Murder accused Johan Williams, dubbed the Boland Killer, appeared at the Wellington Magistrates’ Court on Tuesday.
He now faces three charges of murder, one of assault and one of rape.
The women’s bodies were found after Williams pointed them out.
DNA tests have revealed that skeletal remains dug up on the R45 just outside Wellington belonged to Natalie Jonkers, 35.
The mother of three vanished six years ago and according to her family, had gone to meet with Williams for work.
In July, 21-year-old Kuils River mom, Chantell Matthysen, went missing after she too was to meet the suspect for a job.
Chantell had met Williams two years before when he had worked at the Wellington Train Station as a security guard.
She had taken the wrong train with her son and he offered them a place to stay for the night.
He then met her family and became a friend.
Williams had been on the run for more than a week after Chantell went missing and when he was eventually captured and questioned by police, he would only reveal the location of her body after he was allowed to see his child.
Chantell’s body was on Aubon Rue Farm.
The body of Maria Isaacs, 33, from Malmesbury, who had gone to Wellington on 16 June for work as well, was also found on the outskirts of Wellington.
Wellington police are now looking into cases of missing women as far back as 2012.
Case resumes on 1 October.
