The new forensic Mental Health Inpatient Unit adds an additional 15 beds to the existing Mason Clinic campus, and is a standalone building which functions as an acute admission facility for the existing Maori Rehabilitation Unit, Tāne Whakapiripiri.

The 1770m² unit provides flexible and adaptable accommodation for users that have a mental illness and who have committed a criminal offence, or who are at high risk in the community. It is a modern facility that supports healing and recovery by meeting both the physical and psychosocial needs of its users whilst also providing a safe and positive environment for staff.

The unit contain 15 inpatient beds, 11 for male service users and 4 for female service users; 2 de-escalation/high care rooms with a lounge adjacent a dedicated secure entry. A whare creates the spiritual heart of the building and acts as the admissions room, as well as a multi-functional therapy and meeting space. There are also a variety of shared social and therapy spaces including a gym, an occupational therapy room, dining and lounge spaces and a multi-sensory modulation room.

A courtyard model was applied to the design of the facility to provide an abundance of natural light, good passive staff observation as well as a connection to nature with secure access to outside spaces for service users to engage in.
