This study examines the impact of boards of directors on corporate financial performance. The aim of the research is to explore the relationship between the number of people on the board of directors and corporate financial performance. . Five retailer companies operating in New Zealand were selected. Regression analysis was used to explore the relationship between size of the board (independent variable) and the average share price (dependent variable). A quantitative approach was adopted for this study. Findings revealed that there is a positive association between the board size and the corporate financial performance. The study suggests that small board size should be encouraged, and the composition of independent directors should be sustained and improved upon to enhance corporate financial performance. The board of directors plays a vital role influencing the firm’s strategy and to authorise decision making.
