Your credit score is a numerical representation of your credit history and borrowing behaviour. Understanding what it means, how it's calculated, what affects it, and how lenders use it helps you make informed financial decisions and avoid behaviours that damage your ability to borrow when you need to. Credit scores aren't mysterious - they follow logical patterns based on how reliably you manage debt.
A credit score is a number that summarises your credit history and predicts how likely you are to repay borrowed money based on your past behaviour.
In New Zealand, credit reporting agencies collect and hold information about your borrowing and repayment behaviour.
Your track record of making payments on time is the single most important factor in your credit score.
Credit utilisation is how much of your available credit you're actually using.
If you have credit available, keeping balances well below limits demonstrates you're not desperately relying on borrowed money. Consistently maxing out cards signals financial stress.
Serious negative marks that significantly damage credit scores.
When you apply for credit, lender checks your credit file. This enquiry is recorded.
How long you've been using credit contributes to score.
Lenders use credit scores as one tool (among several) to assess whether to lend and what terms to offer.
Credit score isn't everything. Lenders also consider:
Truth: Checking your own credit report and score is a "soft enquiry" and does NOT affect your score. You can and should check regularly.
Truth: Closing accounts can sometimes LOWER your score by reducing total available credit (increasing utilisation) and shortening average account age. Keep old accounts with good history.
Truth: While late payments hurt, they don't permanently destroy credit. Impact diminishes over time, especially with subsequent good behaviour. Recent history weighted more heavily.
Truth: No credit history means no score, not a perfect score. Lenders can't assess risk without history. Some credit use and good repayment builds score.
Truth: Your salary doesn't directly affect credit score. Score based on borrowing behaviour, not income level. (Income matters to lenders separately from score.)
Truth: Paying a default changes status to "paid" but doesn't immediately remove it from credit file. Stays on record for period even after paid.
Truth: Different bureaus may have slightly different information and use different scoring models, resulting in different scores.
Credit scores are dynamic, not static. They update as new information is added to your credit file.
While specific timelines vary, the principle is consistent: recent behaviour matters most. Start building positive history now, maintain it consistently, and score will improve over time. The damage from past mistakes gradually fades as you demonstrate sustained reliability.
Final insight: Credit scores represent your borrowing reliability based on past behaviour patterns. They're calculated by credit bureaus from information lenders report about your accounts, repayments, defaults, and credit applications. Most important factor is payment history - consistent on-time payments build good credit, while late payments and defaults damage it. Credit utilisation, enquiries, and length of history also matter. Lenders use scores to assess risk and determine lending terms. Common myths like "checking own score hurts it" or "closing cards improves score" lead to poor decisions. Improve credit through consistent payments, manageable balances, avoiding defaults, and limiting applications. Scores change as new information added - they're not permanent judgements. Emotional reactions to poor credit understandable but focus on improvement actions. Short-term damage from mistakes can be repaired with sustained good behaviour. Check your credit report regularly, dispute errors, and commit to building positive history going forward. Recovery is possible and many have successfully rebuilt credit from difficult starting points.
