The purpose of this paper is to examine the effect of corporate governance practices of small cap companies have had on their financial performances. Previous studies have mainly examined governance practices of larger corporations. This analysis focuses on the governance variables that have been highlighted by the New Zealand Securities Commission governance principles and guidelines and also on the governance variables that are supported in the literature as providing an appropriate structure for the firm in the environment in which it (...) operates. The data for 71 small cap companies listed in New Zealand over a five-year period from 2001 to 2005 was analysed. Pooled data, OLS and 2SLS regression techniques were used and Tobin's Q, ROA and OPINC were used as the dependent variables. The evidence does support the hypothesis that the existence of board independence and audit committee has enhanced firm financial performance, as measured by Tobin's Q. (shrink)
