All but one of the 20 people arrested during nationwide police raids last year will appear in the Auckland District Court on Monday for a depositions hearing.
The raids on 15 October focused on the Bay of Plenty settlement of Ruatoki and a suspected training camp in the Urewera ranges. Properties were also searched in Auckland, Christchurch, Hamilton, Palmerston North and Wellington.
Some of the accused initially faced charges under the Terrorism Suppression Act but those were thrown out when the Solicitor General determined there was insufficient evidence and the legislation was flawed.
They now face charges including illegally possession of firearms, ammunition and explosives.
The Tuhoe iwi says it's confident the Crown's case will be found wanting.
