The Maori Law Society says uncertainty and lack of clarity surrounding the Terrorism Suppression Act is causing some communities to continue fear being raided by police.
Terrorism suppression legislation has only been used once - in the Urewera raids of 2007.
But the Solicitor-General ruled police prosecution couldn't apply the Act in court.
A review of the law was started by the Government - but was never finished.
Maori Law Society co-president Liana Poutu says that without an overhaul of the Terrorism Suppression Act, tangata whenua are left watching their backs.
She says Maori have concerns because the only example of the Act being used is a shocking one.
Ms Poutu says while there's uncertainty and a lack of clarity with the piece of legislation, Maori are wonder if they are next to be targeted under the Act.
