As elsewhere in the world, academic misconduct is a serious problem in Aotearoa. Yet, beyond the occasional newspaper headline, we know relatively little about the extent of the problem here or the factors associated with it. Consequently, our educational leaders and practitioners are left under-informed as they seek to address the problem and promote academic integrity. To help provide the knowledge and insights needed to craft good policy and best practice, the Research on Academic Integrity in New Zealand (RAINZ) Project--a research collaboration involving eight tertiary institutions--was founded in 2021. In the second semester of 2022, the RAINZ Project launched the first-ever nationwide survey of undergraduate students' perceptions, attitudes, and behaviours related to academic integrity. Results from this survey, which was completed by undergraduates (N = 4493), indicate that most students (approximately two-thirds) reported engaging in at least one form of academic misconduct in the past year. As hypothesised, students' perceptions (of the institutional climate and peer norms) and moral attitudes (related to cheating) were significantly associated with their engagement in academic misconduct. Details of these results as well as their implications for policy and practice are discussed.
