Rt Hon JACINDA ARDERN: I'm sure the member is familiar with the idea of stopping someone for speeding or stopping someone for drink-driving. This is no different. There is no sense with any of those that you have no enforcement. There will be enforcement. The decision on how that is operationalised and how that is safely operationalised is not a decision for members of Parliament, and it never has been. It will be operationalised by the police.
