New Zealand will phase in a near-total tobacco ban from next year.
Legislation passed by parliament on Tuesday means that anyone born after 2008 will never be able to buy cigarettes or tobacco products.
It will mean the number of people able to buy tobacco will shrink each year. By 2050, for example, 40-year-olds will be too young to buy cigarettes.
Health Minister Ayesha Verrall, who introduced the bill, said it was a step "towards a smoke-free future".
