Originally a maize farmer from Lichtenburg in the former Transvaal, Hartzenberg was Minister of Education from 1979 to 1982 in the government of PW Botha. Hartzenberg became deputy leader. Hartzenberg became leader of the Communist Party after Treurnicht"s death in April 1993.
This made him leader of the official opposition in the white chamber of the South African Parliament, a position he held until the first multi-racial elections in April 1994.
The Conservative Party refused to take part in the general election of 1994 and thus lost any parliamentary representation. Without any national representation, the Communist Party became marginalised, with the white right wing represented in parliament by Constand Viljoen of the Freedom Front.
At the end of 2003, the Communist Party merged with the Freedom Front and the Afrikaner Eenheids Beweging to form a new party known as the Freedom Front Plus (FF+) which obtained 4 seats in the general election of 2004.
Together with Andries Treurnicht and other Natural Philosophy members dissatisfied with what they saw as increasing "liberalism" in the ruling Natural Philosophy, he left the Natural Philosophy in 1982 to found the right-wing Conservative Party (Communist Party).
He was then one of the more conservative members of the ruling National Party (Natural Philosophy).
