How to fix a bad credit score in NZ

A bad credit score is rarely one problem. It is usually a few items on a file that each have a different fix, and some have no fix except time. Sorting them into those two piles is the most useful thing you can do. After that, the work is mostly dull and steady, which is how a file gets rebuilt.

What you can change and what you cannot

Item on your file	Can you change it?	What helps
A listing that is wrong or not yours	Yes, and it is free	Ask the organisation that supplied it, and the credit reporter, to correct it
An accurate default	No, it stays up to five years	Pay it, show it is settled, wait
Late payments	Not the past ones	Pay on time from now on
Many recent applications	Only by waiting	Stop applying for credit
High balances on cards or loans	Yes	Pay them down
No history at all	Yes	Build one, see car finance with no credit history

Consumer Protection describes a default as a payment of more than $125 that is over 30 days late, where the lender has tried to recover it. It stays on your record even if you repay it in full. That surprises many people, and it is why paying a default is about your next application, not about wiping the slate.

Step 1: get all three reports

Start with the facts. The three reporters each hold their own file, so an error can sit on one and not the others. Our guide on how to check your credit score covers where to order each, so we will not repeat it here. Requests should be handled within 20 days, according to Consumer Protection, and checking your own file is not a lender enquiry.

Go through each report with a pen. Mark anything you do not recognise, any wrong date or balance, and any account you closed that shows as open.

Step 2: correct mistakes first

This is the only part that can move fast. Consumer Protection sets out the path:

1. Contact the organisation that supplied the wrong information. Explain the problem and give evidence such as a statement or a receipt.
2. That organisation must investigate and correct errors, and the correction should flow through to all credit reporters.
3. You can also complain to the credit reporter, which must check with the source.
4. If a refusal seems unjustified, you can complain to the Privacy Commissioner.

Keep copies of everything you send. If you see accounts you never opened or enquiries you did not agree to, treat it as possible identity fraud. You can ask a credit reporter to freeze your file for 10 days and add an alert, and Consumer Protection says freezing with Centrix or Equifax covers both.

Step 3: deal with debts that are still open

An unpaid default or a debt in collections will weigh more than a paid one. If you cannot clear it, call the creditor and ask for a payment plan. Centrix suggests that if there is a cashflow disruption, you try to negotiate longer payment terms upfront, which limits the effect on your score. MoneyTalks, on 0800 345 123, can help you talk to a lender, and the service is free and confidential.

Avoid the quick fixes. Consumer Protection lists payday and quick-finance loans among things that can be viewed negatively, and borrowing to pay off a default usually swaps one problem for a worse one.

Step 4: make every payment on time, from now on

On-time payment is the thing that rebuilds a file, and it covers more than loans. Sorted says power, phone and other utility payments can count under comprehensive credit reporting. Practical moves:

• Set automatic payments for rent, power, phone and any loan, timed for the day after payday.
• Keep a small buffer in the account so a payment does not bounce.
• If a bill will be late, contact the provider before the due date.
• Avoid shared bills where someone else’s missed payment could land on you.

Our page on bad credit score explains that repayment history is recorded for only a limited period, so a run of clean months does show up.

Step 5: stop applying for credit

Consumer Protection says applying for several sources of credit in a short time can lower your score, and gives four credit cards in three months as an example. If you want a car loan, this is the moment to pause other applications, including store cards and buy now pay later accounts. Our page on whether applying for car finance affects your score covers how to compare lenders without piling up enquiries.

A month by month plan

This is an example for someone planning to buy a car in about a year. Adjust it to your own dates. It is a plan, not a prediction of any score.

When	What to do
Month 1	Order all three reports. Mark errors. Send correction requests with evidence.
Month 2	Follow up. Set automatic payments. Call any creditor about open debts.
Months 3 to 6	Pay on time every time. Pay down the smallest balance. Save a few hundred dollars toward a deposit.
Months 7 to 10	Order the reports again to see what changed. Question anything still wrong.
Months 11 to 12	Work out a weekly budget, choose a car price, then talk to a lender or broker.

If your car is needed sooner, you do not have to wait for a perfect file. Lenders weigh income, costs and the car as well, as our page on what credit score you need for a car loan explains.

Does a car loan itself help?

It can, if you pay every instalment on time, because a repayment record is built month by month. The risk is the other direction: a loan you cannot keep up with adds new missed payments to a file that already has some. Choose a repayment that leaves room, and consider a cheaper car or a deposit to keep the loan small. Our car loan with bad credit guide shows what a higher rate does to the total.

What to expect, honestly

Rebuilding is slower than damaging. A default can cut a score quickly, while building it back takes steady months. That is frustrating, and it is also why it pays to avoid shortcuts. Three things to keep in mind:

• Different reporters, different numbers. Each company scores in its own way, so your three scores will not match. Watch the direction of each over time, not one figure.
• Lenders read the history, not just the number. A default from three years ago with two clean years since looks different from one last spring, even when the score is similar.
• You do not have to be finished to apply. A file that is visibly improving, with errors fixed and open debts handled, reads better than one left alone. The sooner you start, the sooner that story begins.

Do not stretch yourself to speed things up. Paying a credit card down by skipping rent creates a new missed payment, which is worse than the balance you cleared.

Free help to get started

A financial mentor can go through your reports with you, help you write to a creditor and set up a budget that makes on-time payment realistic. MoneyTalks is free and confidential, and Sorted has guides and a budgeting tool. If a debt feels unmanageable, a budgeting service can also talk about options such as a payment arrangement, before the situation gets harder to fix.

Checklist

• All three reports ordered and read.
• Every error flagged, with evidence sent.
• Open debts have a plan or a call logged.
• Automatic payments set up.
• No new credit applications for now.
• A realistic car budget worked out.

Red flags in credit repair offers

Walk away from anyone who promises to delete accurate negative items, asks for money up front, tells you to dispute everything whether or not it is wrong, or suggests creating a new identity. Real corrections are free and come from the organisation that listed the item. If you have already paid a company and are unsure, free advice is available from Citizens Advice Bureau and MoneyTalks.
