What Is Double-Entry Accounting in New Zealand? Definition, Rules & Examples

Double-entry accounting is the foundation of modern bookkeeping in New Zealand. Every transaction records at least two entries — a debit in one account and a credit in another — ensuring the accounting equation (Assets = Liabilities + Equity) always balances.

This system improves accuracy, reduces fraud risk, and is required for NZ businesses preparing financial statements under accounting standards.
