Finding the right place to store and grow your business’s surplus cash is more than just chasing the highest rate of return. In 2026, there are a number of different types of savings options for Kiwi businesses, each with their own features that can suit your business goals.

This guide compares the best business savings accounts alongside modern alternative options to help you maximise your returns while maintaining the essential cash flow your business needs to thrive.

What is a business savings account?

A business savings account is a separate account used to earn interest on funds not required for your daily operations. While your transaction account handles the heavy lifting of payroll and supplier payments, the savings account acts as a holding place for GST reserves, provisional tax, or future expansion capital. By moving surplus cash into a dedicated saver, you are able to earn a rate of return on the funds held in that account.

Types of business savings accounts in New Zealand

Understanding the different account types is essential for managing your cash flow effectively. In New Zealand, you generally choose between four main structures:

On-call accounts

These are the most flexible option for businesses that need instant access to their cash. You can typically move money back into your transaction account immediately, making them ideal for tax "buckets" where the withdrawal date might be unpredictable.

Notice saver accounts

Notice savers offer a middle ground between flexibility and higher returns. To withdraw your funds, you must give the provider a set notice period – typically 32, 60, or 90 days. If your business can afford to wait, these accounts often provide a higher interest rate than standard on-call options.

Term deposits

A term deposit locks your money away for a fixed period, ranging from a few months to several years. While they offer certainty with a fixed interest rate, the lack of liquidity can be a risk if your business faces an unexpected expense or a sudden opportunity for growth.

Yield and Growth accounts

Offered by financial platforms including Airwallex and Emerge, Yield or Growth accounts are a modern alternative to traditional bank savings. They often provide competitive returns by investing in low-risk assets while maintaining high liquidity. Airwallex’s Yield account also allows you to earn returns on multiple currencies.

The best business savings accounts and savers in NZ

When comparing options for 2026, it is important to look at the rate of return alongside the ease of access. Here is how the top New Zealand providers compare:

Features to look for in a business savings account

Choosing an account is about more than just finding the highest rate of return – here are the features to look at when comparing savings accounts.

Interest rate, rate of return, and tiers

Not all interest rates are created equal. Some banks only offer their headline high rates if you make no withdrawals, or that you stick to certain requirements.. Always check if there are tiered structures that could penalise you for having a smaller balance.

Accessibility and notice periods

Liquidity is the lifeblood of a growing business. Before committing to a notice saver or term deposit, determine if your business can truly afford to wait 32, 60, or 90 days for your cash. If you are in a fast-moving industry, a "no lockup" account or an on-call account is usually the safer bet.

Software integration

Your financial tools should talk to each other. Check if the account comes connected to a business transaction account or if it can sync seamlessly with your accounting software, such as Xero or MYOB. Automated bank feeds save hours of manual reconciliation and reduce the risk of human error.

Additional tools from the financial platform

A savings account shouldn't exist in a vacuum. Consider what other features the provider offers. Can you easily move funds into a transaction account? Can you easily check your balance and interest earned through an app? A holistic financial platform can often provide more value than a standalone savings account at a traditional bank.

Does my business need a savings account?

While there is no legal requirement for a New Zealand business to hold a savings account, it is a great way to earn money from your funds while you’re not using it. Using a separate account to grow idle business funds ensures you aren't "accidentally" spending money that should be reserved for the IRD or future capital expenditure. It provides a buffer and turns your dormant cash into a productive asset.

Frequently asked questions

What is a good interest rate for a business savings account in NZ?

Can a sole trader open a business savings account?

Yes, sole traders can open business-specific savings accounts. Keeping your business and personal finances separate is a best practice for simplifying your tax obligations and tracking your business growth.
