Life imprisonment and preventive detention are both indeterminate sentences where the offender is not eligible for parole until he or she has served 10 years in custody.
Preventive detention is available for repeat sexual and violent offenders.
Imprisonment sentences are determinate sentences that can be imposed at the discretion of the court up to a maximum period expressed in legislation. Corrective training is a three month custodial sentence with a rigorous regime for young people aged 16 to 19. Information is presented in this chapter on the types of offences resulting in custodial sentences and the lengths of these sentences. As well as this, information is given on the average number of males and females in prison at any one time over the decade, and on the number of cases involving a remand in custody in 1999. The Criminal Justice Amendment Act 1993 amended the principal Act so that courts can now impose a community-based sentence cumulative on a sentence of imprisonment of 12 months or less.
