Our goals and progress

Under the Energy Efficiency and Conservation Act, EECA is charged with promoting energy efficiency, energy conservation, and renewable energy. We are mobilising New Zealander's to be world leaders in clean and clever energy use.

Corporate documents

EECA publishes a range of corporate and strategic documents including Annual Reports, Statement of Performance Expectations and Statements of Intent.

EECA’s goal is for more New Zealanders to have warm, dry and more energy efficient homes. Since 2008, EECA has administered the Warm Up New Zealand programmes to insulate homes. To date, more than 292,000 homes have been insulated (June 2016). EECA estimates that there are around 600,000 houses with inadequate insulation still remaining in New Zealand.

EECA’s largest programme by far, the Warm Up New Zealand: Heat Smart insulation scheme, had a substantial piece of cost benefit analysis conducted.

The RightLight information campaign has been running since 2009 and encourages households to choose more energy efficient lighting, such as CFLs (compact fluorescent lamps) or LEDs.

In the period April 2013-March 2014 nearly one in four bulbs sold in supermarkets were energy efficient – saving households money and reducing energy waste.



Businesses in New Zealand use 50% of overall energy, and produce more than 40% of New Zealand’s energy-related carbon emissions.

EECA works to improve business energy use by:

  • Improving energy awareness
  • Improving industrial and commercial energy efficiency
  • Improving the efficiency of business products
  • Encouraging greater use of renewable energy resources

A major focus for EECA are New Zealand's largest energy-using organisations, which use approximately 70% of all the energy used in the business sector. A number of these have now signed long term energy management partnerships with EECA, including AFFCO, Auckland International Airport, Downer, Goodman Fielder, Fulton Hogan, Orora Packaging, Talleys, Fonterra, the New Zealand Aluminium Smelter, and ANZCO.


Transport accounts for almost 40% of New Zealand’s energy use. With almost 100% of vehicles fossil-fuelled, the sector is responsible for more than 45% of New Zealand’s energy-related carbon emissions (about 20% of New Zealand’s total).

EECA works to improve transport energy use by:

  • Promoting uptake of electric vehicles
  • Providing vehicle fuel economy information, to inform vehicle purchase decisions
  • Encouraging motorists to regularly check tyre pressure
  • Encouraging the use of biofuel

Products – standards and labelling

EECA’s products programme provides information about the efficiency of products to consumers and regulates some products.

Twenty product categories are currently regulated for energy efficiency, including household appliances (such as refrigerators and televisions), and commercial and industrial equipment (such as commercial lighting and electric motors).

Products sold subject to regulation and under the ENERGY STAR programme have saved New Zealanders 18 PJ of energy worth $450 million in total since the programme began. [data correct as at 31 March 2014].

The E3 and ENERGY STAR programmes have proven highly cost-effective, delivering these savings at a total cost to EECA of $21 million since the programme began.

The costs and benefits of regulating each product class – such as fridges, and heat pumps – are established in detailed regulatory impact statements.

Electricity efficiency

EECA’s electricity efficiency work is funded through the Electricity Levy, a levy of all electricity users, which also funds the Electricity Authority (EA).

EECA consults on its use of the levy each year, and at the same time publishes an annual report on its use of the levy funding for the previous year.

Energy Link study 2015

This independent report models the future impact of EECA’s electricity efficiency programmes on wholesale electricity prices. A new approach to the analysis found the modelled carbon mitigation impact of EECA programmes from 2016/17 onwards was significantly higher (180,000 tonnes p.a.) than EECA’s historical estimates (56,00 tonnes p.a.).

New Zealand Electric Energy Efficiency Potential Study

Opportunities for electricity savings in New Zealand are identified through a number of means. This study by KEMA in 2007 looked at the electric energy efficiency potential in New Zealand's residential, commercial and industrial sectors.

Working with partners

EECA has a long track record of working constructively with a range of partners in the public and private sector.

  • Insulation retrofits delivered through Warm Up New Zealand are part-funded by charities, trusts, DHBs, and service providers. In 2013/14 this funding was worth $28 million.
  • EECA develops energy efficiency regulation through its participation in the trans-Tasman Equipment Energy Efficiency (E3) Programme. By working with Australia and basing regulation on international standards, we minimise cost to the Government and industry and raise the energy efficiency of products supplied to the New Zealand market.
  • EECA works with the New Zealand Green Building Council to deliver the NABERSNZ rating scheme for commercial buildings.
  • EECA works with the Ministry of Transport and the New Zealand Transport Agency on low emissions transport options including the Electric Vehicle programme.  EECA is responsible for the EV information campaign.
