Power outages in Western Springs have caused the closure of Auckland Zoo and Western Springs College.
A spokeswoman for Vector said it was made aware of a network fault in the area at 4am today.
The fault had been repaired at 8.45am this morning, but part of the fault has since returned.
The spokeswoman said teams would now return to the fault site and work to repair it.
She said the area around Motions Rd would be affected by this work, with power being out for at least half an hour.
