Case study: how a New Zealand speeding ad changed global behavior

Overall behavior

Changing ingrained behaviors is one of the biggest challenges in marketing, especially when it involves something as personal and emotional as the way we drive. In 2014, the New Zealand Transport Agency (NZTA), in partnership with Clemenger BBDO, launched “Mistakes,” an innovative awareness campaign addressing speeding on the road.

What made this campaign so impactful wasn't just the ccreativity, but the strategy of Integrated Marketing Communications (IMC)behind the scenes. All touchpoints—from video content to social media outreach—worked cohesively to reinforce a single, powerful message: even good drivers make mistakes, and speeding reduces your margin for error.

Instead of pointing fingers or using fear, the campaign encouraged empathy and reflection. And using the CIM as a foundation, he ensured that the message reached the audience in a way coherent and emotionally compelling, across all platforms and over time.
