Clouds of vapour streaming from mouths of e-cigarette users signal the changing style of smoking in New Zealand.
But while tens of thousands of Kiwis use the devices, as people seek ways to quit smoking tobacco, planned regulations around their use are still to be introduced.
Latest figures from the Health Promotion Agency's Smokefree website show smoking rates continued to fall.
About 16 percent of adults are estimated to smoke. That is down from 20 percent in 2006/07 and 26 percent in 1996/97. More adults have given up smoking than smoked, and more than 1.9 million New Zealanders have never smoked regularly.
Nearly 80 percent of young people have never had a puff of tobacco.
