Mrs McRostie and Lynley Caldwell are co-directing the show which will be held in the auditorium at St Kevins College on September 19, 24 and 26.
Featuring more than 45 performers, it incorporates dancing, drumming and music and will include "a few guest cameos".
"That's the surprise factor," Mrs McRostie said.
A talking drum from Papua New Guinea, donated to the community by Wayne Stringer, will also be making its debut. After the show, it will be housed in the Opera House and will be available for community use.
The show has backing from the Whitestone Community Arts Council plus support from the Creative Communities scheme.
Mrs McRostie is also organising the South Island's first drum and dance camp at Camp Iona on November 1 and 2, with master drummer Mohamed Bangoura from West Africa.
