Project Summary

The Central Plant and Tunnel project will replace the existing central plant building at Auckland City Hospital and will create the first section of a proposed tunnel loop for the overall site. The project will address the risks of overreliance on the existing central plant building and provide space for future infrastructure expansion within the new Central Plant Building.

The project includes construction of a six-storey central plant building, tunnel construction, service installation and a series of early enabling works. Construction will take place while the hospital remains operational.

The Central Plant and Tunnel project, with an estimated total cost in excess of NZ$150 million, is the largest project within the NZ$305 million Facilities Infrastructure Remediation Program. The broader program will replace and upgrade critical infrastructure at Auckland City Hospital, Starship Hospital and Greenlane Clinical Centre. Additional works will include lift upgrades, new fire protection systems, new electrical substations and water facilities.
