Is Vaping Better Than Smoking? What NZ Health Authorities Say
If you're a smoker thinking about switching, you've probably asked yourself: is vaping better than smoking, or is it just a different way to get the same risks? It's a fair question, and in New Zealand it's one that health authorities have actually answered. This article pulls together what Health New Zealand, the Ministry of Health, and the Office of the Prime Minister's Chief Science Advisor currently say about vaping versus smoking, so you can make an informed decision based on official guidance rather than guesswork.
So, Is Vaping Better Than Smoking? What the Evidence Shows
According to HealthEd's official "Vaping Facts" resource, published for the Ministry of Health, the position is straightforward: vaping is less harmful than smoking. The same resource is careful to add the important caveat — it is "likely to be much less harmful than smoking," but "it is not harmless" (HealthEd, Vaping Facts, July 2024).
The Ministry of Health's Smokefree Aotearoa 2025 Action Plan puts it in similar terms, stating that "while vaping is substantially less harmful than smoking tobacco, it is not without risk," and frames vaping as an option that gives people who smoke "an alternative at much less cost and risk to health" (Ministry of Health, Smokefree Aotearoa 2025 Action Plan).
The Office of the Prime Minister's Chief Science Advisor has gone further in quantifying this, referencing Public Health England's widely cited estimate that nicotine vaping products are "at least 95% less harmful than cigarettes, although estimates vary," while also noting that the World Health Organization considers vaping aerosol "likely to be less toxic than cigarettes" without enough evidence yet to put an exact number on it (OPMCSA, Hot topic: Smoking and vaping, 2024).
Why Vaping Is Considered Less Harmful Than Smoking
The core reason cited by these authorities is combustion. Cigarette smoke contains thousands of chemicals produced by burning tobacco, including dozens of known carcinogens. Vaping devices heat an e-liquid rather than burning it, which HealthEd notes means vapers are exposed to far fewer harmful chemicals than smokers. Nicotine itself, while addictive, "doesn't cause cancer or related illnesses" according to the same HealthEd guidance — it's the combustion by-products in cigarette smoke that drive most of smoking's serious health harms.
This is the basis for New Zealand's harm-reduction approach to vaping: rather than treating it as equivalent to smoking, it's treated as a significantly less harmful option for people who already smoke and are trying to quit or cut down.
Vaping Is Not Risk-Free
None of this means vaping gets a clean bill of health. The OPMCSA's advisory notes that more than 80 chemicals have been detected in vaping aerosol and that vaping has been associated with respiratory symptoms in some users, while cautioning that the long-term effects of vaping are still not fully understood, since the products haven't been in widespread use for long enough to study lifetime outcomes. HealthEd makes the same point plainly: vaping "hasn't been around long enough to know the risks of long-term use."
That's why every official source is consistent on one thing: vaping is a tool for people who already smoke, not something to take up if you don't. HealthEd states this directly — "If you don't smoke, don't vape" — and the OPMCSA echoes it, saying the safest approach for non-smokers is to avoid vaping altogether.
Who Vaping Is (and Isn't) For
Based on this official guidance, vaping is best understood as a switching tool for adult smokers, not a lifestyle product for non-smokers or young people. If you currently smoke and are looking for a less harmful way to get your nicotine while you work on quitting altogether, the evidence supports vaping as a reasonable option to discuss with your doctor or try for yourself. If you've never smoked, the advice from every NZ authority cited above is to leave vaping alone.

Staying On Top of the Rules
Vaping in New Zealand is also a regulated product category, with rules covering where you can buy, advertise, and use vapes. If you want the full picture of what's currently in force, our breakdown of NZ's current vaping laws covers the detail.
Frequently Asked Questions
Is vaping 95% less harmful than smoking?
That figure comes from a 2018 Public Health England estimate, referenced by New Zealand's Office of the Prime Minister's Chief Science Advisor, which states vaping products are "at least 95% less harmful than cigarettes, although estimates vary." It's a widely cited figure rather than an exact, universally agreed number, but it reflects the broad consensus that vaping carries substantially lower risk than smoking.
Does New Zealand's Ministry of Health recommend vaping to quit smoking?
The Ministry of Health's Smokefree Aotearoa 2025 Action Plan positions vaping as a less harmful alternative that can help people who smoke move away from tobacco, while being clear that it is "not without risk." It's framed as an option for smokers trying to quit or reduce their tobacco use, not as a general recommendation for everyone.
Is vaping safe for someone who has never smoked?
No. Every official New Zealand source referenced in this article is consistent on this point — vaping is intended for existing smokers, and people who don't smoke are advised not to start vaping.
This article is general product information, not medical advice, and is intended for existing adult vapers and smokers looking to switch. All products sold by NZ Vapez are R18+ — proof of age is required at checkout and on delivery.
