The purpose of this dissertation project is to test the effects of ethnicity as a moderating variable for the relationship between a follower’s perceptions of a leader’s authentic leadership behaviours and the employee’s job satisfaction. Two new measures were constructed from parts of the Authentic Leadership Questionnaire and the Abridged Job Descriptive Index. These were administered as a survey to an opportunistic, though representative, sample of New Zealand adults working in small to medium-sized businesses. The results confirm that followers’ perceptions of authentic leadership are significantly and positively correlated with their job satisfaction. Ethnicity did not demonstrate a moderating effect on this relationship. Both of the scales developed for this study proved to be reliable measures of a follower’s perceptions of authentic leadership and their job satisfaction respectively.
