The reburial of King Goodwill Zwelithini's mother will cost the taxpayer R300 million.
Durban municipality spokesman Thembinkosi Ngcobo said the cost was justified as the project would benefit the community and promote the Zulu nation, the SABC reported on Wednesday.
The remains of Queen Thomozile Jezangani KaNdwandwe Zulu had been exhumed and would be reburied in Cato Manor on Saturday.
An unveiling and memorial ceremony would be held at the Umkhumbane Freedom Park on Sunday.
