Selecting the right payment gateway for your Kiwi e-commerce store directly impacts your bottom-line profit margins and checkout conversion rates. High processing fees eat away at tight retail margins, while an unfamiliar or cumbersome checkout process causes Kiwi shoppers to abandon their carts. Here is a definitive, transparent breakdown of the four major payment solutions in New Zealand.
Unlike the United States where credit card rewards dominate, New Zealand consumer payment habits are characterized by heavy debit card usage and increasing mobile wallet adoption (Apple Pay and Google Pay).
When evaluating a payment gateway for your Kiwi business, you must assess four factors: transaction fees, setup complexity, payout settlement velocity, and consumer trust.
Here is how the four primary gateways compare for New Zealand merchants in 2026:
| Gateway | Transaction Fees (Domestic Cards) | Setup Complexity | Payout Speed | Best For |
|---|---|---|---|---|
| Stripe NZ | 2.7% + $0.30 NZD | Instant (minutes) | Rolling 2 business days | Modern startups, Shopify, WooCommerce |
| Windcave | Custom (~1.5% - 2.2% + gateway fee) | High (merchant account required) | Next business day | High-volume merchants ($30k+/mo) |
| PayPal NZ | 3.4% + $0.45 NZD | Easy | 1-3 business days | International buyers, marketplace trust |
| POLi Payments | 1.0% (capped at $3.00 NZD) | Moderate | Daily batch | Debit card shoppers, high-ticket goods |
> Kiwi Fee Insight: For transactions over $300, POLi's $3.00 flat fee cap offers significant savings compared to credit card processing fees.
Stripe remains the easiest and most versatile gateway to implement:
Formerly known as Payment Express, Auckland-headquartered Windcave is the dominant player in corporate New Zealand retail:
Infynt ensures your checkout process delivers maximum conversion with minimal friction. We integrate dual payment options—such as Stripe with Apple Pay alongside POLi for direct bank transfers—giving Kiwi shoppers their preferred payment method while keeping processing fees lean.
We engineer custom, blazing-fast websites and Shopify stores for Palmerston North and New Zealand businesses. Transparent fixed pricing, 40/30/30 milestone payments, and 100% code ownership.
No. Stripe operates as a payment aggregator, allowing you to accept payments immediately and deposit funds directly into any standard New Zealand business bank account.
If you sell consumer retail goods priced between $50 and $250, offering Afterpay can boost average order values by 20–30%. However, be mindful that BNPL merchant fees range between 4% and 6%.
Many Kiwis prefer not to use credit cards to avoid debt, and POLi allows them to pay instantly and securely from their internet banking account without entering card details.
