Comparing Power, Gas, and Internet Providers in NZ

After your mortgage, utilities represent one of the larger ongoing costs of homeownership. Power, gas, internet, and water (in some areas) add up quickly, and the difference between the best and worst value providers can be significant. Yet many homeowners stick with whoever they signed up with when they moved in, never questioning whether there is a better option.

This guide explains how to navigate New Zealand's utility market, compare providers effectively, and make informed switching decisions.

Understanding the Electricity Market

New Zealand has multiple retail electricity providers, although availability varies by address. Retailers compete on pricing, service and plan features; changing retailer does not change the local lines network supplying the property.

• Energy charges: The cost per kilowatt-hour (kWh) of electricity you use
• Daily fixed charge: A daily fee that may apply regardless of usage; check the current plan and tariff
• Network charges: Fees paid to the lines company (passed through by your retailer)
• Metering charges: Costs for reading and maintaining your meter

Retailers structure their pricing differently. Some have low daily charges but higher per-unit rates; others charge more per day but less per unit. The best option depends on your household's usage patterns.

Using Powerswitch to Compare

Powerswitch is a free, independent comparison service backed by Consumer NZ. It can compare electricity and gas plans using an address or bill. The Electricity Authority separately runs Billy to help consumers compare electricity and gas plans against how they use energy.

Comparison tools provide estimates based on the information supplied and the plans they cover. Check the estimate, inclusions, discounts, fees, contract term and retailer terms against the written offer before switching.

• Before your current contract expires
• Annually, even if you are on an open-term plan
• After significant lifestyle changes (working from home, new baby, etc.)
• When you see promotional offers and want to verify they are genuinely good value

Fixed-Term vs Open-Term Contracts

Electricity retailers may offer fixed-term and open-term arrangements. Terms, pricing, renewal rules and exit rights vary, so compare the current contract rather than assuming a standard duration or level of flexibility:

A fixed-term offer may include incentives or particular pricing, and may also include early termination fees or renewal rules. Consumer Protection recommends checking the contract length, break fee, pricing plan and payment options before signing.

An open-term arrangement may provide more switching flexibility, but pricing, notice requirements and other terms still depend on the contract. Compare the total offer rather than assuming incentives or price-change rules.

Compare fixed-term and open-term options against your budget, expected length of stay, need for flexibility, renewal rules and possible exit fees.

Natural Gas Considerations

If your home uses natural gas for heating, hot water, or cooking, you will need a gas retailer in addition to electricity. Some retailers offer bundled power and gas with multi-utility discounts; others specialise in one or the other.

Gas retailer availability and pricing vary by address and plan. If work on heating, hot water or cooking appliances is already being considered, compare the installation and running costs, service availability and suitability of gas and electric options for the property.

For gas and electricity, Consumer Protection points to the Electricity Authority's Billy comparison tool; Consumer NZ-backed Powerswitch also compares energy plans. Check tool coverage and compare estimated total cost rather than one advertised rate.

Choosing an Internet Provider

Internet plans use several technologies, and availability and performance vary by address. Consumer Protection recommends using provider address checks or the National Broadband Map before choosing:

• Fibre: Generally offers faster download and upload speeds, but is not available at every address
• VDSL: Copper-based service whose available speed depends on the property and network
• Fixed wireless: Wireless connection to a nearby tower; speeds vary by location and congestion
• 4G/5G home broadband: Mobile-network options whose performance depends on coverage, capacity and provider terms
• Satellite: Availability, performance, equipment and pricing depend on the provider and location

The right choice depends on your location, usage needs, and budget. Compare advertised and expected performance against the number of users, applications, address and provider coverage; avoid relying on a universal minimum speed.

What Speed Do You Actually Need?

Internet providers market their fastest plans aggressively, but many households pay for speeds they cannot actually use. Consider your actual usage:

• Basic browsing and email: Needs vary with the number of simultaneous users and service quality
• Streaming video: Check the streaming service requirements and simultaneous household use
• High-resolution streaming: Check service requirements, simultaneous use and expected provider performance
• Working from home: Consider video calls, uploads, reliability and simultaneous household use
• Gaming and large downloads: Higher speeds reduce wait times but are not essential for gameplay
• Multiple heavy users: Compare plans using expected simultaneous use and address-specific performance

There is no single speed range that suits every household. Consumer Protection recommends considering what you use the internet for, what you can afford, coverage and the services available at your address.

Bundling: Worth It or Not?

Some providers offer bundles combining electricity, gas, broadband, and even mobile services. Bundling can simplify billing and sometimes offers genuine savings through multi-service discounts. However, bundling can also lock you into mediocre services for the sake of convenience.

Before bundling, compare the total cost against choosing the best individual provider for each service. Sometimes the bundle discount does not compensate for higher base prices on individual services. Use comparison tools for each utility independently, then check whether bundles genuinely beat the unbundled total.

Making the Switch

Consumer Protection says switching electricity or gas retailer is generally easy and free, but existing contract terms or break fees may still apply. Confirm transfer steps, meter information, effective date and final billing with the retailers involved.

For internet, timing and installation depend on the address, providers and whether the technology changes. Confirm activation, equipment, installation, overlap or outage risk, and cancellation timing before ending the existing service.

• Check for early termination fees on existing contracts
• Note any loyalty credits or rewards you might forfeit
• Read the new contract terms carefully, including rate increase clauses
• Keep records of sign-up incentives promised
• Set a reminder to review again when any fixed term expires

Building Good Utility Habits

Beyond choosing a provider, reducing avoidable energy use can lower bills. EECA recommends practical steps such as efficient appliance use, draught proofing and heating only the rooms being used; actual savings depend on the home, equipment, behaviour and tariff. Understanding internet usage also helps when comparing plan capacity.

Review utility plans when a fixed term ends, pricing changes or household needs change. Compare the complete current offer, including service, coverage, discounts, fees and contract conditions, and switch only if the written comparison supports it.
