Aki was committed to stand trial today after the Waigani District Court found sufficient evidence he killed his wife on Dec 26 last year at the Kone Tigers oval.
On Sept 19, the court ruled it had enough evidence against Aki who was charged over the murder of his wife on January 5.
A section 96 statement was filed in response to the court's ruling.
After considering that statement, Magistrate John Kaumi ordered the committal of Aki's case for trial today.
He will next appear at the National Court for listing on Oct 31.
The 38-year-old from Tambul in the Western Highlands Province was arrested on January 5 this year and charged for the willful murder of his wife.
He first appeared in court on January 7 and has been remanded at Bomana since.
It is alleged he assaulted his wife at the Kone Tigers oval in full view of the public following an argument on Dec 26, around 3pm last year.
This assault left her with serious injuries which she was hospitalised for at the Intensive Care unit of the Port Moresby General Hospital.
She later died from her injuries.
