CAT/C/NZL/CO/6 (g) Developing and implementing a comprehensive national sexual violence prevention strategy by further intensifying community-based approaches to combating violence against women, with the involvement of all stakeholders. Trafficking in persons 12. While welcoming the progress made to combat trafficking in persons (see para. 6 (c) above), human trafficking remains a matter of concern for the Committee, as the State party reportedly continues to be a destination country for foreign men and women trafficked for the purposes of forced labour and sex and a source of children trafficked within the country for the purpose of sex. The Committee notes that, despite the current situation, only a small number of trafficking cases have recently been brought forward under its anti-trafficking legislation (arts. 2, 12-14 and 16). The State party should: (a) Vigorously enforce the existing legislative framework; promptly, thoroughly and effectively investigate cases of trafficking in persons and related practices; and prosecute and punish those responsible with appropriate penalties; (b) Enhance international cooperation to combat human trafficking, including through bilateral agreements, and monitor the impact of such cooperation; (c) Provide specialized training to public officials, including on the Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children, supplementing the United Nations Convention against Transnational Organized Crime; (d) Adopt effective measures to prevent and investigate acts of trafficking, prosecute and punish those responsible and conduct nationwide awareness-raising and media campaigns about the criminal nature of such acts; (e) Provide effective remedy to all victims of the crime of trafficking; (f) Provide the Committee with comprehensive and disaggregated data on the number of investigations carried out, prosecutions initiated and sentences handed down for human trafficking and on the provision of redress to the victims. Arrangements for the custody and treatment of persons deprived of liberty 13. Bearing in mind its previous concluding observations (see CAT/C/NZL/CO/5, para. 9) and the report of the Subcommittee on Prevention of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment on its visit to the State party, the Committee is concerned at reports that, despite remedial measures taken by authorities, overcrowding remains a problem in many places of detention. The Committee is concerned at reports that, in a number of such places, the material conditions and health-care services, in particular mental health-care services, are inadequate. The Committee is concerned at provisions of the Corrections Amendment Act 2013 authorizing the mandatory stripsearching of prisoners in a broad range of circumstances. Finally, the Committee is concerned at information received that the rate of violence between prisoners and the rate of assaults of prisoners on guards is higher in the privately run Mount Eden Corrections Facility than in other comparable public correction facilities (arts. 2, 11 and 16). The State party should strengthen its efforts to bring the conditions of detention in all places of deprivation of liberty in line with relevant international norms and standards, including the United Nations Rules for the Treatment of Women Prisoners and Non-custodial Measures for Women Offenders, in particular by: 4
