Balance Transfers Explained — A Step-by-Step Guide

If you're carrying credit card debt with high interest, a balance transfer can be a smart way to save money and pay down what you owe faster. This guide explains how balance transfers work in New Zealand, walks you through the process step by step, and helps you avoid common pitfalls.

What is a balance transfer?

A balance transfer is when you move debt from one credit card to another, usually to take advantage of a lower interest rate. In New Zealand, many credit card providers offer an introductory rate — often 0% or a very low rate — for a set period, typically 6 to 24 months.

During that promotional period, your repayments go directly toward reducing your principal balance rather than being eaten up by interest charges. This can help you clear debt faster and more affordably.

How does a balance transfer work in New Zealand?

Here's the basic process:

  • You apply for a new credit card that offers a balance transfer promotion.
  • If approved, you provide details of your existing credit card debt.
  • The new card provider pays off your old card(s) directly.
  • Your debt is now on the new card, at the promotional rate.
  • You make regular repayments during the promotional period.
  • Once the promotional period ends, the standard interest rate applies to any remaining balance.

Step-by-step guide to doing a balance transfer

Step 1: Check your current debt and credit score

Before applying, know exactly how much you owe and on which cards. You'll also want to check your credit score — a higher score improves your chances of approval for the best promotional rates. In New Zealand, you can check your credit score for free through services like Centrix or Illion.

Step 2: Compare balance transfer offers

Not all balance transfer offers are created equal. Look at:

  • Promotional interest rate — often 0% to 4% p.a. for a set period
  • Length of the promotional period — from 6 to 24 months
  • Balance transfer fee — typically 1% to 3% of the amount transferred
  • Annual fee — some cards waive the first year, others charge from $30 to $150+
  • Standard interest rate after the promo ends — usually around 18% to 22% p.a.

Step 3: Apply for a new card

Once you've chosen an offer, apply directly with the provider. You'll need to provide personal details, income information, and the amount you want to transfer. Most NZ banks and credit card issuers let you apply online.

Step 4: Initiate the transfer

After approval, you'll need to tell the new provider where to send the funds. You'll provide your old card number, the amount to transfer, and sometimes the BIC and account number for payment. The new card issuer handles the payment directly to your old card.

Step 5: Close your old card (or don't)

Once the balance is transferred, you can close your old card to avoid temptation. However, if it's a card you've had for a long time, keeping it open may help your credit score by maintaining your credit history. Weigh the pros and cons based on your spending habits.

Step 6: Make regular repayments

Set up automatic payments to ensure you never miss a minimum payment. Missing a payment can void the promotional rate, and you could be charged penalty interest. Aim to pay more than the minimum to clear the balance before the promo ends.

Step 7: Pay off the balance before the promo ends

This is the most important step. Calculate how much you need to pay each month to clear the debt before the promotional period expires. Use a simple formula:

Monthly payment = Total balance ÷ Number of months in the promo period

For example, if you transfer $3,000 with a 12-month 0% offer, you need to pay $250 per month to be debt-free by the end.

Key features of balance transfers in New Zealand

  • Promotional interest rates — typically 0% to 4% p.a. for 6–24 months
  • Balance transfer fees — usually 1% to 3% of the amount transferred
  • Annual fees — range from $0 to $150 depending on the card
  • Minimum repayment — usually 1% to 3% of the balance or a fixed amount (e.g., $25)
  • Standard rate after promo — typically 18% to 22% p.a.

Pros and cons of balance transfers

Pros Cons
Save money on interest during the promo period Balance transfer fees can eat into savings
Consolidate multiple debts into one payment Promotional rates are temporary
Faster debt repayment if you stick to a plan Missed payments can void the promo rate
Can improve credit utilisation ratio May encourage more spending if old card stays open
Simple to set up through most NZ banks Not all debt is eligible (e.g., store cards, personal loans)

Fees to watch out for

  • Balance transfer fee — charged as a percentage of the amount transferred (e.g., 1% on $5,000 = $50)
  • Annual fee — some cards charge this upfront, others waive it for the first year
  • Late payment fee — typically $20 to $50 if you miss a minimum payment
  • Cash advance fee — if you use the card for cash withdrawals, expect a fee (usually 1% to 5%) and higher interest

Who is a balance transfer for?

Balance transfers work well for people who:

  • Have existing credit card debt with high interest rates
  • Can commit to regular repayments during the promo period
  • Have a good credit score and can qualify for the best offers
  • Are disciplined about not accumulating new debt on the old card

Balance transfers are not ideal if:

  • You're likely to miss payments or only pay the minimum
  • You plan to make new purchases on the new card (purchases may not earn the promo rate)
  • Your debt is too large to clear within the promo period
  • You have a poor credit history that limits your options

Tips for success

  • Read the fine print — check what happens if you miss a payment or if the promo applies to new purchases
  • Set a repayment goal — divide your debt by the number of months in the promo period and set up automatic payments for that amount
  • Avoid new spending — use the new card only for the balance transfer, not for everyday purchases
  • Consider closing the old card — if you're tempted to spend, close the account to remove the temptation
  • Shop around — compare offers from ANZ, ASB, BNZ, Kiwibank, Westpac, and other NZ providers

Common mistakes to avoid

  • Only paying the minimum — this won't clear the debt before the promo ends, and you'll be hit with high interest
  • Transferring too much — if you can't afford the repayments, you'll end up worse off
  • Ignoring the balance transfer fee — a 2% fee on $10,000 is $200, so factor that into your savings
  • Using the new card for spending — purchases may not attract the promo rate and can complicate repayment
  • Not checking eligibility — some cards exclude certain debts (e.g., store cards, personal loans)

Verdict

Balance transfers can be a powerful tool for reducing credit card debt in New Zealand — but only if you use them strategically. The key is to choose an offer with a low or 0% promotional rate, a reasonable fee, and a long enough period to clear your debt. Then commit to making regular, meaningful repayments.

If you can do that, a balance transfer can save you hundreds or even thousands of dollars in interest. If you can't, you may end up paying more in fees and penalty rates. As with any financial product, do your research and consider your own situation before proceeding.
