Gomba joined the ANC and started her political career as a municipal councillor of the Buffalo City Metropolitan Municipality.[2] During her tenure on the council, she was one of the longest-serving councillors. She and many other councillors were charged in relation to the scandal around Nelson Mandela's funeral.[3]
On 12 February 2021, Gomba appeared at the East London Magistrate's Court on charges of corruption, money laundering, fraud, and violation of the Municipal Finance Act in relation to the alleged siphoning of a portion of the R10 million that was meant for Mandela's funeral, through flouting tender processes. She is one of 14 co-accused.[8] On 18 February, premier Mabuyane dismissed her as the MEC for Health. She will remain as an ordinary member of the Eastern Cape provincial legislature.[9]
While in a Zoom meeting with minister Mkhize and her provincial counterparts on 28 April 2020, Gomba said: "andidikwe" (meaning "I am fed up"). Her comment generated controversy, and she subsequently apologised, saying that she was misunderstood.[13][14]
On 12 June 2020, the Eastern Cape Health Department launched a project, in which they bought scooters to address the challenge of people being rushed to hospitals in wheelbarrows in rural areas in the province. The project was seen as controversial and a failure.[15]
On 13 December 2020, Gomba tested positive for the coronavirus,[16] but she since recovered.
