Best Business Credit Cards
in New Zealand (2026)

Choosing the right business credit card in New Zealand can save you hundreds of dollars a year, improve your cash flow and turn everyday expenses into flights, cashback or statement credits. But with offerings from ANZ, BNZ, Westpac, ASB and American Express all competing for attention, it can be hard to know where to start.

We reviewed every major business credit card on the New Zealand market in early 2026 and put them through a side-by-side comparison. Below you will find the full table, our top picks for different business needs, and a practical strategy for getting the most value.

Why your business needs a credit card

Interest-free cash flow. Most business cards offer 44 to 55 interest-free days. That means you can pay a supplier today and not owe the bank a cent for up to eight weeks — as long as you pay the full balance by the due date. For businesses bridging the gap between paying costs and receiving revenue, this is effectively free short-term finance.

Earn on every dollar. Whether it is fuel, office supplies, software subscriptions, vehicle maintenance or advertising, a rewards card turns routine spending into Airpoints Dollars, cashback or points that can be redeemed for travel and statement credits.

Separate your finances. A dedicated business card simplifies GST returns, tax claims and bookkeeping. Cards from AMEX and ASB can export transactions directly into MYOB, Xero and Excel.

Travel and purchase protection. Several cards include complimentary overseas travel insurance, purchase protection and extended warranty cover at no extra cost — benefits that would otherwise cost hundreds of dollars a year.

Full comparison table

The table below compares eight business credit cards from six providers across the key features that affect your bottom line: annual fees, interest rates, interest-free days, rewards earning, travel insurance and network acceptance.

* AMEX 3.25% is a liquidated damages charge for missed payments — not a standard revolving interest rate. AMEX expects the balance to be paid in full each month.

Best card for rewards — AMEX Gold Business

The AMEX Gold Business is the standout for pure earning power. No bank-issued card comes close to its 2x points rate, which is a result of AMEX being exempt from the Visa/Mastercard interchange fee caps that have forced banks to cut their rewards over recent years.

The main trade-off is acceptance. AMEX is widely accepted at major NZ retailers (Countdown, New World, BP, Z Energy, Mitre 10, Bunnings, and most chains) and works with Apple Pay and Google Pay. However, some smaller independent retailers, cafes and tradespeople may not accept it.

Best card for cashback — BNZ Advantage Visa Business

For businesses that deal with lots of small vendors — mechanics, parts suppliers, independent retailers — the BNZ Advantage Visa Business is the pick. You will never be caught out at a terminal that does not accept your card, and the cashback goes straight to your account rather than needing to be converted through a rewards portal.

One important note: BNZ devalued their personal Advantage credit card rewards by approximately 26% in February 2026. It is worth confirming directly with BNZ that the business card terms shown above remain current, as these may also be subject to change.

Best card for low interest — ANZ Visa Business Low Rate

If your business sometimes needs to carry a balance, the ANZ Visa Business Low Rate at 13.90% p.a. is the most affordable option. With a $35 annual fee — the lowest of any card in this comparison — it costs very little to hold. The trade-off is straightforward: no rewards, no travel insurance, no extras. It is a simple, cheap line of credit.

What $50,000 in annual spend earns you

To put the rewards in concrete terms, here is what each card returns on $50,000 of annual business spending:

AMEX calculated at 2 pts per $1 (Turbo rate, valid until 31 August 2026) valued at $0.75 per 100 points via AMEX Travel. BNZ cashback based on ~$1 per $75 spent. Airpoints Dollars valued at approximately $1 NZD each.

Cash flow comparison

If improving cash flow is your primary goal, interest-free days and the purchase rate matter more than rewards. Here is how the cards stack up:

Pro strategy: the two-card approach

If your budget allows, running two cards gives you the best of both worlds: maximum rewards on most spending and universal acceptance for the rest.

Combined annual fees come to just $180 ($145 + $35). On $50,000 of spending — even if only 70% goes through the AMEX — you would still earn over $500 in net rewards after fees. The ANZ Low Rate card handles the rest with universal Visa acceptance and the cheapest interest rate if you ever need to carry a balance.

If you can only hold one card and you deal with lots of small vendors, the BNZ Advantage Visa Business is the strongest single-card option: solid cashback, Visa acceptance everywhere, travel insurance included, and 50 interest-free days for cash flow.
