CAT/C/NZL/CO/6 custodial staff in places of deprivation of liberty. The Committee recommends that the State party provide more stringent instructions to law enforcement personnel authorized to use electric-discharge weapons and to strictly monitor and supervise their use through mandatory reporting and reviews. Non-refoulement and mandatory immigration detention 18. While welcoming the information provided by the State party on the comprehensive system put in place to assist asylum seekers, the Committee is concerned at bills introduced into Parliament that would reduce some of the existing statutory standards for the protection of asylum seekers and undocumented migrants. It is particularly concerned at the Immigration Amendment Act 2013, which, inter alia, allows the detention of “mass arrival groups” of asylum seekers for up to six months and at policies and practices currently applied to persons who arrive in the State party through irregular channels (arts. 2, 3, 11 and 16). The State party should adopt the measures necessary: (a) To ensure full compliance with its obligations under article 3 of the Convention in respect of non-refoulement; (b) To ensure that detention should be applied only as a measure of last resort, when determined to be strictly necessary, in a manner proportionate to each individual case and for as short a period as possible; (c) To establish, in case it is necessary and proportionate that a person should be detained, statutory time limits for detention and access to an effective judicial remedy to review the necessity of the detention; (d) To ensure that stateless persons whose asylum claims have been refused and refugees with adverse security or character assessments are not held in detention indefinitely, including by resorting to non-custodial measures and alternatives to closed immigration detention; (e) To identify as early as possible all victims of torture among asylum seekers and other persons in need of international protection and provide them with priority access to the refugee determination procedure and to treatment for urgent conditions; (f) To provide a thorough medical and psychological examination and report, considering the procedures set out in the Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol), by adequately trained independent health experts, with the support of professional interpreters, when signs of torture or trauma have been detected during personal interviews and, on that basis, provide access to immediate rehabilitation services; (g) To provide regular training on the procedures established in the Istanbul Protocol to asylum officers and health experts participating in the asylum determination procedure, including training on detecting psychological traces of torture and on gender-sensitive approaches. Redress, including compensation and rehabilitation, for victims of torture 19. While welcoming the commitment of the State party to provide compensation to victims of historic claims of abuse, the Committee is concerned at the fact that victims have not been awarded with full redress, including compensation and rehabilitation, as prescribed by general comment No. 3 (2012) on the implementation of article 14 by States 7
