Immediate work is underway to replace dangerous electrical cables that have been fitted in multiple Auckland buildings.
Worksafe has confirmed seven buildings, mainly businesses, have been affected, in having the faulty cable put in.
A warning was issued to all electrical workers nation-wide yesterday to be on alert about the particular TPS cable.
Tests carried out on the cable showed that its insulation is likely to become brittle and may fracture within just a few years of being installed, resulting in an increased fire and shock risk.
Masters Electricians has named the company responsible - Lyon Electrical Limited - for importing the faulty cable in July last year, and then both selling, and in some cases fitting, it in several buildings.
