The Government has declared spending at least $750,000 on the controversial Urewera raids and their long-running sequel - with some saying the final bill could be for millions.
A Weekend Herald request under the Official Information Act asked police, the Crown Law Office and the Legal Services Agency, which provides legal aid, for a running cost covering investigations in the lead-up to the early morning "anti-terror raids" on October 15, 2007, and the court cases against the 18 people charged.
The main trial of 15 defendants - who face firearms charges, with five also facing charges of participating in an organised criminal group - is now expected to begin in February.
The timing is subject to appeals against a decision to have the case heard by a judge alone and on the admissibility of some of the evidence, which is suppressed.
Police have refused to provide a detailed break-down of costs, but have provided an "aggregate figure" of $500,462.
