Professor Marewa Glover has worked on reducing smoking-related harm for over 25 years. She has worked as a policy analyst, a co-ordinator of a national tobacco control programme, cessation trainer and, for over 17 years, as a researcher. She has chaired numerous committees and organisations including End Smoking NZ, an independent NGO that lobbied for a harm reduction approach even before electronic cigarettes were introduced. Marewa has over 100 publications reflecting her leadership and support of numerous studies. Her primary focus has been reducing smoking during pregnancy and reducing smoking among Māori, the indigenous people of New Zealand. She has also been a co-investigator on a number of innovative cessation projects and a longitudinal online survey of New Zealand vapers. Dr Glover is the most prominent public commentator on vaping in NZ. She is regularly called by the media and has appeared on NZ’s 60 Minutes in addition to participating in live online and conference debates about vaping. Despite an initial ban on the import and sale of nicotine for vaping imposed by the Ministry of Health, vaping has become established as a common and successful way to reduce or stop smoking in NZ. Marewa, along with a small number of other researchers who early on foresaw the potential of ecigs, have helped make this happen.
