RNZ is challenging a reporting ban which effectively prevents media publishing any information about the fatal police shooting of Rotorua man Shargin Stephens.
Lawyers acting for the public broadcaster have filed papers in the Hamilton High Court asking judges to review a prohibition order by Coroner JP Ryan.
Coroner Ryan issued the interim order last month after an RNZ investigation revealed discrepancies between the police's homicide inquiry into the shooting and the evidence police gave the Independent Police Conduct Authority.
