Your Credit Score: What It Is, Why It Matters and How to Check It

If you've ever applied for a loan, a phone plan or even a rental property, chances are someone has checked your credit score at some point along the way. It can influence many of your everyday financial decisions and yet most people aren't really sure what it is or how it works. So here's the plain-English version, to shed some light on the subject.

Written by the Armstrong's Finance team. Armstrong's Finance is a New Zealand registered finance broker and Financial Advice Provider, licensed and operating under the Financial Markets Conduct Act 2013, which means we are required by law to act in your best interests. This guide draws on the Credit Reporting Privacy Code 2020 and guidance from Consumer Protection (NZ).

What is a credit score?

Your credit score is a credit rating, usually expressed as a number, that gives lenders a quick snapshot of how you've handled borrowing and repayments in the past. The higher your score, the lower the risk you appear to a lender, which can improve your chances of approval, often at a more competitive rate. A lower score doesn't rule you out, but it can mean fewer options or higher interest rates.

In New Zealand, your score is calculated by one of three credit bureaus: Centrix, Equifax and Experian. Each uses a slightly different scale, but they're all measuring the same thing: how reliably you've met your financial commitments.

What goes into your credit score?

Your score is based on the information in your credit report, which is a record of your financial history. The main things that shape it are: whether you pay your bills and loans on time, any defaults in your name, how much credit you already have, and how often you've recently applied for credit. One thing to note, and it surprises a lot of people, is that your income and savings don't appear on your report and these don't affect your score.

What is a good credit score in NZ?

There's no single national number, because each bureau uses its own scale, so a “good” score depends on which one is reporting. As a rough guide, many consumer scores run from around 0 to 1,000 and the higher you sit, the stronger you look to a lender. Rather than quoting an exact range that varies between bureaus, it helps to think in broad categories, from below average through to excellent. In practice, lenders use both the score and the detail behind it, the number gives them a quick read, and your repayment history fills in the rest.

Why do credit scores matter?

When you apply for finance, most lenders run a credit check as part of their assessment. A strong score can often open the door to better rates and a smoother approval. 

If your score isn't where you'd like it to be, there are still options, and it helps to have someone who knows where to look. 

At Armstrong's Finance we look at your full picture, not just the number, and work across a panel of lenders to find an option that could suit you best. Whether you're after a personal loan or car finance, we can help you find the right fit.

How do you check your credit score in New Zealand?

You're entitled to a free copy of your credit report from each of the three bureaus. You can request it directly from any of them:

• Centrix – centrix.co.nz
• Equifax – equifax.co.nz
• Experian – experian.co.nz

Most requests are handled online and come back quickly. Checking your own report won't affect your score, so you can look as often as you like. If you're thinking about finance and aren't sure where to start, your broker can walk you through what to check and how to get ready to apply.

How to look after your credit score

The single most important habit is paying your bills on time; power, phone and loan repayments included. Automatic payments make that easy, so nothing slips through by accident. Beyond that, keeping an eye on how much credit you're using and not applying for too much at once both help.

And if you've had a few bumps along the way, it doesn't mean you're stuck. Scores recover over time as your recent history builds up. If your credit history isn't perfect, our guide to secured and unsecured loans is worth a read, since a secured loan can sometimes be easier to arrange.

Frequently asked questions

How do I check my credit score for free in NZ?

Go directly to any of the three bureaus, Centrix, Equifax or Experian, and request your report. There's no cost for the standard service, and each can hold slightly different information, so it's worth checking more than one.

Does checking my own credit score lower it?

No. Checking your own report has no effect on your score. Only a check run by a lender or other third party, with your consent, shows up as an enquiry on your file.

How long does a default stay on my credit report?

Five years from the date it's listed, even once you've paid the debt off. Defaults below the minimum threshold, currently $125, generally can't be recorded. The five-year limit is set by the Credit Reporting Privacy Code.

Can I get a loan with a low credit score?

A lower score tends to mean fewer lenders and a higher rate rather than an automatic “no” and some lenders weigh your current income and stability more heavily than past blips. Because we work with a range of lenders, we can point you toward the ones most likely to say yes.

A final word

Your credit score is worth understanding, but it's only ever part of the story. A number on its own doesn't capture your whole financial situation, which is exactly why we look beyond it. Where some lenders see a score, we see the person behind it, and that's often what makes the difference to getting a yes.
