The study considers women as witnesses in New Zealand's colonial courts from c. 1840 to 1900. An analysis of women as witnesses adds another dimension to what is known about the everyday but often compelling presence of women in New Zealand's colonial courts. In 1840 British law was formally implemented in Aotearoa/New Zealand. The law's institutional structures would soon follow. In 1841 the Supreme Court was established followed by the Resident Magistrate Courts in 1846. The courts were a part of formal British governance. While women were excluded from serving as judges, barristers, solicitors, court officials and jury members, they did appear before the courts as victims, defendants, spectators and witnesses. Being a witness was the only form of verbal participation women could undertake in the court processes during the nineteenth century. Existing scholarly work has tended to concentrate on women appearing in the courts in the nineteenth century as victims or defendants. This study explores the complex agency of women using the law and as active participants in its deliberations. Four substantive chapters consider women as witnesses in cases involving petty offences, violent crime. civil cases and the Native Land Court and finally cases of divorce, bigamy and action of breach of promise of marriage. Courts were significant public places in colonial New Zealand. They were places where disputes were settled, grievances could be aired, conduct was put on trial and order was maintained. A long established element of the legal tradition was that unprejudiced and fair justice could only be assured if the courts were open and public spaces. Thus, the witness stand was a place where women had a public voice.
