To resolve an issue as quickly and easily as possible, you need to:

  1. Verify you have an issue.
  2. Decide the outcome you want.
  3. Gather your evidence.
  4. Contact the retailer or service provider.
  5. Work together to resolve the problem.

These steps are in our visual guide and written out in more detail below.

1. Verify you have an issue

Make sure you have a valid reason to complain. Consumer law doesn't apply if you caused the damage or lost an item.

If it is a valid complaint, it helps if you:

  • can prove purchase details
  • have been using the product or service as intended

Check you have a case

2. Decide the outcome you want

Think about what it would take to make it right. Do you want:

  • a refund
  • repairs or improvements
  • a replacement.

Be reasonable in what you ask for. Make sure what you're asking for is in proportion to the size of the issue. If you're offered repairs but don't want that, explain why it's not a satisfactory outcome for you.

3. Gather evidence and write a description of the issue

You should write down in detail what the problem is with the item or service. Include details like:

  • a description of the item or service
  • date of purchase
  • date the problem occurred
  • what you've done so far
  • details of any official conversations you've had about it
  • any reference numbers
  • what you would like done about the issue.

Check what your legal rights are. Make a note of which law(s) apply to your problem. You might want to name that law when making the complaint.

Consumer laws

Keeping records

Keep any documents that relate to your complaint and take them with you or include copies when you make your official complaint. Keep things like:

  • sales dockets, receipts, and invoices
  • hire purchase agreements or credit contracts
  • layby agreements
  • guarantees
  • bank statements if the dispute is over a payment or account.

4. Contact the retailer or service provider

Once you've got all your evidence together and know what outcome you want, contact the seller to discuss the issue.

Take your complaint further

Act fast

Tell the service provider or retailer about an issue as soon as you find it. If you wait too long, you might lose the right to a remedy.

5. Before you complain

Check what the company's complaints process is – they might have details on their website, or you could call them to check.

Before you make the complaint, get prepared. It can be good to write things down even if you're complaining over the phone or in person, so you know what you want to say.

Always ask for advice

Check with the retailer that the item you’re purchasing will do the job you need it for. If you then find that it does not work as described, you should seek a remedy based on it not being “fit for purpose”.

6. Complaining by phone or in person

It's worth having an initial discussion before progressing to a formal complaint. Whether you're just discussing the problem or making a formal complaint, always prepare first. Be clear about what the issue is, when it happened and how you would like it resolved.

Tips on how to discuss a problem

  • Talk to the right person. The person you speak to needs to have the ability to resolve the issue, for example, a store manager, business owner or supervisor.
  • Focus on talking about the problem with the product or service, rather than taking issue with a person.
  • Stay calm and reasonable. Explain the problem in detail and provide any evidence you may have.
  • Tell them what outcome you want.
  • Expect questions. A store or service provider may ask you for more details.
  • Ask to speak with someone else if you’re not happy with the way the conversation is going. It’s okay to walk away and come back later, or to follow up in writing.
  • Listen to their response. Ask for time to consider it if you need to.

If you’re not comfortable talking to the store or service provider, take a friend or family member for support.

People who are deaf, hard of hearing, speech-impaired or deafblind can connect with businesses by using the New Zealand Relay Service. A relay assistant can help arrange communication with others over the phone. The service is free.

7. Writing a complaint

Your letter or email should be clear and concise — aim to keep it no longer than a page. It should:

  • include details of the purchase, such as a description of the item or service, purchase date and seller details
  • give a detailed description of the problem and when it occurred
  • be as factual as possible
  • explain what you want done to fix the problem
  • include when you want a reply by
  • include your contact details
  • include copies of your receipts, sales contract, or other proof of purchase — don't send originals.

Example — Wrong phone plan

When Paul signed up for an internet package, the salesperson tried to upsell him on a package with a fixed phone line. Paul said he didn't want it. But when his first bill arrived, he discovered he was being charged for the package with the phone. He rang the company and calmly explained the situation, telling them he wanted the package he had requested. The customer service representative corrected his plan and updated his bill to the correct amount.
