Repair teams have fixed a tripped circuit, Transpower says, after a lightning strike cut power to at least 50,000 people in the eastern and central North Island - and work is about to start on switching the power back on.
Meanwhile, a severe thunderstorm warning is in place in several areas.
One lightning strike had tripped the power supply to Hawke's Bay, Gisborne and Wairoa, the company said: a transmission tower had been hit.
A Transpower spokesperson said workers have been working to restore power as soon as possible, although it was not possible to provide a timeframe.
"We hope you can get back to enjoying your Saturday plans once your power is back on," the company said on Facebook.
The power would be restored gradually through the affected areas.
Transpower said while the power supply was fixed, restoring it to each area safely would take time.
"We know it's never easy to be without power, and especially at such a busy time of the year leading up to Christmas," it said in a statement.
"Lightning strikes are a regular hazard for our power system in New Zealand. While our system is pretty robust, from time to time a lightning strike does take out a circuit - it's impossible to protect against this."
The outage is affecting much of the central North Island, including all Firstlight Network customers in Gisborne and Wairoa.
Line provider Unison said the outage had affected at least 50,000 people in Napier and Hastings.
"It's quite a major outage. We are still trying to confirm how many people have been affected," a Firstlight spokesperson said.
Hawke's Bay Regional Council said they have sent a generator to the Haumoana pump station, to keep it working during the power cut.
"Our team is on the ground monitoring river and stream levels across Hawke's Bay and is ready to deploy additional generators and/or portable pumps to other pump stations if required," a council spokersperson said.
RNZ listeners have been texting in about the power outage.
"What's happening with the power? Out in Clive, Napier ... perhaps even further," one said.
"No power as far north as Gisborne," another person reported.
Others on social media helped with brainstorming how to heat milk for babies to make it safe, during the power outages.
