Meridian Energy has confirmed it is proposing to cut retail jobs across its Powershop and Meridian brands.
The energy company says the proposed restructure would see a number of roles disestablished, along with new ones being introduced.
It would reduce the number of retail workers at the company by eight percent.
Chief customer officer Lisa Hannifin said the company needed to adapt if it wanted to continue to succeed.
"Customers expect more and have an increasing range of options for how and when they use energy. We need to relentlessly find ways to deliver value back to customers, saving them time and money. We need to understand customer needs and quickly turn ideas and concepts into products and experiences that customers love.
"All of this requires a reset of our retail business and that's what this proposal is about.
"It's a big change for our people, but I think it's also an exciting one. It's a different way of working, but with that comes a lot of new opportunities. We're asking our people to get behind this change, but we're also supporting them through what I recognise is a period of uncertainty, which can be difficult."
Employees can provide feedback on the proposal before 8 October, with a final decision expected to be announced two weeks later.
In August, it was reported Meridian Energy made $429 million profit - over four times that of the year prior.
