Doesn't have to be used all at once. I use one hour at a time and schedule the dishwasher, washing machine etc to all run during that time.
Once claimed on your account, the hours stay on your account for a long time - you don't have to use them all before the expiry of this deal.
Here's a 5-hour Power Shout for you
We want to help our customers get through lockdown, so we’re giving you five extra Power Shout hours. You could use your free power to bake, to video call whānau, get on top of some DIY or simply keep warm at home. Do what you want with your free power, when you want – the choice is yours.
