Auckland South Corrections Facility


The construction of Wiri Prison was a public-private partnership between the government and several major companies named ‘SecureFuture’.

The new 960 bed prison comprises of 32 buildings in total including three house blocks and 10 residence buildings.

Serco has the contract to operate the prison for 25 years, and with this in mind the design of the facility was future-proofed allowing practices, programs and systems to keep pace with best practice thinking as these develop.

Mechanical services were supplied to 30 of the buildings which largely consisted of ventilation supplied via supply and extract fans, AHU's, split air-conditioning units and FCU's.

Heating is supplied to several buildings via gas fired heating hot water boilers serving the FCU’s & AHU’s. There are two air cooled chiller units in the gate house which feed a chilled water system to three other buildings through a below ground pipework system, which serve the FCU’s.

A below ground gas ring main covers the whole site feeding the heating hot water boilers, domestic boilers, kitchen and gas fired radiant heaters throughout the industry buildings.

The whole mechanical system is controlled by a full site BMS in conjunction with the mechanical electrical trade.
