About EASE

EASE is Aotearoa's International Tobacco Control ( ITC ) project, a health study which aims to support Aotearoa New Zealand's Smokefree 2025 goal. It generates evidence to inform policy and actions to help people become and stay smokefree. It is funded by the Health Research Council and runs from 2020–2025.

The study surveys around 1,600 adult New Zealanders who smoke or who have recently quit and follows them over time. Our aim is to understand how tobacco-related policies and initiatives affect people who smoke and influence their behaviour. We also want to get participants' views about possible future policies to help achieve the Smokefree Aotearoa goal.

Māori, Pacific peoples, and young adults are over‑represented among people who smoke, so the EASE study has a particular focus on these groups, asking their views and finding out what works for them. We want to make sure there are no groups left behind on Aotearoa's journey to become a smokefree nation.

The project team includes Māori and Pacific researchers who are leading the ethnic-specific aspects of the research.

The EASE study is part of the ITC (International Tobacco Control Policy Evaluation) project. It is a continuation of previous ITC New Zealand projects:

It is also part of the Whakahā o Te Pā Harakeke Programme which is led by the ASPIRE 2025 Research Centre, based at the University of Otago:

About the ITC (International Tobacco Control) Policy Evaluation project

ITC logo finalThe International Tobacco Control Policy Evaluation Project (the ITC Project) is an international study of tobacco use that follows smokers and recent quitters over time. Its overall objective is to measure the impact of tobacco control policies (e.g. plain packs, smokefree legislation, ad campaigns) and identify the determinants of effective tobacco control policies.

The ITC Project is a collaborative effort with international health organisations and policymakers in 31 countries so far, inhabited by >50% of the world's population, >60% of the world's smokers, and >70% of the world's tobacco users. New Zealand has been part of this international team since 2006.

Is the study associated with tobacco or vaping companies?

No. The study is not associated with any commercial interests and receives no funding from the tobacco or vaping industries or associated organisations.

The Wave 3 survey for the EASE study was conducted from November 2020 to February 2021. A total of 1277 people participated in the survey.

The Wave 4 survey for the EASE study was conducted from October to December 2022. A total of 1579 people took part in the survey.

Findings from the survey have been used to inform the Government's Smokefree 2025 Action Plan and related legislation and regulations. Future survey waves will help to evaluate the impact of New Zealand's policy initiatives, and as such EASE findings are of great local and international importance.
