Inmates accused over the riot over New Year at Waikeria Prison will keep their identities secret for now.
A group of 17 face charges including intentionally damaging by fire, using weapons to unlawfully enter parts of the prison and unlawfully damaging property.
Many of the co-accused appeared in Hamilton District Court today but were remanded in custody without entering a plea.
The riot consumed the prison's high-security complex from December 29 to January 3.
It was the biggest prison riot in New Zealand for decades.
