Local tobacco addicts battling to kick the dirty habit are more likely to suffer relapse after being over-extended at work or bombarded with family issues.
New research from Quitline, released to coincide with today's World Smokefree Day celebrations, found stress to be the number one factor in smoker relapses.
About 583,000 or 17 per cent of Kiwi adults were daily smokers in 2011/12, according Health Ministry figures - down from 25 per cent of adults in 2006/07.
In the Rotorua region 1286 smokers attempted to quit smoking last year.
The Quitline study involved in-depth interviews with smokers who had relapsed three months after seeking help from the service.
