Public health experts have confirmed that New Zealand’s adult smoking rates are falling at a record pace due to the adoption of smoke-free alternatives. Published in The Lancet Regional Health, the study shows a fivefold acceleration in the annual decline of smoking since 2018, coinciding with the rise of vaping.
The study, co-authored by University of Auckland professors emeritus Robert Beaglehole and Ruth Bonita alongside independent health advisor Ben Youdan, analyzed New Zealand’s tobacco control data over two decades. Their regression analysis confirmed that the post-2018 period represents a statistically verified acceleration in decline compared to earlier trends.
| Time Period | Annual Rate of Smoking Decline | Primary Policy Drivers |
|---|---|---|
| Before 2018 | 3.5% | Traditional measures (taxes, smoke-free spaces, graphic warnings) |
| 2018 – 2023 | 17.9% | Rise of vaping and official endorsement of harm reduction |
Beaglehole, a former director at the World Health Organization (WHO), noted that traditional tobacco control measures initially lowered smoking rates, but at a speed that would have missed the country’s “Smokefree 2025” target by decades. The rapid decline occurred only after the Ministry of Health endorsed vaping as a cessation tool around 2019.
The authors emphasized that public health policies must distinguish between nicotine and combustible tobacco. Because nicotine itself does not cause smoking-related illnesses, reducing exposure to smoke from burning tobacco should remain the primary goal of health regulators.
Currently, New Zealand’s adult smoking rate is under 7%, mostly concentrated among older adults and the indigenous Maori population. However, harm reduction strategies have helped the Maori smoking rate cut in half over six years. The researchers concluded that future progress requires targeted, equity-focused support and regulations that align with the specific risk level of each nicotine product.
