The primary difference between Gem Visa and Q Card lies in their standard interest-free offerings. Gem Visa offers 6 months interest-free on any Visa purchase over $250 anywhere in the world. Conversely, Q Card (Q Mastercard) typically offers 3 months no payments and no interest on purchases, with longer terms dependent on specific retailer partnerships. Both carry high interest rates (approx. 28-29%) once promotional periods expire.
Gem Visa vs Q Card: The Core Differences
In the New Zealand personal finance landscape, “store cards” have evolved into powerful credit cards that function on the global Visa and Mastercard networks. The two giants dominating this space are Latitude Financial’s Gem Visa and the Humm Group’s Q Card (specifically the Q Mastercard).
While both cards are marketed heavily at checkout counters in major retailers like Harvey Norman, Noel Leeming, and PB Tech, they serve slightly different consumer behaviors. Understanding the nuances between them is critical, as choosing the wrong one can lead to significant interest charges.
Both cards operate on a similar premise: they offer long-term finance deals to help consumers purchase big-ticket items like furniture, dentistry, or electronics, spreading the cost over time. However, they differ significantly in how they handle “everyday” purchases and the fees associated with setting up these finance plans.

Interest-Free Terms Comparison
The primary allure of these cards is the interest-free period. This is where the battle of “Gem Visa vs Q Card” is usually won or lost depending on your spending habits.
Gem Visa: The 6-Month Rule
Gem Visa has a very clear, aggressive value proposition: 6 months interest-free on any Visa purchase over $250. This applies to any retailer worldwide that accepts Visa, not just partner stores.
- Mechanism: If you buy a $300 jacket or pay a $400 car repair bill, it automatically converts to a 6-month interest-free plan.
- Standard Purchases: For purchases under $250, you typically get up to 55 days interest-free (standard credit card terms).
Q Card / Q Mastercard: The 3-Month Breather
Q Mastercard generally offers 3 months no payments and no interest on standard purchases. This is distinct from Gem because it often allows you to defer the payment entirely for that quarter, whereas Gem requires minimum monthly payments during the interest-free period.
- Long-Term Finance: Q Card is famous for its specific retailer deals, often offering 12, 24, or even 50 months interest-free during special promotion periods at specific merchants.
- Flexibility: The “no payments” feature of Q Card can be attractive for cash-flow management, but it carries the risk of a ballooning balance if not managed disciplinedly.
Annual Fees and Establishment Fees
Beyond the interest rates, the fee structures for these cards can eat into the value of any “deal” you think you are getting. In New Zealand, these fees are subject to change, but generally hover around the following benchmarks.
Annual Fees
Both cards charge an account fee simply for keeping the line of credit open.
- Gem Visa: Approximately $55 NZD per annum (charged $27.50 half-yearly).
- Q Mastercard: Approximately $50 NZD per annum (charged $25 half-yearly).
Establishment Fees
This is a critical differentiator. When you utilize a “Long Term Finance” plan (e.g., 24 months interest-free on a TV), you are often charged an establishment fee.
Q Card is notorious for charging an establishment fee (often around $55) for new Long Term Finance plans, or a $35 advance fee for existing cardholders adding a new plan. If you buy five items on finance over a year, these fees add up rapidly.
Gem Visa also charges establishment fees ($55) for new customers, but for existing customers utilizing the standard 6-month interest-free offer on purchases over $250, there is typically no additional establishment fee, as it is a standard feature of the card. However, specific longer-term retailer plans (e.g., 12 months+) may incur a processing fee.

Interest Rates: The Cost of Carrying a Balance
If you fail to pay off your balance within the interest-free period, both cards revert to an exceptionally high interest rate. This is how the providers make their profit.
The Interest Rate Trap
Compared to a standard low-rate credit card from an NZ bank (which might be 12.95% p.a.) or a standard card (19.95% p.a.), store cards are significantly more expensive.
- Gem Visa: Prevailing interest rate is approximately 29.49% p.a.
- Q Mastercard: Standard interest rate is approximately 28.50% p.a. for purchases, with cash advances often higher.
Warning: On a $2,000 balance, the difference between 13% and 29% interest is hundreds of dollars per year. These cards should strictly be used as transactional tools to leverage interest-free terms, never for long-term revolving debt.
Impact of Store Cards on NZ Mortgage Applications
In the current New Zealand housing market, governed by the Credit Contracts and Consumer Finance Act (CCCFA), lenders scrutinize expenses and liabilities more than ever. Holding a Gem Visa or Q Card can significantly impact your borrowing power.
The Credit Limit Factor
Banks assess your “potential” debt, not just your current debt. If you have a Gem Visa with a $10,000 limit, even if the balance is $0, the bank may treat that as a liability. They assume you could max out that card tomorrow.
A $10,000 credit card limit could reduce your mortgage borrowing power by roughly $40,000 to $50,000.
Application Strategy
If you are planning to apply for a mortgage in NZ soon:
- Close unused accounts: If you have an old Q Card you don’t use, close it formally and get a letter of closure.
- Reduce limits: If you need the card, request the limit be lowered to the minimum (often $1,000 or $2,000).
- Clean payment history: Late payments on these cards are recorded on your credit file (Centrix, Equifax, illion) and can be a red flag for mortgage lenders.

Late Payment Fee Structures
Missing a payment on these cards triggers a cascade of costs. It is not just about the interest; the administrative fees are punitive.
Gem Visa: Typically charges a late payment fee of around $15 if the minimum monthly payment is not received by the due date. Furthermore, missing a payment usually cancels any interest-free promotional period you are currently enjoying, causing back-dated interest to be applied to the account.
Q Card: Similarly charges a default fee (approx $15) for missed payments. They also have collection fees if the debt is passed to a collection status.
The “Back-Interest” Clause: This is a critical term to understand. On some finance contracts, if you do not pay the full balance by the end of the interest-free term, interest is charged from the date of purchase, not just from the end of the promotional period. Always check the fine print for “retroactive interest” clauses.
Alternatives: BNPL vs Store Cards
With the rise of Buy Now, Pay Later (BNPL) services like Afterpay, Zip, and Klarna, are store cards like Gem and Q still relevant?
BNPL (Afterpay/Zip)
- Pros: No interest, usually no annual fees, easy approval for small amounts.
- Cons: Short repayment terms (usually 6-8 weeks), lower limits (often capped at $1,000 – $2,000), late fees apply.
- Best for: Clothing, small electronics, everyday consumables.
Store Cards (Gem/Q)
- Pros: High limits (up to $30,000+), long terms (up to 50 months), accepted globally as Visa/Mastercard.
- Cons: High interest if mismanaged, annual fees, establishment fees.
- Best for: Renovations, dental surgery, high-end appliances, travel.

Final Verdict: Which Card Should You Choose?
The choice between Gem Visa and Q Card ultimately depends on your purchase frequency and the size of the items you intend to buy.
Choose Gem Visa If:
- You frequently make purchases between $250 and $1,000 at various retailers.
- You want a card that automatically applies interest-free terms without needing to ask the merchant for a specific deal.
- You travel and want the security of a standard Visa card with 6 months to pay off travel expenses over $250.
Choose Q Card (Q Mastercard) If:
- You are making a specific, very large purchase (e.g., $5,000+ for furniture or dental work) where the merchant is offering a specific long-term deal (e.g., 24 months interest-free).
- You prefer a “no payments” period where you don’t have to pay anything for the first 3 months (cash flow deferral).
- You shop frequently at Q Card partner networks that offer exclusive long-term deals not available on Gem.
Professional Advice: Regardless of which you choose, set up a direct debit for the monthly minimum immediately, and aim to pay the full balance before the interest-free term expires. If you cannot afford to pay it off in that time, the ~29% interest rate makes these some of the most expensive forms of debt in New Zealand.
Frequently Asked Questions
Is Gem Visa the same company as Q Card?
No. Gem Visa is provided by Latitude Financial Services. Q Card (and Q Mastercard) is provided by Consumer Finance Limited, a subsidiary of the Humm Group. They are direct competitors in the New Zealand market.
Does applying for both cards hurt my credit score?
Yes. Every time you apply for a credit card, a “hard enquiry” is placed on your credit file. Multiple applications in a short period can lower your credit score and signal financial distress to lenders.
Can I transfer a balance from Q Card to Gem Visa?
Generally, yes. Gem Visa often allows balance transfers from other credit cards or store cards. They may offer a low interest rate (e.g., 0% or 5.99%) for a set period on the transferred balance. However, a balance transfer fee usually applies.
What is the minimum payment on Gem Visa?
The minimum monthly payment is typically 3% of the closing balance or $20.00 (whichever is greater). However, paying only the minimum will not clear your debt before the interest-free period ends.
How do I close my Q Card account?
To close a Q Card account, you must pay off the balance in full. You then need to contact their customer support team via phone or secure email to request closure. It is recommended to ask for written confirmation of the account closure for your records.
Which card is better for dental or medical finance?
Both cards are widely accepted by dentists and audiologists in NZ. The “better” card depends on the specific practice’s partnership. Some dental clinics have exclusive 12-18 month interest-free deals with Q Card, while others prefer Gem. Always ask the clinic reception which card offers the best term at their location.
