How to Read Your Bank Statement (NZ Guide)

Weekly insights on saving, spending, and making your money work harder. No spam.
Bank statements look like a foreign language. "POS TXN", "D/D", "ATM W/D" — what does it all mean? Understanding your statements is the first step to tracking your spending.
Here's your guide to reading a NZ bank statement like a pro.
The basics
Your bank statement shows every transaction in and out of your account for a specific period. Most NZ banks provide statements monthly, and you can view them in your banking app or download a PDF.
Key columns
- Date — when the transaction was processed (not necessarily when you made it)
- Description — the merchant, reference, or type of transaction
- Debit — money going out (spending, transfers, payments)
- Credit — money coming in (salary, transfers, refunds)
- Balance — your running total after each transaction
Common NZ transaction codes
POS (Point of Sale)
Any card payment at a physical terminal. "POS TXN COUNTDOWN RICCARTON" means you tapped your card at Countdown in Riccarton.
D/D (Direct Debit)
Automatic payments set up by a company to take money from your account. Power bills, phone plans, insurance — these are all D/D.
A/P (Automatic Payment)
Payments you've set up yourself to go out automatically. Rent, savings transfers, loan payments.
ATM W/D (ATM Withdrawal)
Cash withdrawn from an ATM. The location is usually shown.
TFR (Transfer)
Money moved between your own accounts or to someone else.
INT (Interest)
Interest earned on your account (credit) or charged on your overdraft (debit).
FEE
Bank charges — monthly account fees, transaction fees, dishonour fees.
Spotting problems
Unauthorised transactions
If you see a transaction you don't recognise, contact your bank immediately. NZ banks have fraud protection and will investigate.
Double charges
Sometimes a merchant charges you twice. Check for identical amounts on the same day. Contact the merchant first, then your bank if they don't resolve it.
Unexpected fees
Check for fees you didn't expect — overdraft charges, international transaction fees, or monthly account fees. You may be on the wrong account type. Compare NZ bank accounts to find a better fit.
Steady tip: Steady auto-categorises all your transactions and flags unusual patterns. Instead of reading through bank statements manually, you can ask the AI "Were there any unusual charges this month?" and get an instant answer.
Making statements useful
Reading bank statements is important but tedious. The modern approach is to let an app do it for you. Steady connects to your bank via open banking and turns that wall of transaction codes into a clear spending breakdown — by category, over time, with trends and insights.
No more squinting at "POS TXN" codes. Just clear answers about where your money goes. See how Steady works.
