A further $1.63 million has been paid to the lawyers of 13 other accused whose charges from the October 2007 raids were dropped last year, when the Supreme Court ruled the evidence against them was gathered unlawfully.
Figures released by the Crown Law Office show nearly $119,457 was charged for the time of the three prosecutors for the trial. This is on top of the $322,412 spent on prosecutors to work on the case up until the trial started in mid-February. The police have provided an "aggregate figure" of $500,462.
The case was taken through the District Court, High Court, Court of Appeal and the Supreme Court, which increased the total cost.
The total of $3.88 million makes it one of the country's most expensive cases. In terms of legal aid paid, only the $3.3 million paid in the David Bain trials and appeals is higher.
The Crown could seek a second trial for Iti, Signer, Kemara and Bailey after the jury was unable to reach a verdict on the charge of participating in an organised crime group. That decision will be announced soon.
The four will be sentenced on May 24 on the firearms charges the jury found them guilty of.
