A world-first study of electronic cigarettes needs more guinea pigs.
Researchers at Auckland University's clinical trials research unit are studying whether e-cigarettes can help smokers to quit.
E-cigarettes are battery-operated vaporising devices now widely available from shopping malls, the internet and supermarkets.
The study aims to find out if they actually help smokers quit and how they compare with nicotine patches, lead researcher Associate Professor Chris Bullen says.
Called Ascend, the study is the largest trial of e-cigarettes for quitting conducted so far anywhere in the world.
Researchers are hoping to recruit about 650 people from the Auckland region into the study.
"So far we have about half the number of people we need," Dr Bullen says.
"So we're inviting people who want to quit smoking, who are at least 18 years of age and in stable health to call us about taking part."
