Waikeria Prison Expansion

Department of Corrections · Waikato

Expansion of Waikeria Prison in Waikato, set to become New Zealand's largest corrections facility. A 596-bed high-security development, including a 96-bed Mental Health and Addiction Service, opened in 2025. A further 810-bed extension, funded within Budget 2024's $1.9b four-year Corrections capital allocation, is due by late 2029, taking the site toward roughly 1,900 beds. Corrections has not published a standalone cost for the extension.

Election risk assessment

Under construction and funded within Budget 2024's Corrections capital, but prison expansion is ideologically contested: the Greens and Te Pati Maori favour reducing the prison population rather than adding beds, so a change of government could slow the later stages.
