Judge Mark Perkins today imposed a blanket suppression order over the depositions hearing for 18 people charged in the so-called "anti-terror" raids.
His ruling will prevent the news media from reporting evidence at the preliminary hearing.
It took one and half days to complete the reading of the charges against the accused, who face a total of more than 300 firearms offences.
Among the accused is veteran activist Tame Iti, who faces 27 charges.
Many of the accused sought leave of the court to have the charges read in both Maori and English.
Judge Perkins ordered a blanket suppression of the evidence at the hearing - expected to take a month - after defence lawyers argued it would be prejudicial to their clients.
The crown did not object to media reporting on the evidence.
Police have alleged Iti was running military-styled training camps in the Urewera Ranges, in the eastern Bay of Plenty.
Solicitor-General David Collins last year ruled against an application from police to charge Iti and others under the Terrorism Suppression Act.
