If you’re preparing to apply for a mortgage or simply reviewing your financial position before taking the next step, it’s worth understanding how credit scores work in New Zealand. Knowing what lenders are actually looking at when they assess risk can help you go into the process with a clearer picture of where you stand.
Take a borrower who had always paid their bills on time and assumed their credit score would reflect that. When they finally checked it before applying, they discovered an old utility default they hadn’t known about. Even one old default can change how lenders are likely to assess the application. A small issue, but one that could still influence lending decisions.
What Is a Credit Score?
Your credit score is a numerical rating linked to your financial history and credit behaviour. In New Zealand, lenders and credit providers may use it as one of several indicators when reviewing an application.
A credit score can influence:
which lending options may be available
how a lender views financial conduct
whether additional information may be requested
Credit scores are only one part of the overall picture. Payment history, current commitments, and broader financial conduct can also influence how an application is viewed over time. A lower score does not automatically prevent someone from borrowing, but it may affect the lending options available depending on the overall situation.
How Is My Credit Score Determined?
Your credit score is calculated using information from your credit history and financial conduct over time. Different credit reporting agencies use different scoring models, which means your score can vary slightly between providers.
Factors that may influence your score include:
repayment history
defaults or missed payments
utility bill payment history
how often you apply for credit
the types of lending you use
how frequently your details change, such as your address
How and Where Can I Get a Copy of My Credit Report?
There are three main companies in New Zealand that track your credit information. These are:
Equifax
Centrix and
illion
Because each provider uses its own reporting systems and scoring methods, your credit score may vary slightly between them. You can request a free copy of your credit report from each provider, although charges may apply for urgent requests.
Once you receive your report, it’s important to review it carefully for errors or unfamiliar activity, as incorrect information can affect your credit profile.
What Is a Good Credit Score?
Credit scores are between 0 and 1,000.
Zero is considered the lowest possible score
1,000 the best at illion and Centrix, while Equifax can go up to 1200.
A score of 500 and above is generally considered “good”.
Instead of focusing only on the number, lenders consider overall credit conduct and financial stability.
How Long Does Credit Information Stay on Your Report?
This varies between agencies since they retain different types of information for different periods of time. Some information may remain for several years, depending on the type of listing and the agency involved. This means over time, positive financial conduct can gradually strengthen your profile as older negative events expire.
Who Has Access To My Credit Report?
Providers can ask for your permission to access your credit report. This is common practice when you:
Apply for a home loan or credit
Sign up with a utilities company (electricity, internet etc)
Apply for a job (especially if you have financial responsibilities)
Apply to rent a property
Your credit report can be provided without your permission to certain government agencies, debt collectors and in court proceedings against you.
How Do I Improve My Credit Rating?
Depending on the reason for your low score, here are some recommendations on how to improve your credit rating:
Firstly, check your credit report is correct. If it includes incorrect information, contact the credit report companies to get it fixed. If there are loans and credit checks you didn’t approve, you may be a victim of fraud. If you notice unfamiliar loans or credit checks, it may be worth investigating further by reporting it to the authorities, and they will give you more information on what to do in that case.
Start building a good payment history by consistently paying your bills on time.
Pay down current debts as much as possible.
Avoid taking on unnecessary or additional debt.
Reduce the number of credit cards you have, as well as your credit card limits.
Your credit report is made up of data from the previous four years only. Therefore, over time you can build up a history of good financial behaviours while the history of negative ones drops off the record.
What If My Credit History Has Already Led To a Decline?
Credit history is only one part of the overall picture. Lenders may also consider broader financial conduct, repayment history, and the overall application when reviewing lending options.
A lower credit score does not automatically prevent you from getting a mortgage, but it can affect how lenders assess your application and which lending options may be available.
If credit history has already affected a lending application, it may help to first understand some of the reasons mortgage applications are declined and how lenders assess risk.
In some situations, borrowers may also explore non bank lending options where applications fall outside standard bank criteria.
