Overview

Settling your Slingshot energy bill

When it comes to paying your power bill, the goal is simple: pick the method that fits your routine, avoid late fees, and keep your account in good standing. Slingshot, like every licensed New Zealand electricity retailer, accepts a handful of standard payment channels — and offers more flexible arrangements if you need help spreading the cost.

Payment methods

How to pay your Slingshot bill

Choose the method that fits your routine. Each option below is a standard channel offered by New Zealand electricity retailers.

Online account / web portal

Available

Sign in to the Slingshot customer portal with your email and password. Pay with debit or credit card, schedule a one-off payment, set up recurring direct debit and download past invoices in PDF.

Sign in to your account

Mobile app

Available

The Slingshot app lets you pay with a saved card or bank account in two taps, view consumption alerts and receive push notifications when a new bill is issued.

Direct debit

Available

Authorise Slingshot to pull each bill directly from your bank account on the due date. Most NZ retailers offer a small prompt-payment discount when you set up direct debit — typically around 1% to 2% of the invoice.

Regular instalments

Available

Ask Slingshot to split your annual estimated usage into fixed weekly, fortnightly or monthly payments. Plans are reviewed every few months so payments can be adjusted up or down to match real consumption.

Internet banking / bank transfer

Available

Pay from your own bank's app using Slingshot's bank account number printed on the bill. Always include your account number or invoice number as the payment reference so the payment is matched to your account.

Phone payment

Available

Call Slingshot on 0800 89 2000 (General Enquiries & Tech Support: Mon–Sat 8am–8pm; Sun/ES/PH 10am–8pm. Collections: Mon–Fri 8:30am–5pm. Sales: Mon–Sat 8am–8pm; Sun & PH 10am–8pm.) and a customer-service agent will take a card payment over the phone or set up a payment plan for you.

Some retailers accept over-the-counter cash or EFTPOS payments at NZ Post PostShops and selected retail partners. Bring your printed bill so the cashier can scan the barcode and match the payment.

Your rights

Is your energy bill overdue? Here's what the law says

Every electricity provider in New Zealand must follow the Electricity Authority's Consumer Care Obligations. These rules set the minimum standards for how overdue bills are handled and they apply to every retailer, including Slingshot.

Before disconnection

If you haven't paid your bill, Slingshot must follow these steps:

  • The retailer must send reminders before disconnecting.
  • First warning: at least 28 days after the bill date.
  • Final notice: at least 44 days after the bill, served 24 hours to 10 days before disconnection.
  • No disconnection at night, before weekends or holidays, or during severe weather.

What this means for you: you have plenty of time to pay or arrange a plan. Disconnection cannot happen suddenly or at unsafe times.

Payment support and hardship

If you're struggling to pay your Slingshot bill:

  • Retailers must offer payment plans or instalments.
  • SmoothPay-style options (weekly, fortnightly, monthly) are common.
  • If you receive a benefit, ask WINZ about the Winter Energy Payment to help cover winter bills.
  • Once agreed, a payment plan cannot be changed without your permission.

What this means for you: if you can't pay the full amount, you can negotiate a plan to spread the cost. You are in control of these arrangements, and the retailer cannot change them without your agreement.

Special protections

Two groups of customers are protected by extra rules:

  • If someone in your home is medically dependent, the retailer cannot disconnect your electricity once that person is registered.
  • Vulnerable customers get extra care and support.

What this means for you: if anyone in your home relies on electricity for health reasons, you are legally protected from disconnection. You may also receive extra flexibility if you're in a vulnerable situation.

What to do if things go wrong

If the retailer doesn't follow the rules, you have recourse:

  • If Slingshot disconnects without following the rules, you can complain to Utilities Disputes Limited.
  • The service is free, independent and binding for retailers.

What this means for you: you have a formal avenue to challenge unfair disconnections or billing issues. Keep records of every notice and communication, it strengthens your case.

Fees

  • Disconnection, reconnection or admin fees are allowed but must be reasonable.
  • Retailers cannot bypass minimum legal protections.

What this means for you: you may be charged fees, but they must reflect real costs. You cannot be penalised with unfair or excessive charges.

Common questions

Paying your Slingshot bill — frequently asked questions

Most New Zealand electricity bills are issued monthly and are due roughly 14 to 20 days after the invoice date. The exact due date is printed on the top right of every Slingshot invoice. Direct-debit customers have the amount pulled on the due date automatically.

Many NZ retailers offer a small discount (typically 1% to 2%) when you pay by the due date or set up direct debit. Check the fine print on your current plan or the offer card on the Slingshot plans page for the exact figure.

Under the Electricity Authority's Consumer Care Obligations, Slingshot must contact you before any disconnection: a first reminder at least 28 days after the invoice and a final notice at least 44 days after it. Call the retailer as soon as you know you'll be late and ask for a payment plan or hardship arrangement before fees are added.

Only after the legally required notices have been served, and never at night, just before a weekend, on a public holiday or during severe weather. If somebody in the home is medically dependent on electricity and registered as such with the retailer, disconnection is not allowed.

Yes — retailers may charge a late-payment fee, a disconnection fee and a reconnection fee, but each charge must be reasonable and reflect actual cost. If you believe a fee is excessive you can complain to Utilities Disputes Limited, the free dispute-resolution service for the sector.
