Our recommendation

The New Zealand Police need to improve how they assess how effectively and efficiently they enforce drink-driving laws. We recommend that the Police decide on a consistent and clear set of national indicators to measure how effectively and efficiently they enforce drink-driving laws, and:

• monitor those indicators consistently over time to better understand results and identify where they can make gains;
• use the understanding this gives them to enforce drink-driving laws more effectively and efficiently; and
• use those indicators to report publicly and consistently on how effectively and efficiently they enforce drink-driving laws over time.
