The Far North has been plunged into another massive power cut, with more than 23,000 homes and businesses without electricity.
The power went out just after 5.20pm with the outage covering the entire southern part of the district, including the Bay of Islands, Kaikohe, South Hokianga and Whangaroa.
According to Top Energy’s outage centre, the fault is on a sub-transmission feeder but the cause is not yet known.

A Kaikohe woman living near the substation said she heard a loud boom about 5.20pm.
She went outside to investigate and saw the doors to a building at the substation appeared to have blown open.
Smoke or water vapour was coming out of the doors.
No one was present at the substation so she called 111.
FENZ sent volunteer fire crews from Kaikohe and Okaihau.
She said three firefighters entered the building wearing protective clothing and breathing apparatus.
There was no sign of fire that she could see.
The fire crews have left but Top Energy workers continue to come and go from the substation on the outskirts of Kaikohe.
It’s exactly the same area that was affected by a huge outage last Friday, just six days ago.

In that case the cause was a tree falling on a 33-kilovolt line near Mount Pokaka, south of Kerikeri, but it was not clear why that caused the Kaikohe substation to shut down, cutting power to more than half the district.
The northern part of the district, including Doubtless Bay, Kaitaia, the Aupouri Peninsula and North Hokianga, still has power, in an apparent re-run of last week’s outage.
