1. Why Should We Use Breathalysers in New Zealand?
Breathalysers are a key tool in maintaining road safety and reducing drink-driving incidents. In New Zealand, they are used for compulsory breath testing (CBT), which enables police to stop drivers randomly. They help deter dangerous behaviour, provide reliable legal evidence, and support national strategies such as Waka Kotahi’s ‘Road to Zero’. In 2023 alone, over 3 million breath tests were conducted, contributing to a significant drop in road fatalities.
2. What is the Importance of Breathalysers?
Breathalysers are crucial for:
- Promoting road safety by detecting impaired drivers
- Supporting legal enforcement with accurate and admissible evidence
- Providing fast, on-invasive alcohol screening
- Acting as a strong deterrent to drink-driving
- Empowering personal responsibility through self-checks
- Contributing to broader harm-reduction strategies
3. How Do New Zealanders Perceive Breathalysers?
Public perception is mixed. While a majority support drink-driving enforcement, awareness of the legal alcohol limits is low—only about 22% know the correct limit. Belief in the likelihood of getting caught is growing, especially in urban areas with visible checkpoints. Public support for lowering the legal alcohol limit is also strong, with 60% in favour of stricter limits.
4. Can These Perceptions Be Changed for the Better?
Yes, perception can improve through:
- Public education on legal limits and alcohol effects
- More visible and frequent checkpoints
- Community-targeted enforcement, especially in rural areas
- Campaigns reinforcing the risks and penalties of drink-driving
- Policy changes that align with public sentiment
Closing Thoughts
New Zealanders generally support road safety enforcement, but knowledge gaps and uneven perceptions of detection risk still exist. That means:
Clear, frequent public education about legal limits and the risks of driving impaired.
Enhanced and highly visible enforcement to reinforce the belief that drink‑driving will be detected.
Policy alignment with public sentiment, such as lowering adult blood‑alcohol limits.
Focused messaging for under‑reached groups, such as rural communities or younger drivers.
Together, these steps can shift public perception toward stronger trust in breath testing, greater awareness of drink‑driving laws, and ultimately better compliance and safer roads.
