He has also been serving as the Provincial Chairperson of the African National Congress (ANC) since his election on 12 May 2017.

[1] Zamani Saul completed his Grade 12 at Umso High School in Colesberg.

[5][6] On 12 May 2017, Saul was elected unopposed as the Provincial Chairperson of the African National Congress in the Northern Cape after Premier Sylvia Lucas had withdrawn her nomination for the position.

[12][13][14] In his first few months, he pledged to cut what he called "wastage" from the Northern Cape government; he declared that it was unacceptable and wasteful spending that as Premier he would be offered a bowl of fresh fruit every morning in his office and that his official car of Premier would be replaced after 120,000 km while ambulances in the province would run 952,000+km before replacement.

[15] Accordingly he banned Northern Cape ministers from getting new cars and used the money to buy 63 new ambulances instead.
