Smokers strongly support tighter regulation of the tobacco industry and almost half support an outright ban within a decade, Otago University research has found.
The newly published study found 65 per cent of more than 1300 smokers agreed tobacco companies should be more tightly regulated.
Support for tighter regulation was stronger among Maori, with 70 per cent in favour, and Pacific Islanders, with 74 per cent.
Smokers under financial pressure were also more likely to agree.
Almost half of smokers also supported banning commercial tobacco sales in 10 years if effective nicotine substitutes were available.
