Tipping has not been common practice in New Zealand, and was formerly actively discouraged. The influence of international travelers, particularly from the United States, seems to have contributed to the custom's becoming more prevalent. At the time of this study, tipping in New Zealand remained a voluntary extra payment given for genuinely superior service. Few table servers counted on tips and sincerely appreciated receiving them. An increase in tipping is not without consequences, however. The service relationships involving managers, servers, and customers are altered by the expectation of tips. In addition, dividing tip pools sometimes causes friction among workers.
