Sharp electricity price rises spark panic among Canterbury households

Sunday, 7 June 2026

Driftwood is supplementing the Rose family’s power bill, and still it was $400 last month, almost a $100 increase on the same time last year.

Aurelia Rose and her husband Nick take their Mitsubishi Outlander to their local beach in Westport once a week, filling the boot with fuel for their wetback fireplace.

They usually time it during fine weather. “After a storm is probably best because a lot of stuff washes up,” she said.

The couple moved from Linwood in Christchurch to the West Coast two years ago for a safer, more affordable life with their two young children, but recently the power bill had been creeping up.

Last month their Powershop bill was $399.51, compared to $314.98 the same time last year.

“It’s quite a leap.”

She said they had not changed any habits that would prompt an increase in their power bill and spent more time as a family in the living room. “If anything we’ve cut back on what we’re doing.”

Loyal to Powershop, she was not considering shifting companies because it was lenient on bill payments, unlike other suppliers they had been with that threatened to cut the power if payments were late.

“They’re really good, if you can’t afford your bill, they let you pay it off,” she said.

Households are regularly being told to shop around to find a better deal, but it’s not that simple.

Consumer NZ says there are more than 15,000 electricity and gas plans nationally, while some of the choices available to households depend on address, meter type, retailer coverage and plan structure.

Its research showed nearly 40% of New Zealanders thought all energy providers charged about the same, but that was not true, with users of its Powerswitch comparison service saving an average of $450 a year.

But working out whether a household is on the right plan is difficult when the bill itself is made up of several layers.

A power bill includes electricity generation, Transpower’s national grid charges, the local lines network, retailer costs, metering, levies and GST. Some charges are regulated, while others are passed through from one company to another.

That makes it hard for households to see who is responsible when their latest bill is much higher than the same time as last year.

Christchurch resident Emma Cameron was concerned when she saw her $418.54 Powershop bill for May.

“That power bill was the first one that I was like, ‘what, how?’ It’s freaking me out a little bit.”

Powershop is a subsidiary of Meridian, and has an app that encourages users to buy monthly packs and discounted deals to allow them to pay for power months in advance.

Cameron said it was time to start looking at other power companies, especially as her parents had switched from Powershop in the last month after being with it for more than a decade.

When her mum uploaded their most recent power bill to Billy.govt.nz, an Electricity Authority comparison website, she found being with Mercury could have saved them $54 for that same billing period.

Motivated to leave Powershop due to price increases and an updated app that made it harder to break down power usage, Cameron’s parents switched to a no-frills Mercury plan that was cheaper in the long run than signing to another plan that included a $300 joining fee credit.

Ashlin Taylor in Christchurch has also made the move from Powershop.

Taylor said most of the time he and his partner shopped around to ensure they were getting the best deal.

In May last year their Powershop bill was $380. Their April bill this year was close to $400, despite the couple “being conservative” and spending less time at home.

“It’s quite a big one for two adults in a flat, and we’re not at home from 9am to 5pm every day.”

When questioned by Taylor, the company wouldn’t offer him a better deal, leading to him cancelling their plan and switching to Mercury.

Mercury had an attractive reward for new customers including six months of discounted power, a discount for combined power and internet, and free power days.

He said it often paid to switch power companies as they were keen to get new households on board - there was “no value in staying loyal to a company”.

Stats NZ figures show residential electricity prices rose 12.5% in the year to the March 2026 quarter.

But electricity prices are only part of the bill. The cost chain starts with Transpower, which recovers the cost of the national grid from lines companies such as Orion, which services Christchurch.

Orion increased its average delivery prices by 14.5% from April 1. It then adds its own costs before retailers pass those charges on to households, alongside the cost of buying electricity, metering, levies, GST and their own operating costs and margins.

Add in other factors, such as a plan change, the loss of a discount, higher fixed daily charges, or more power use during a cold snap, and a household’s bill can rise faster than the headline electricity price measure.

That’s why a bill can feel like it is always going up, even when the source of the increase is hard to pin down.

Consumer NZ says price increases and the lack of clarity is occurring when trust in electricity retailers is falling.

Last week, it refused to award its annual People’s Choice accolade to any energy retailer, saying no company met its threshold for both high customer satisfaction and strong customer care.
