RNZ has obtained Ministry of Health documents sent to Costello, in which health officials saythe law she is repealing would have generated health gains for Māori which were five times that of the general population.
The documents say that under the Pae Ora (Healthy Futures) Act the minister and health agencies must be guided by health sector principles, which include improving health outcomes for Māori.
Article Two of the Treaty guarantees “active protection of taonga, including wellbeing”, health officials told Costello.
“The right to be smokefree is entrenched in Te Tiriti o Waitangi,” the advice to Costello said. “Removing measures that were modelled to reverse inequity and improve health and wellbeing by changing the broader environment to support people to quit, to stay quit and to never start to smoke is likely to be viewed as a breach of Te Tiriti.”
The warning, sent in early December, proved prescient as a group of Māori health experts and advocates filed an application with the Waitangi Tribunal in late January, asking for an urgent hearing of their complaint about the Government’s plans to repeal the law.

The Government is pushing on with the repeal anyway, introducing legislation under urgency on Tuesday. It will not be subject to select committee scrutiny, which normally includes hearing submissions from those affected by the law.
Overturning the law scraps moves to reduce tobacco retailers from 6000 to 600, remove 95 per cent of the nicotine from cigarettes and create a smokefree generation by banning sales to those born after 2009.
In the briefings obtained by RNZ, health officials lay out how Māori will be affected by repealing the law, given the Māori population is younger and has much higher smoking rates than non-Māori.
Health officials told Costello that reducing the level of nicotine in cigarettes from about 15mg/g to 0.8mg/g from April 2025 would almost wipe out smoking for the biggest group of smokers: Māori women.
It says that if implemented in 2023, reducing nicotine alone would have reduced daily smoking rates for Māori women from 37 per cent to 10 per cent by 2025 and down to just 1.3 per cent by 2030.
The papers show that smoking is the “leading cause of avoidable morbidity and mortality” in New Zealand, with 12-13 deaths every day caused by smoking or exposure to second-hand smoke.
The policy to create a smokefree generation by banning sales to those born after 2009 was predicted to halve overall smoking rates within 10 to 15 years and be vastly more beneficial for Māori.
“Given higher smoking rates and a younger population, the health gains per person would be five times higher for Māori than non-Māori,” the advice said.
The documents say the smokefree laws would have made a big dent in the disparity of health outcomes between Māori and non-Māori.
“I do not accept what health officials have said about our Treaty of Waitangi obligations, but it’s not appropriate to talk further about that while a claim is before the [Waitangi] Tribunal.”
The modelling in the documents was based on 2019/20 data, Costello said, when the smoking rate was 11.9 per cent. It was now 6.8 per cent.
“In the last four years, 305,000 people have quit smoking - and importantly, one-third have been Māori,” she said. “The number of Māori quitting smoking has accelerated in the last three years and we want to ensure there are targeted programmes and the right tools to ensure that continues.”
Reputational risk to NZ
The documents also warn that New Zealand faces reputational damage from repealing the smokefree law.
Health officials told the minister that the strategy followed in the smokefree law was ranked highest among 25 other international models, in a peer-reviewed study published in the journal Tobacco Control.
“There is significant reputational risk with repealing the smokefree amendments and there is very strong support for the legislation within the health sector,” Costello was told. “Many countries have looked to New Zealand as a leading example in tobacco control.”
Officials said the UK would soon introduce a smokefree generation bill that reflects the New Zealand model and America’s Food and Drug Administration (FDA) was looking at low-nicotine requirements.
