A café bill of $18.47 is perfectly normal even though no current coin can pay the final seven cents. New Zealand removed its 5-cent coin in 2006, so card payments remain exact while cash totals are rounded to the nearest 10 cents. This tiny rule is one of the most useful pieces of local money knowledge a visitor can learn.
The last digit decides the cash total
Do not round every shelf label in your head
A supermarket can price one item at $3.99 and another at $2.48. The register adds the full prices first, then rounds the final cash amount once. Rounding each item separately can produce a different and incorrect answer.
Cash and card can produce neighbouring receipts
The difference is never more than five cents on a normal transaction, but it explains why two people buying the same basket can see slightly different totals. It is not a card discount or a hidden cash fee. It is the mechanical result of the smallest coin being 10 cents.
Legal tender does not force every till to accept cash
New Zealand banknotes and current coins are legal tender, but a business can set a card-only policy if customers are clearly told before they buy or receive the service. Check the sign before ordering at a cashless venue rather than invoking legal tender after the bill arrives.
A pocketful of coins has legal limits too
Legal-tender rules place limits on how much can be paid in each coin group: up to $5 in 10- and 20-cent coins, $10 in 50-cent coins, and $100 in $1 and $2 coins. A jar of change is therefore not an unlimited way to settle a large bill.
Keep the odd cents out of the travel budget
When estimating costs, use the exact advertised price and let the till perform any final cash rounding. Over a holiday the gains and losses usually balance around a few cents. The more important comparison is whether the venue adds a card surcharge or whether an ATM and your home bank both charge fees.
