What Is a Debit Note in New Zealand? Definition, Purpose & Examples

A debit note in New Zealand is a document issued by a buyer to a supplier to formally request a reduction in the amount payable. It is commonly used when goods are returned, damaged, or invoiced incorrectly.

Debit notes act as a counterpart to credit notes and ensure that accounts payable and receivable are adjusted accurately in line with NZ accounting standards and IRD rules.
