This reinforced supply lines to Auckland and allowed for the large amount of new geothermal generation that was expected in the Taupo region over the following 5â7 years. A separate switching station, designated Whakamaru North, was built approximately 800 metres (2,600 ft) from the current substation as the terminal station for the new line, with short tie-lines connecting to the existing substation.

The foundation rock turned out to be deeply cracked and filled with clays rendering it partially porous. Shafts were sunk into the rock and this allowed the clay to be cleared and cement grout was later forced into the rock which was then back-filled with concrete.
