Understand how credit scores work, what’s considered bad, and how it can affect your financial future.
In New Zealand, your credit score plays a key role in your ability to get loans, credit cards, car finance, or even a rental property. But what happens when that score isn’t so great? A bad credit score can limit your financial options and make it more expensive to borrow money. In this guide, we explain what a bad credit score is, how it’s calculated, and how it affects your day-to-day life in NZ.
A credit score is a three-digit number used by lenders and financial institutions to assess your creditworthiness, which essentially indicates how likely you are to repay borrowed money on time. In New Zealand, the score generally ranges from 0 to 1000, depending on the credit reporting agency (Centrix, Equifax, or illion).
While each agency has its own scoring system, here’s a general guide:
Excellent: 800–1000
Good: 700–799
Average: 500–699
Fair / Low: 300–499
Poor / Bad: Below 300
A score under 500 is often considered a bad credit score, and lenders may see you as a high-risk borrower. This can affect your ability to:
Get approved for loans or credit cards.
Qualify for good interest rates.
Lease or rent a home.
Sign up for utilities or mobile contracts without large bonds.
Common reasons include:
Late or missed repayments
Defaults or unpaid debts
Court judgments
Insolvency or bankruptcy
Multiple credit applications in a short period
Identity theft or fraud
Lenders in NZ use your credit score to determine not just whether to approve your loan, but also what terms you’ll get. A lower score often means:
Higher interest rates
Larger deposits or guarantees
Loan rejections
Limited lender options
Some employers and landlords may also check your credit score before offering you a job or tenancy.

1. How low can a credit score go in NZ?
Credit scores can be as low as 0. Anything under 300 is generally considered very poor.
2. Will checking my own credit score lower it?
No. Checking your credit score is considered a soft inquiry and does not impact your score.
3. Can I improve a bad credit score?
Yes. Making on-time payments, reducing debt, and avoiding unnecessary credit applications can help over time.
4. How long does bad credit stay on your report?
Defaults and missed payments typically stay for 5 years, while bankruptcies can remain for up to 7 years.
