New Zealand electricity: What you need to know

New Zealand’s electricity market has evolved significantly over the years, with consumers now having a variety of options and a range of information at their disposal when choosing a retail provider. Canstar Blue has produced a one-stop guide to the NZ energy market to help you find a better deal.

About the New Zealand energy market

In understanding the current state of the New Zealand electricity market, it is worthwhile casting a brief look back over its recent history. Tracking the market’s evolution, the 1980s had seen momentum build for change, with a number of initiatives undertaken by government at the time, looking into the Crown’s role in the electricity sector.

As described by the Electricity Authority, an Electricity Task Force in 1989 had “recommended separation of the ownership of generation and transmission assets and the development of a light-handed regulatory regime”.

The 1990s subsequently saw industry development of three self-regulating arrangements, governing operation of the market, with the Electricity Authority noting that the rules in the agreements are the foundation of today’s code, the Electricity Industry Participation Code.

The code itself “is a set of rules that govern nearly every aspect of New Zealand’s electricity industry”, which includes:

  • Generation
  • Transmission
  • System operation
  • Security of supply
  • Market arrangements
  • Metering
  • Distribution
  • Retail

The precursor to the Electricity Authority, the Electricity Commission, was established in 2003 to regulate the market, with the Electricity Authority itself, an independent Crown entity providing regulatory oversight of the sector, established in 2010.

What is the role of the Electricity Authority?

The Electricity Authority states that its “work is focused on addressing key questions that affect the long-term benefit of consumers”:

  • Are prices reasonable?
  • Will the lights stay on?
  • Do consumers have choices?
  • Is innovation occurring?

In carrying out its functions, it outlines its objective as “to promote competition in, reliable supply by, and the efficient operation of, the electricity industry in New Zealand for the long-term benefit of consumers”.

Working to ensure healthy competition, reliable supply and efficient market operation, and looking to the future health of the market, the Electricity Authority seeks to ensure that:

  • Consumers have a variety of suppliers and products to choose from within a highly innovative and competitive retail sector.
  • The electricity market efficiently meets the country’s future electricity needs – the incentives to invest in generation and manage electricity consumption reliably deal with dry spells and other supply shortages.
  • Prices for electricity are consistent with workable competition at all locations and all times.
  • Its engagement and communication with all stakeholders is clear and consistent, enabling greater understanding of the market and its development.
  • The electricity market has a high level of credibility – both nationally and internationally – giving stakeholders confidence.
  • Market arrangements support innovation and investment.

Diversified energy company Genesis, New Zealand’s largest electricity and gas retailer, supplies energy through its retail brands, Genesis Energy and Energy Online.

Electricity plans: What to look for

Across the above and other electricity retailers operating in the New Zealand market, a variety of plans, catering to various consumer requirements, are on offer.

In selecting a plan, consumers should consider their individual household requirements, taking into account when the bulk of their electricity usage occurs. Factors that consumers may take into account when selecting a plan include:

  • Fixed and variable rate charges

  • The fixed charge is a daily rate charge, while the variable charge is determined by how much power is used.
  • Time-of-use

What different rates are available for different times of use? For instance, customers using the majority of their electricity at night should search for plans catering to this particular type of usage.

  • Fixed-term or flexible contract

Are you willing to lock in to a long-term plan, or are you looking for greater flexibility?

  • Discounts

Are pay-on-time and direct debit, or other types of discounts, offered?

  • Solar requirements

What sort of solar options are on offer?

  • Support

What sort of support services are retailers offering? For instance, online and app account support.

  • Additional perks

What other perks and discounts are retailers offering?
