This work investigates the internal social structures, daily realities, and psychological impacts of incarceration within the New Zealand prison system during the late 1970s. Greg Newbold, a former inmate turned academic, utilizes his personal experience of a five-year sentence to provide a sociological analysis of prison life. He examines the informal hierarchies, the influence of gang culture, and the systemic failures of rehabilitation efforts, offering a critical perspective on the penal environment from the viewpoint of those living within it.

The text is regarded as a foundational sociological account of the New Zealand penal system, valued for its rare combination of lived experience and academic rigor. Its candid documentation of prison culture provides a significant resource for students of criminology and those interested in the history of corrections in the region.
