services.
Notley is also giving up environment to former leader Brian Mason, who retains the critic role in energy and finance.
Deron Bilous continues as education critic and takes on housing.
Notley won the leadership of the party in a first-ballot victory on Oct. 18 over Eggen and union activist Rod Loyola.
"We are committing to Albertans that we will bring forward the issues that matter, not be bound by the government's agenda," Notley said Wednesday in a news release.
