Of these people, 754 (10 per cent) were secluded at some time during the reporting period. People who were secluded were often secluded more than once (on average 2.2 times). Therefore, the number of seclusion events in adult inpatient services (1,668) was higher than the number of people secluded. Across all inpatient services, including forensic, intellectual disability and youth services, 1001 people experienced at least one seclusion event. Of those secluded, 69 per cent were male and 31 per cent were female. The most common age group for those secluded was 20–24 years. A total of 121 young people (aged 19 years and under) were secluded during the 2015 year, in 289 seclusion events”.29 It should be noted that 72 per cent of seclusion events in 2015 lasted less than 24 hours (ibid.) The prevalence of Secure Care Unit placements in Children and Young Persons’ Care and Protection residences, and in Youth Justice residences The data below is from the Secure Care Unit registers in the Children and Young Persons’ Care and Protection residence and the Youth Justice residence visited.30 As this data is not usually collected centrally, it was extracted especially for this report. Mechanical restraints are no longer used in Care and Protection residences or in Youth Justice residences. Instead, at the time of the visits residences used the Non-Violent Crisis Intervention (NVCI) system of personal restraint, and were planning to move to the Managing Aggression and Perceived Aggression (MAPA) which focuses more on de-escalation techniques. These were not examined in this report.

The duration of stays was as follows: 29 The Office of the Director of Mental Health Annual Report for 2015, Seclusion data.

This definition differs from that of New Zealand's Children, Young Persons and their Families Act 1989, which defines 'child' as 'any boy or girl under the age of 14' and a 'young person' as 'a boy or girl of or over the age of 14 years but under 17 years' (Section 2 of the Act). At the Care and Protection residence visited, at the time of the visit the youngest child was 11 years old, and the oldest was 15 years old. 28
