[2] In January 2021, former New Zealand First Member of Parliament Darroch Ball became the co-leader of the Sensible Sentencing Trust alongside Jess McVicar.
In a press release, the Trust described the proposed law as "weak and watered-down" and took issue with the Government to wipe 13,000 former strike warnings and its higher threshold for crimes that would fall under the three-strikes legislation.

Following public consultation at the select committee stage, the New Zealand Cabinet agreed to lower the threshold for first strike offenses from 24 months to 12 months and to activate three strikes warnings issued under the previous Sentencing and Parole Reform Act 2010 legislation where offenders met the new thresholds under the new legislation.
