Several top Inkatha Freedom Party officials were implicated during the hearings last week and on Monday another was named as being involved in hit squad activities.
According to a witness, Chief Khayelihle Mathaba, now a member of the provincial legislature, twice gave orders for men to be killed.
The witness was convicted killer and self-confessed hitsquad member Brian Mkhize, 31. Mkhize said one of the men Mathaba ordered killed was a headman in his area who was allegedly anti-IFP and was seen as troublesome.
Another convicted murderer and self-confessed hitsquad member, Romeo Mbambo, who has applied for amnesty, gave evidence for the first time on Monday.
His evidence corresponded with that of Mkhize and implicated many of the same people, including IFP MPP Lindiwe Mbuyazi, IFP secretary general MZ Khumalo and Richards Bay mayor BB Biyela.
Mbambo said he joined the IFP in the 1980s and the KwaZulu police in 1990.
He said he was approached by Mkhize to join the hitsquad and was taken to Mbuyazi, who explained everything to him.
He was then taken to a meeting in Ulundi where he met Major Leonard Langeni, Khumalo, and Caprivi trainee commander Daluxolo Luthuli, who gave details of work to be carried out by the hit squad.
Mbambo also said he deliberately destroyed evidence in cases that implicated IFP members.
He said he would write misleading evidence in the police dockets or destroy evidence at the scene of the crime. He was later arrested for the murder of a policeman and eventually sentenced to 75 years' imprisonment for seven murders.
Also testifying on Monday, Superintedent Christopher Marion said he was part of a special unit set up in 1986 to investigate the KwaZulu police and hitsquad activity.
He said among those identified as suspects by his unit were Prince Gideon Zulu, Major Leonard Langeni, MZ Khumalo, BB Biyela, Lindiwe Mbuyazi and Chief Mathaba.
He said the cases involving these and others were taken to the Attorney General in 1986, but he decided not to prosecute. "He said the matter would not succeed in a court of law."
Marion said violence was rife in the KwaZulu-Natal midlands during 1987.
"At one time I was attending up to 50 murder scenes," he said.
The hearings will continue on Thursday, when various legal representatives make submissions on behalf of their clients.
