Prevalence and harm of sexual violence
2.1This chapter presents some of the statistics relating to sexual violence in New Zealand, taking care to highlight the limitations of the data available.
2.2There are difficulties in painting an accurate statistical picture, which are discussed below. However, the sexual violence sector estimates that one in four women and one in eight men are the victim of sexual violence in their lifetime.
2.3The 2014 New Zealand Crime and Safety Survey (NZCASS) concluded that two per cent of adults were the victims of one or more sexual offences in 2013, and according to earlier NZCASS studies, the number of sexual offences per 100,000 adults in 2005 was six, while the number of sexual offences per 100,000 adults in 2008 was four.
2.4A further figure provided in the NZCASS in the last three surveys is the number of sexual offences (not expressed as a percentage). In 2005 there were 317,000, in 2008 there were 285,000 and in 2013 there were 186,000 sexual offences.
