Although Catherine is new to this role, Rebecca has played Glinda, the Good Witch, previously in Invercargill and Christchurch.
Both young actresses are looking forward to working with the New Plymouth Operatic Society.
Wicked tells the story of the Land of Oz before Dorothy dropped in. Meeting at University, the young Elphaba and Glinda spark an unlikely friendship.
Through the trials and tribulations of friendship, love and rivalry, Wicked appeals to all ages.
Winning more than 90 awards internationally, Wicked has cast its spell over audiences world-wide and is an unforgettable, enchanting experience not to be missed, Carolyn says.
■ Wicked: June 18 to July 11 at the TSB Showplace in New Plymouth.
