Lines company Vector said an unplanned outage affected a stretch of Auckland from downtown’s Fort St up to some University of Auckland properties and across into Parnell.
The company alerted people by text just after midday but said power was restored at about 1.15pm.
Some businesses on Parnell Rd this afternoon confirmed the outage had affected them.
However, an apartment building on the Parnell-CBD boundary shown by Vector’s outages map as being in the affected area had electricity as usual.
Vector in its text alert said anybody with medical dependency issues should call 111.
