Analysis from Consumer NZ and Powerswitch has found major differences in electricity pricing depending on where you live, with those in lower income areas being
hit the hardest.
Those who live in Kerikeri, for example, are charged 40% more on average than a similar household in Auckland (where
incomes are approximately 25% greater). Prices in Masterton are 15% higher than they are just over the hill in
Wellington.The price in Westport, which has lower-than-average incomes,is close to 40% higher than in Christchurch,
which on average has higher incomes.
“It’s a tragedy that those in lower income areas are having to pay more for what we regard as an essential service. The
price disparity between lower and higher income areas is contributing to inequality and energy hardship," Powerswitch
manager Paul Fuge said.
Regions that have higher prices tend to have lower population density, are further away from power stations, or have few
large commercial electricity users. With a typical power bill, about 40% of the payment is electricity lines charges –
which is the cost of the infrastructure required to get electricity from the power station to your home – so there are
fewer households and businesses to spread these costs over. Unfortunately, many of the consumers in these areas also
have lower-than-average incomes.
Consumer NZ analysis has found that regions with high prices are also areas where large numbers of consumers have either
never changed electricity providers or have done so seldomly. These regions are more likely to be dominated by a single
electricity retailer.
“Competition in electricity helps keep a lid on power prices. However, recently we've seen some of the smaller more
competitive retailers leave Powerswitch. High wholesale electricity prices have resulted in them pausing taking on new
customers,” Fuge said.
Analysis ofabout 7000Powerswitchresults pages generated overwinterin 2021indicated that median savings in switching to
the cheapest pricing plan were$310.
