The west Auckland-based company which began operating from 2009, went into receivership two weeks ago.
Lyon Electrical and its director, Ben Lyon, was approached for comment but neither have responded.
The company's website shows some of the big projects it's worked on - including the multi-million dollar Park Residences on Auckland's Albert Street.
The website has since been taken down.
NZH Focus understands that the faulty cable has been installed as high up as 16 floors of the 28-storey Park Residences building on Albert Street.
Naylor Love Construction declined to be interviewed but confirmed in a statement that immediate work was underway to replace all electrical cables in the Park Residences.
It's also inspected three other Auckland buildings that Lyon Electrical worked on, finding one of them will also need to replace of its cables.
While there's no immediate risk from the cable - Worksafe is urging anyone who has had work done by Lyon Electrical after July 1st, 2016 to get in touch.
