New Zealand's experience, in its own region and beyond is that credible, informal and tradition-based justice systems have a demonstrated role in establishing accountability. In post-conflict societies, it is often informal justice mechanisms that are the most accessible for justice, mediation and conflict resolution. While some informal and traditional systems struggle to adequately address women's needs due to inherent gender biases, examples from Africa show the value of local efforts to transform such institutions in a manner that allows for the full participation for women.
