Figures exclusively revealed to 1 NEWS show the sexual violence court pilot is slashing trial wait times from two years to an average of just eight months.
The new courts in Auckland and Whangārei have been active for the past 18 months and Chief District Court Judge Jan-Marie Doogue wants to see it become permanent.
"It's very encouraging to think that of those 300 almost all of them have got through in and out in under eight months," Judge Doogue told 1 NEWS.
Victims Advocate Louise Nicholas has also applauded the new system.
"That is a huge, huge step forward. I've had survivors that have been in the criminal justice system four years waiting for a trial," she said.
The report also recommended judge alone trials, but that requires a law change.
Specialist training has been given to 52 district court trial judges with plans to make the sexual violence court mandatory.
Results are being released to the Ministry of Justice this week.
