Kramer, who had been on suspension for charges of misconduct, was dismissed on Monday by the Leadership Tribunal.
RNZ Pacific's correspondent in PNG Scott Waide said he believes the critical issue was a post that the former Prime Minister Peter O'Neill was soliciting help from the chief justice.
"And that they had submitted fabricated documents that could mislead the court and that the warrant of arrest against Peter O'Neill was defective. Now the judiciary has come back hard on this claim," Waide said.
