How to Switch Power Providers in New Zealand

Switching electricity providers in New Zealand is simpler than you might think. With over 40 retailers competing for your business, you could save hundreds of dollars a year just by making a switch. This guide walks you through the entire process, from understanding your current plan to completing the transfer.

Whether you're looking for a better price, greener energy, or more reliable service, the steps are the same. Let’s get started.

Why switch power providers?

New Zealand’s electricity market is deregulated, meaning you’re free to choose your retailer. Many households never switch, missing out on potential savings. Here are the main reasons to consider a change:

  • Save money – Competition means providers often offer lower rates or sign-up bonuses.
  • Better customer service – Some companies have 24/7 support or faster response times.
  • Renewable energy options – Choose a provider that sources 100% renewable electricity.
  • Flexible plans – Options like fixed-term, pay-on-time discounts, or low-user tariffs may suit your needs.

Key concepts to understand before you switch

Before diving in, it helps to know a few terms. This will make comparing plans easier.

Daily fixed charge vs variable usage charge

Your bill has two parts: a daily fixed charge (a set amount per day, regardless of usage) and a variable usage charge (per kilowatt-hour, or kWh, you consume). Low-user households often benefit from plans with a lower fixed charge but a higher usage rate. High-user households might prefer the opposite.

Low-user vs standard-user plans

If you use less than 8,000 kWh per year (or 9,000 kWh in some regions), a low-user plan could save you money. Check your annual usage on your last bill. If you’re unsure, most providers’ websites have a calculator.

Contract terms and early exit fees

Some plans lock you in for 1–2 years. If you leave early, you may pay an exit fee (typically $50–$150). Others are month-to-month with no penalties. Always check before signing up.

Prompt payment discounts

Many providers offer a discount (often 10–20%) if you pay your bill on time. If you can’t always pay by the due date, factor this in — may not apply.

Step-by-step guide to switching power providers

Here’s how to switch in seven straightforward steps.

Step 1: Find your current usage and plan details

Grab your latest power bill. Look for:

  • Your annual electricity usage (in kWh)
  • Your current daily fixed charge and variable usage rate
  • Any discounts or special terms you’re on
  • Your ICP number (Installation Control Point) — a unique identifier for your property

This information will help you compare apples with apples.

Step 2: Compare providers and plans

Use a comparison website like Powerswitch (run by the Consumer NZ) or https://www.eeca.govt.nz/ to see available plans in your area. You can also check providers’ own websites.

When comparing, consider:

  • Total estimated annual cost (including fixed and variable charges)
  • Any sign-up credits or bonuses
  • Exit fees and contract length
  • Customer service reviews
  • Whether the provider offers renewable energy

Step 3: Choose a new provider and plan

Once you’ve narrowed down your options, pick the plan that best fits your usage and preferences. If you’re on a low income, check if the provider offers a payment assistance programme.

Step 4: Sign up online or over the phone

Most providers let you sign up in minutes online. You’ll need:

  • Your name and address
  • Your ICP number (found on your current bill)
  • Your bank account details for direct debit (if you choose that option)
  • A preferred start date (usually within 5–10 business days)

The new provider will handle the cancellation with your old one — you don’t need to call anyone.

Step 5: Confirm the switch and check for disruptions

Your new provider will send you a confirmation. They’ll also notify your local lines company (the company that owns the poles and wires) to update billing. Your power supply won’t be interrupted — is purely administrative.

Step 6: Pay your final bill from the old provider

Your old provider will send a final bill, usually within 2–4 weeks of the switch. Pay it by the due date to avoid late fees. If you had a discount plan, make sure you’ve met the terms to keep any savings.

Step 7: Review your new plan after a few months

Once you’ve been with your new provider for a few billing cycles, check your actual costs against what you expected. If you’re not saving as much as planned, consider switching again — there’s no limit on how often you can change.

Tips for a smooth switch

  • Don’t switch during a power outage – Wait until your supply is stable. Switching won’t affect your power, but it’s less stressful to do it when everything’s normal.
  • Check your area’s lines company – Some regions have only one lines company, so distribution charges are the same no matter which retailer you choose. Your savings come from the retailer’s charges.
  • Watch for hidden fees – Some providers charge a fee for paying by credit card or paper billing. Read the terms carefully.
  • Consider bundling – Some providers offer discounts if you also get gas or internet from them. Compare the total cost, not just the power portion.

Common mistakes to avoid

  • Focusing only on the usage rate – A low usage rate might come with a high daily fixed charge. Look at the total annual cost.
  • Ignoring the contract term – If you might move home within a year, a no-contract plan avoids exit fees.
  • Not checking if you’re on a low-user plan – If you use more than 8,000 kWh per year, a low-user plan could cost you more.
  • Forgetting to update your direct debit – Your old provider will stop billing you, but your new one will need your bank details for payment.

Frequently asked questions

Will my power be cut off during the switch?

No. The switch is purely administrative. Your power supply remains the same — only your billing changes.

How long does it take to switch?

Most switches are completed within 5–10 business days. Some providers offer same-day switches if you sign up online.

Can I switch if I’m in debt to my current provider?

Yes, but you’ll still need to pay any outstanding balance. Your new provider won’t take over your debt.

Do I need to tell my landlord if I’m renting?

No, but check your tenancy agreement. Some landlords require you to keep the power in your name. Switching providers is your right as a tenant.
