These researchers sought to determine changes in smoking habit and psychological addiction among Māori/Pacific and New Zealand European smokers following excise tax increases. In this survey, smokers from New Zealand cities completed questionnaires at three time points before and after two annual excise tax increases from 2012 to 2014. At baseline, the ethnic groups did not differ significantly on measures of cigarettes per day or psychological addiction. However, both measures declined in a linear fashion among Māori/Pacific and NZ European smokers; daily cigarette consumption reduced at a greater rate in Māori/Pacific than NZ European smokers but dependence did not.
