Quick answer

A business line of credit gives a New Zealand business an approved limit it can draw on, repay and draw again, paying interest only on what's used. It suits repeating gaps such as waiting on customers, buying stock ahead of busy months or paying wages before progress payments. Lenders set the limit from bank statements and trading history, and many charge a fee to keep the facility open even when it's unused.

Key points

  • Interest is charged on the drawn balance, not the full limit.
  • Best for gaps that come and go, not one-off purchases.
  • Limits are set from bank statements and trading history.
  • Ask about line fees, draw fees and annual reviews.

Some cash flow problems happen once. Others happen every month: the wages go out on Thursday, but the big customer pays on the twentieth; the stock has to be bought in August for sales in November. Taking out a fresh loan every time that happens is expensive and tiring. A line of credit is built for the gaps that keep coming back.

How it works

You’re approved for a limit, say $40,000. You draw what you need, when you need it, and repay it as money comes in. Once repaid, the limit is available again. Interest is charged only on what’s drawn, for as long as it’s drawn.

Feature Line of credit Term loan
Funds Draw as needed up to a limit Paid in one lump sum
Interest On drawn balance only On the full loan
Repayment Flexible, often a minimum each month Fixed schedule
Best for Repeating, uneven gaps One-off costs

What lenders look at

The limit depends mostly on how your business trades. Expect a lender to review six to twelve months of bank statements, check that GST returns are filed, look at your credit files and ask about existing debts. Some will want to see an aged debtors list, especially if the gap is caused by customers paying on long terms. A steady account with regular deposits supports a higher limit than one that swings wildly.

Costs to ask about

Lines of credit can carry costs that term loans don’t:

  • Line or facility fees, charged on the limit whether you use it or not.
  • Draw fees, charged each time you take funds.
  • Annual review fees when the facility is renewed.
  • Interest on the drawn balance, which may be calculated daily.

Add these up for the way you’d actually use the facility. A line you dip into twice a year might cost more in fees than it saves in interest.

Using it well

The discipline is to treat the limit as a bridge, not a balance. Draw for a specific gap and repay when the money lands. If the balance never comes down, the facility is funding a loss rather than a timing gap, and that’s a sign to look at pricing, costs or a longer-term working capital loan instead. Keeping GST and PAYE in a separate account helps too, so tax money isn’t quietly propping up the limit.

An illustrative example

A Nelson landscaping business with six staff pays wages weekly but is paid by property developers on 30 to 45 day terms. Every month it’s short for about three weeks. It arranges a $35,000 line of credit, draws $20,000 to $30,000 when invoices are outstanding and repays as each developer pays. Over a year, the average balance is around $12,000, so it pays interest on that rather than on a $35,000 loan. Illustrative only.

When a line of credit isn’t the answer

If you’re buying something that lasts years, a vehicle or machine, use equipment finance instead. If the gap is a single large one, such as a tax bill or one big order, a short term loan may be simpler and cheaper. And if the balance never clears, it’s worth talking to your accountant about whether the business has a cash flow problem or a profit problem; the fix is different.

Getting a limit increased later

Lenders are usually happy to review a limit once you’ve run the facility well for six to twelve months. Repaying on time, keeping the balance moving and showing growth in deposits all help. Ask what the review process is before you sign, so you know what to aim for.

Secured or unsecured lines

Most lines of credit offered to smaller businesses are unsecured, backed by a director guarantee and sometimes a general security interest registered on the PPSR. Some lenders offer a larger limit secured over property, which can suit a business with bigger swings in cash flow, such as a seasonal exporter or a contractor carrying several jobs at once. A secured line usually costs less but puts the property at risk if the business can’t repay, so everyone on the title should understand the arrangement and get independent legal advice before signing.

Keeping the facility healthy

Lenders watch how a line is used. A balance that rises and falls with your trading looks like a well-run facility. A balance that sits at the limit for months, or repayments that only ever cover interest, can trigger a review or a reduced limit. Setting a simple rule, such as clearing the balance within sixty days of each draw, keeps you in control and makes renewal easier.

Frequently asked questions

How is a line of credit different from an overdraft?

They work in a similar way. A bank overdraft sits on your transaction account; a line of credit is usually a separate facility you draw from into your account. Specialist lenders often offer lines of credit to businesses a bank won't give an overdraft to.

Do I pay anything if I don't use it?

Sometimes. Some lenders charge a monthly or annual line fee regardless of use. Check before you sign.

Can the lender reduce my limit?

Usually, yes. Most facilities are reviewed periodically, and a limit can be reduced if trading weakens or repayments are missed.

Is a line of credit good for buying equipment?

Not usually. Equipment lasts years, so equipment finance over a matching term is normally a better fit.
