The man accused of murdering Constable Matthew Hunt will argue for name suppression in the Court of Appeal.
The 24-year-old was refused name suppression in the High Court last week but kept his identity secret until this afternoon to give him time to consider an appeal.
RNZ has now received confirmation the accused has filed an appeal that will be heard in the Court of Appeal later this year.
On 31 July, Justice Venning declined to extend name suppression for the accused but granted a request from his legal team to ban publishing pictures of him at this stage.
The 24-year-old man denies charges of murder, attempted murder and dangerous driving causing injury.
RNZ, Stuff and NZME jointly opposed the application and were legally represented in court.
The Crown also opposed the application.
Constable Hunt was shot, and another officer injured, during a routine traffic stop in West Auckland on 19 June.
Earlier in July, 30-year-old Natalie Jane Bracken was publicly identified as the woman charged with being an accessory to murder after the fact after losing her name suppression bid.
Both defendants are due to stand trial in July next year.
Hunt, 28, was the first New Zealand police officer to die in the line of duty in 11 years.
His funeral was held at Eden Park this month.
