Electrifying Aotearoa: The consumer perspective

Publication date: April 2024

Overview

Energy is a vital part of our lives at home, keeping us warm and powering everything from our appliances to hot water.

New Zealand is at a point where household electrification presents an opportunity to reduce energy use, emissions and costs.

EECA set out to understand where New Zealand homeowners are at, and what current motivators and barriers are. 

The report, delivered by TRA, is focussed on owner-occupiers, and considers the most efficient electric technologies currently available on the market.

Research objectives

The objective of this consumer survey was to:

  • Determine the current stock of appliances/systems in New Zealand households that have the potential to be electrified in a smart way.
  • Assess awareness and consideration of smart electrification options.
  • Assess triggers and timeframes for change.
  • Assess high level motivations and barriers to change.
  • Understand general awareness levels of smart/renewable energy.

Energy uses and technologies explored:

  • Cooking/induction cooktops
  • Heating/heat pumps
  • Hot water/hot water heat pumps
  • Solar and solar batteries
  • EVs and smart chargers

Key findings

New Zealand has an ageing stock of household appliances in owner-occupied houses. At least one-third of non-green appliances are over 10 years old, and over half are at least 6 years old.

Age of appliances in owner-occupied homes. .

Around three quarters of owner-occupier households have reported they are unlikely to switch to greener, electric investment appliances until they reach end-of-life.

Triggers for replacing/changing an appliance..

New Zealand homeowners reported a mix of fuel sources in their homes. Current ownership of different electric options has been found to vary significantly.

Uptake of efficient electric appliances in New Zealand owner-occupier households.

It is not a given that New Zealanders associate electricity with cleaner energy. One-third of homeowners (33%) do not identify electricity as the cleanest energy source out of electricity, gas, coal and oil.

Which energy source do homeowners think produces the lowest emissions?.

While between 80%-85% of the country’s electricity supply does come from renewable sources, only one-quarter (27%) of homeowners correctly estimated the country’s supply to be this high. 

How much of New Zealand's annual electricity generation do you estimate is renewable?.

Next steps

This consumer research will inform our residential electrification work programme.

In the immediate term we will use the insights to bolster the information we provide to owner occupiers, to help with informed decision making at a natural point of replacement.
