In this paper, gender differences in Web 2.0 usage by postgraduate students in New Zealand are presented. 84 postgraduate students drawn from two different convenience samples were surveyed to discover the extent to which they used and were familiar with Web 2.0 applications. According to Cuadrado-García, Ruiz-Molina and Montoro-Pons (2010, p. 367), "men and women differ in their interaction with technology". In this study, gender differences in the use of different Web 2.0 applications and technologies have been considered. Whilst findings from this study are limited by the way in which the populations were sampled, the sample size and having a majority of international students with English as a second language, it is interesting to note that there were only minor differences between the ways in which male and female postgraduate students use Web 2.0 applications.
