Four police officers will stand trial accused of bashing an Aboriginal man at Ballina on the New South Wales north coast.

A total of 25 charges were laid against six officers after an incident involving Corey Barker in January 2011.

The 23-year-old was falsely charged with assaulting a constable, until video footage from Ballina police station showed him allegedly being bashed and left handcuffed in a cell while he was injured.

The assault charge against Mr Barker was dropped after a magistrate watched the video.

After a Police Integrity Commission (PIC) misconduct investigation, six former and serving officers were charged with numerous offences that include common assault, lying under oath and fabricating evidence.

In Downing Centre Local Court four of the men - Constable Lee Walmsley, Constable Ryan Eckersley, former Sergeant Robert McCubben and Senior Constable Mark Woolven - were committed to stand trial after waiving their right to a committal hearing.

The court heard a fifth officer will also waive his right to a committal hearing.

The men are due back in court later this year. Their trial will be in 2015.

The PIC report ruled that the treatment of Mr Barker by officers was "violent".

The four officers are pleading not guilty.
