Undergrounding the power to make way for 3,000 new homes in Flat Bush, Auckland was a challenge we have relished in the past year. Our contracting services teams worked over 100,000 hours collectively to underground two 220kV transmission lines, making way for the housing development to take place.

This project involved the installation of over 14.4km of 220kV cables, along with supplying and installing six 220kV cable termination structures and six joint bays.

The multi-discipline team working on the project comprised a mix including civil, electro-fusion and horizontal directional drilling contractors, PE pipe installers, mechanical fitters, cable layers, team leaders, supervisors and project managers. A purpose-built onsite site office housed our team and civil contractors, alongside our customer Taihan and Transpower.

The project was completed in February and is another great example of our teams coming together to deliver great customer outcomes in a safe way - making a tangible difference in developing the future communities of New Zealand’s largest city.
