Tonga's Queen Mother Halaevalu Mata'aho has died in Auckland, aged 90.
Matangi Tonga reports the Queen Mother reportedly left Tonga for New Zealand last week.
Her granddaughter, Princess Angelika Latufuipeka Mata'aho, was reportedly by her side during her passing.
Tonga's King Tupou VI is understood to be away visiting the Niuas, a remote island group in the far north of Tonga.
The Queen Mother was the mother of two kings, George Tupou V and Tupou VI.
Born on 29 May 1926, she was the daughter of Heuifanga Veikune and Noble 'Ahome'e Manuopangai.
Queen Mata'aho married Siaosi Tāufa'āhau Tupoulahi, the eldest son of Queen Sālote Tupou III, in 1947.
Queen Mata'aho is survived by her son King Tupou VI and daughter Princess Sālote Mafile'o Pilolevu Tuita, 11 grandchildren and several great-grandchildren.
