NZTA spokesman Andy Knackstedt denied the ad suggested Maori were more likely to drug-drive than other ethnicities.
It was the third instalment of a series which attempted to spread the message about the dangers of drug-driving throughout the community.
The previous ad, called Expert Opinions, featured dairy owners, fish and chip shop workers and a couple who owned a bakery talking about their experiences dealing with stoned people. That ad, which targeted drivers in their 30s and 40s, had attracted complaints because it had featured all Pakeha drivers.
"Both ads are sending the same message to different parts of the same very broad audience," Mr Knackstedt said. "Our research clearly showed that in order to reach Maori with a message that would be seen as credible, that message would have to come from a credible source via a trusted medium and in an authentic way."
