Tame Iti and Te Rangikaiwhiria Kemara have been declined bail while appeals against their convictions and sentences are heard.
Their bail applications were heard at The Court of Appeal in Wellington two weeks ago.
The two Tuhoe activists were jailed for two and a half years in May after being found guilty in the High Court in Auckland of firearms offences relating to the 2007 Urewera raids.
In his decision, released today, Justice John Wild said the pair's applications did not meet the high threshold set for granting bail pending appeal.
"Also relevant to our decision on these two applications is that the time to the hearing of the appeals on 22 August is quite short.
