The government has refused to release a commission of inquiry report into the disaster, which claimed at least 80 lives in January.
It has ordered a police inquiry into the sinking based on the information presented in the report.
The NGO's chairperson, Ngatau Neneia, told Kiribati News the report's findings could be released on their own instead of the full report.
He said the government should release what it can so families of the victims can know what happened.
When around 30 people died in another ferry sinking in 2009, the Kiribati government never made the report public, President Taneti Mamau told parliament last week.
