Louise Nicholas, ONZM, is a New Zealand campaigner for the rights of women who have been victims of sexual violence. In 1993 she alleged that several policemen had raped her in 1984 and obstructed evidence in the subsequent trials for rape. On 15 December 2007, Nicholas was named New Zealander of the Year by the New Zealand Herald due to her courage during the rape trials of former policemen Rickards, Shipton and Schollum.
Nicholas has taken a role in pushing for the recognition of victim rights, advocating changes to name suppression law after a prominent entertainer received name suppression after sexually assaulting a 16-year-old girl. Nicholas works as a survivor advocate for Rape Prevention Education and has also served on the Tauiwi Caucus of the Executive Committee of Te Ohaakii a Hine - National Network Ending Sexual Violence Together. In 2015, she was the patron of a class of police recruits at the Royal New Zealand Police College and involved in mentoring and advising the recruits during their training.
In 2015 she was the recipient of the Anzac of the Year Award and in the 2015 Queen's Birthday Honours she was appointed an Officer of the New Zealand Order of Merit for services to the prevention of sexual violence.
