Urewera activist Tame Iti has tweeted that he will be appealing his conviction on firearms charges over alleged military camps to the Supreme Court.
Iti, along with Te Rangikawhiria Kemara, Urs Signer and Emily Bailey, were found guilty in March by a jury at the High Court in Auckland of unlawfully possession of firearms during the 2006-2007 camps.
Iti and Kemara were given jail terms of two and a half years, while Signer and Bailey were given home detention sentences.
Iti's lawyer Russell Fairbrother indicated a Supreme Court appeal was possible after the Court of Appeal dismissed the quartet's appeal against their convictions and sentences, and a tweet on Thursday said he would be going to the country's highest court.
"After much consideration... I WILL be submitting an appeal to the supreme court... third time's a charm," the tweet said.
Iti cannot tweet from prison but relays tweets to his whanau via a phone at the prison.
Kemara's lawyer Jeremy Bioletti said earlier this month that his client would be appealing to the Supreme Court, while Signer and Bailey have indicated they are considering an appeal.
The High Court jury could not reach a decision on the charge of membership of an organised criminal group and the Crown chose not to proceed to a second trial.
