The city end of Aberdeen and Palmerston roads, along with sections of Berry, Disraeli and Cobden streets have been without street lighting for the several nights this week.
A council spokesperson said Electrinet has told them that there was a large circuit fault in that area.
Repairs were to have been completed on Tuesday.
The street lights were still out that night.
No update on the situation was available when the Herald went to print last night.
