Eligibility and documents: check the card issuer’s requirements

Interest.co.nz does not assess whether you qualify for a credit card. Before applying, check the chosen issuer’s age, residency or visa, income and credit-history requirements. There is no single eligibility standard covering every listed card.

Prepare details of your income, living expenses, existing debts and financial commitments. The issuer may request supporting bank statements and check your credit history, consistent with the FMA’s explanation of lending assessments. Ask which identity, address and income documents it accepts. A comparison listing or calculator result does not establish affordability or approval.

Who should use Interest.co.nz’s credit card comparisons?

The service suits people willing to research a shortlist and verify the details themselves. Your repayment habits should determine which features matter:

• Paying in full: Compare annual fees and benefits you will actually use, alongside the conditions for interest-free purchases.
• Carrying a balance: Prioritise the ongoing purchase rate and an affordable repayment plan over rewards.
• Moving existing debt: Compare the transfer fee, promotional period and rate on any remaining balance.

For a defined purchase with a planned repayment date, compare personal loan repayment options. For several existing balances, assess debt consolidation costs using the same repayment horizon; a smaller monthly payment can conceal a higher overall cost.

How to compare cards and apply

From comparison to application

1. Use the comparison table to identify cards matching your spending and repayment needs.
2. Open each shortlisted issuer’s official website. Confirm availability, current pricing, eligibility and promotional conditions.
3. Check repayment estimates using current rates, fees and minimum-payment rules.
4. Apply through the issuer’s available channels and review its disclosure documents before accepting.

A LoansFinder enquiry is a separate referral request. It is not an application to Interest.co.nz or confirmation that a particular card is available through our referral service.

Application and card delivery times

Interest.co.nz has no card approval or delivery timetable. Ask the issuer separately about assessment, additional documents, card delivery and balance-transfer processing.

Corrections, repayment support and complaints

For Interest.co.nz rate corrections, email updates@interest.co.nz. General enquiries can go to info@interest.co.nz or 09 360 9670. Its contact page explains the separate process for editorial complaints.

For payment difficulties, contact your card issuer early. MoneyTalks provides free financial mentoring on 0800 345 123; our debt management guide covers further options. Raise card complaints with the issuer first, then seek help from its financial dispute resolution scheme if needed.

Questions to ask the card issuer before accepting

• What rates apply to purchases, cash advances and transferred balances, and when can they change?
• What fees apply over a full year, including additional cards, foreign transactions and missed payments?
• What must I repay to retain interest-free purchases, and how are payments allocated between balances?
• What will remain owing when a transfer promotion ends, and which rate applies then?
• Is any insurance compulsory or optional, what does it cost, and what activation rules, excesses and exclusions apply?

Interest.co.nz comparison advantages and limitations

• Useful overview: Several issuers appear together, making differences in rates and headline features easier to identify.
• Free research access: You can review information before deciding whether to approach an issuer.
• Pricing needs verification: The TSB spot-check below found a material difference from the issuer’s published rate.
• Calculator inconsistencies: The calculator page’s table gives ANZ’s minimum payment as 3% or $10, while its explanatory text refers to 2% and $5. Confirm current issuer rules before relying on an estimate.
• Limited decision support: A table cannot establish your approval prospects, total repayment cost or eligibility for insurance benefits.

Interest.co.nz fees and the cost of a shortlisted card

Interest.co.nz’s comparison service is free. The borrowing costs arise from whichever card you choose: interest, recurring card fees, transaction charges, applicable default fees and any separately charged insurance. Its terms describe rates as indicative and direct readers to confirm details with the financial institution.

Verified comparison example: a conflicting TSB rate

On 23 October 2026, Interest.co.nz listed TSB Low Rate Mastercard purchase and cash-advance rates of 9.95%. TSB’s own product page and pricing schedule both showed 11.95% p.a., with a $20 annual card fee and other charges where applicable. The two-percentage-point difference makes the comparison entry unsuitable as a current quotation. These are TSB product details, not an Interest.co.nz offer.

Compare the cost of your repayment plan

A purchase rate is not a fee-inclusive APR or a total repayment figure. Compare shortlisted cards using the same starting balance, planned payments and new-spending assumptions. Include fees over the expected repayment period and any post-promotion interest.

Interest-free days also require care. Westpac’s explanation shows why “up to 55 days” depends on purchase timing and repayment conditions. Cash advances do not receive those purchase interest-free days. Paying only the minimum can extend repayment and increase interest costs.

Verdict: useful for shortlisting, with verification required

Interest.co.nz’s strongest feature is a free overview of several issuers. Its main weakness is the gap between comparison data and confirmed product terms, demonstrated by the rate discrepancy and calculator inconsistency. Base the final choice on issuer documents and the cost of your intended repayment plan.

Interest.co.nz credit card comparison FAQs

Does using Interest.co.nz give me a better credit card deal than applying directly?

Interest.co.nz provides free comparison information, but its listings do not establish access to negotiated rates or exclusive offers. The issuer determines your credit limit, approval and applicable terms. Use the comparison to identify alternatives, then check the issuer’s current offer, including whether a promotion is restricted to new customers, particular application channels or qualifying transfers.

How reliable are the credit card rates shown on Interest.co.nz?

Treat them as a starting point for research. On 23 October 2026, its comparison listed TSB Low Rate Mastercard at 9.95% for purchases and cash advances, while TSB’s official pricing showed 11.95% p.a. for both. Interest.co.nz’s terms describe listed rates as indicative. Verify the exact card, current rate and promotional conditions before calculating savings.

Should I choose a lower interest rate or a card with no annual fee?

Compare the extra fee with the interest you expect to save. Illustration: a card costing an extra NZ$50 annually but charging five percentage points less interest would roughly offset that fee at an average interest-bearing balance of NZ$1,000 over a year. This simplified calculation excludes compounding and other charges. If you usually repay in full and qualify for interest-free purchases, a lower purchase rate may provide little benefit.

How can I tell whether a rewards card offers better value?

Calculate rewards from your normal eligible spending, using the value you can realistically redeem. Subtract annual fees, relevant transaction charges and expected interest. Check earning caps, excluded transactions, expiry rules and redemption restrictions. Assess introductory bonuses separately from ongoing value: a card can look attractive in its first year and become expensive after the bonus or fee waiver ends. Spending more to reach a reward threshold reduces the benefit.

How should I compare a short 0% balance transfer with a longer low-rate offer?

Compare both over the time you realistically need to repay, including transfer fees, recurring card fees and interest after the promotion. A short 0% offer can become more expensive if substantial debt remains when its standard rate starts. Also check repayment allocation and new-purchase interest. For example, ANZ states that repayments generally reduce transferred balances first, and new purchases receive no interest-free days until the transferred balance is fully repaid. Other issuers’ rules may differ.

Is a card with 55 interest-free days better than one with 44?

Only if you meet the conditions and benefit from the extra payment time. These are maximum periods, not the allowance for every purchase; buying later in a statement cycle gives you fewer days. Compare the statement date, payment deadline and full-balance repayment requirements. If you carry debt and lose purchase interest-free days, the ongoing interest rate can matter more than the advertised number of days. Cash advances require separate comparison.

Can Interest.co.nz help me identify which cards I qualify for?

Its rate table does not assess eligibility, and issuer requirements can differ materially. For example, ANZ publishes a work-visa route for visas issued for at least two years with at least one year remaining, while TSB Low Rate Mastercard’s criteria specify New Zealand citizens or resident visa holders living in New Zealand. Other lending criteria apply. With impaired credit, ask about eligibility before submitting applications; a low advertised rate does not indicate easier approval.

How should I use the repayment calculator to compare providers fairly?

Use the same starting balance and affordable monthly payment for each card. Comparing each issuer’s minimum payment can favour a card that simply takes longer to repay. Include annual fees, promotional expiry and planned new spending. Interest.co.nz’s calculator page contains conflicting ANZ minimum-payment figures between its table and explanatory text, so verify repayment rules against the issuer’s current agreement before relying on an estimate.

What should I compare beyond the headline rates and card fee?

For overseas spending, check foreign-currency charges and the exchange-rate method. For cash withdrawals, check transaction fees and when interest starts. For insurance benefits, verify activation requirements, exclusions, excesses and claim limits before assigning them a value. Confirm whether a displayed card fee is annual or charged more frequently, and distinguish blank comparison fields from confirmed zero charges. The issuer’s full fee schedule and policy wording are needed to assess these costs and benefits.
