What Is a Bad Credit Score and What Causes It in New Zealand?

Learn what affects your credit score, what’s considered “bad,” and how it impacts your financial life in NZ.

Your credit score is more than just a number — it’s a financial reputation. In New Zealand, lenders use this score to determine how trustworthy you are with borrowing. A bad credit score can be a major roadblock to getting a loan, mortgage, or even renting a home. In this article, we break down what causes a bad credit score and how it affects your daily life.

What Is a Credit Score?

A credit score is a three-digit number between 0 and 1000 (depending on the credit reporting agency). It reflects your credit history — how reliably you’ve repaid money you’ve borrowed. The lower the number, the riskier you appear to lenders.

What Is Considered a Bad Credit Score in NZ?

While different agencies have slightly different ranges, here’s a general breakdown:

• Excellent: 800–1000

• Good: 700–799

• Fair: 500–699

• Poor / Bad: Below 500

A score under 500 typically indicates missed payments, defaults, or financial issues in the past.

What Causes a Bad Credit Score?

Several common behaviours or financial events can cause your credit score to drop:

1. Late or Missed Payments
   Even one missed payment on a loan, credit card, or utility bill can be reported.

2. Defaults
   If a debt goes unpaid for too long, the lender may list it as a default on your credit report.

3. Too Many Credit Applications
   Applying for several loans or credit cards in a short time can make you appear desperate for credit.

4. Court Judgments
   If a lender takes legal action and wins a court judgment against you, it will stay on your report for years.

5. Bankruptcy or Insolvency
   These are major red flags to lenders and stay on your file for up to 7 years.

6. High Credit Usage
   Constantly maxing out your credit limit or having high balances can signal financial stress.

7. Lack of Credit History
   Ironically, having no credit history at all can also result in a low score, as lenders can’t assess your risk.
