Following his passing in 2011, Queen Noloyiso ascended to the throne as the acting Queen until her son, Prince Jonguxolo Sandile, came of age.
Eastern Cape chairperson of the house of Traditional Leaders, Chief Mwelo Nonkonyana, said the Queen Regent will be remembered for upholding the traditions, customs and culture of AmaRharhabe and Xhosa people.
Nonkonyana said: "We are saddened. It is a devastating blow to us because she has been in that queenship position for some time and really acquainted herself very well, acting on behalf of her son with diligence.
"As a princess from Kwa Zulu, she understood the institution of traditional leaders very well and upheld the tradition, culture and customs of AmaRharhabe nation and the entire Amaxhosa people.
"We convey our condolences to the entire Zulu and AmaXhosa nation as a whole and we hope we will work with them for the passing on ceremony of the Zulu princess and AmaRharhabe queen regent."
