The average annual power bill has continued to fall, reaching a new 11-year low in real terms according to the latest
data released by MBIE, Electricity Retailers’ Association Chief Executive Cameron Burrows says.
The average annual power bill in the year to March 2020 was $2067—down $156 in the past five years after inflation, and
the lowest it’s been since 2009.
“Strong competition between power companies is helping keep prices down. There are now over 30 power companies meaning
we’ve got the most competitive market ever, and everyone’s working hard to keep customers and gain new ones. That’s a
great incentive to keep prices low.
“Improvements to housing quality and energy efficient heaters have also led to savings in power consumption over the
past 10 years, helping keep bills down—though that trend has recently reversed. Consumption is higher than it was in
2017 or 2018, but the average bill has continued to fall, meaning households are using more electricity compared to
three years ago but paying $60 less in real terms.
“New Zealand has the 10th cheapest electricity in the OECD—and it comes to Kiwis in a way that’s highly renewable, very
reliable, and with a great amount of choice.
“Increasingly we’re seeing price isn’t the only thing that matters—consumers care about non-price factors like plans
that bundle in other utilities, offer smoothed monthly payments to avoid winter bill peaks, and different billing
schedules to suit a customer’s circumstances.
“We encourage all Kiwis to have a chat to their power company and check they’re getting the most out of their plan, or
to compare their options on Powerswitch (powerswitch.org.nz). That’s something we should all be doing at least once a year.”Annual average expenditure and consumption of electricity per householdverage annual residential expenditure (real)Average annual consumption per household (kWh)2003$1,60774692004$1,75977642005$1,97781512006$1,88776302007$2,01978402008$1,97675262009$2,03376442010$2,14379032011$2,14276232012$2,18276092013$2,20375072014$2,21273802015$2,22372792016$2,17272612017$2,13070482018$2,10670192019$2,11671412020$2,0677099
