Corrections - Annual remand prisoner throughput for Year ended June 1999–2023

Remand: Committal to custody.
Remand prisoner: When someone is held in custody while they wait for their trial or sentencing it’s called being on remand. A remand prisoner could be held in police cells, court cells, psychiatric facilities or in prison (but only the ones in prison are included in this data). People on remand are kept separate from sentenced prisoners, in units or wings only for remand prisoners. Any time spent on remand is taken off a person’s total sentence time.

This data measures distinct remand periods, not unique offenders, that is, the number of new remand period starts within a financial year. If an offender starts more than one remand period within a year then the offender is counted more than once.
A person is counted once for the most serious offence category for which they were prosecuted.
Information on the sex and ethnicity of an offender is recorded by Corrections. Age is calculated based on the birth date as collected by the prosecuting authority (mostly New Zealand Police) at the time a person is arrested or prosecuted.
A person on remand can be counted more than once if they are bailed between episodes of custodial remand. However, if the bailed period is less than 48 hours, the two custodial remand episodes are joined.
A prison sentence that is subsequently cancelled on appeal is still included in these statistics, as the offender had spent the time in prison.
The length of remand is based on the actual time spent in prison, not the court-imposed length.

This remand data only counts those remanded in a Corrections prison. If they are temporarily outside the prison (e.g. police cell, psychiatric facility), they are not counted (even though they are technically still on remand).
