Tame Iti is appealing against his convictions in the Te Urewera raids case, claiming they are a miscarriage of justice.
Iti was sentenced at the High Court in Auckland in May to two-and-a-half years in prison for his involvement in military style camps in Te Urewera National Park in 2007.
Court documents have been released detailing the grounds for the appeal against the sentence and convictions.
The documents state the sentence and convictions were a miscarriage of justice, pointing to a failure to instruct the jury properly and errors in law during the sentencing.
They also say the sentence was excessive in light of the cases facts, the gravity of the offence and cultural considerations.
Lawyers for Te Rangikaiwhiria Kemara, Urs Signer and Emily Bailey are also lodging appeals.
