After the end of apartheid, she represented the ANC as a local councillor in Greater Pretoria until she was elected as Mayor;[3] she vacated the mayoral office when Greater Pretoria became the Tshwane Metropolitan Municipality in 2000.
Mashishi was sworn in to the National Assembly on 14 May 2004, shortly after the 2004 general election; she filled a seat that Joyce Kgoali had declined to fill.[4] In the next general election in 2009, she was elected to a full term in the assembly.[5] She did not stand for re-election in 2014.
