We also have some concerns about how the police themselves would operate in this. They would need to update all computer systems around the country, and would face, potentially, quite significant costs to do so and roll out a nationally compliant system across New Zealand. This problem is exacerbated by the bill's three-month commencement date. Having to roll out a nationally compliant system in just three months is practicably not achievable, as it would take a significant amount of work to get that under way.
