Auckland lines company Vector has taken the extraordinary step of telling people to stop using its phone app, because it doesn't work.
It's still desperately trying to restore power to over 25,000 properties after Tuesday night's huge storm, and more bad weather on Thursday night could make that job even trickier.

That's bad news for Devon Roke, who is almost six years-old and struggles with cerebral palsy and lung damage.
When the power went out at his house on Tuesday, he had to spend the night without the machine which helps him breathe.
"He definitely sounded more congested in the morning, than if he'd been wearing the machine overnight," his mother Tracey Roke told Newshub.
Now his family has moved into a motel, and it's costing them $200 a night. Like many, Ms Roke is frustrated with Vector.
"When it first went off, the update said 6pm that night," she said.
"We could tell from the damage it wasn't going to be. So it would have been useful if it said two days."
Vector now admits it needs to be more realistic about how long it will take to restore power.
"We appreciate that's very frustrating for people, so we apologise for that," said Vector's head of networks, Minoru Frederiksens.
But don't check its app for any updates; Vector now says it's overloaded and inaccurate, and there's no word on when it will be fixed.
"We've been a bit caught out - it's a massive storm, nothing like we've seen since the app's been in place," Mr Frederiksens said.
But Vector did know its app wasn't coping back in January, when Auckland was hit with a storm from the north-east.
The app still hasn't been upgraded - and it's promising a full review once power's back on.
Frustration is starting to bite for many of the 25,286 homes still without power.
"The app hasn't really been updating - then I got on the phone and sat on hold for a few hours then got sick of that," one angry resident said.
"It's been pretty slack really."
The power cuts are random and sporadic around the super city.
For example, on one street one half has power, while their neighbours on the other half have been told they'll have to go three days without it.
More bad weather's predicted on Thursday night, but takeaway stores won't be moaning. Those with power have been doing a roaring trade.
"We had a great night last night, nice and cosy in here, wood fire was cranking and a lot of people coming in telling me their hard-luck stories," said pizza maker Scott Limbrick.
If you're without a flushing toilet because there's no power for the water pump, the Auckland Council says it'll provide a portaloo.
