The newspaper's duty of care to its employees has been called into question after Rosalyn Albaniel Evara died in hospital this month.
Photos displayed during her funeral showed clear signs that she'd been injured recently.
Ms Evara's former boss, Alexander Rheeney, says the newspaper did not do enough to protect the journalist.
"For me to see those pictures on Monday was shocking, and I was so angry because it was obvious to me that nothing was done by colleagues who were living around her but also by the company to identify that one of their senior staff was facing problems."
Our correspondent in Port Moresby Melvin Levongo says Ms Evara lived with her husband in the Post Courier's flats neighbouring other journalists.
He says the police were contacted only after the severe bruising on her body was discovered during the funeral.
A former colleague, Priscilla Maigu, says Ms Albaniel had complained of body aches and bruises a week before her death.
"She confided in me and left most of the valuable information with regards to her injuries and violence, continuous violence against her life. This thing must not go hidden and be buried with her."
Ms Evara's burial was postponed after a court order was obtained to establish the cause of death.
An autopsy was then conducted and preliminary findings are expected to be released within days.
In a statement, PNG's prime minister Peter O'Neill called for men to stand up and prevent domestic violence.
"A man is a coward if he thinks it is okay to hit a woman, these abusers would not have the courage to hit a man who was bigger than they are, but they hit a woman who is smaller,"
Mr O'Neill also called on churches to take the lead in protecting victims and exposing violent men.
The Post Courier's editor Todagia Kelola says reviewing laws regarding gender based violence would help.
"Maybe there should be something that automatically stops the violent husband from taking her back. In many cases it's the survivors who go back again because of so many factors."
He says while his staff had called the police and intervened on behalf of Ms Evara the current law leaves the onus on the victim to lay a formal complaint.
The Port Moresby police have confirmed that there is an investigation under way into Ms Evara's death.
