This research attempted to investigate the significance of an electronic commerce (EC) use model in small enterprises (SMEs) in New Zealand. The research model hypothesised ten factors as influencing the extent of EC usage significantly in SMEs. The research findings indicated that: relative advantage, cost, compatibility, size, information intensity of product, competition, pressure from suppliers/buyers and CEO’s involvement play an important role on the extent of EC usage. However, support from technology vendors and CEO’s innovativeness did not appear to influence the extent of EC usage.
