What Is Amortisation in New Zealand Accounting? Definition, Examples & How It Differs from Depreciation

Amortisation is the process of gradually expensing the cost of intangible assets, such as software, goodwill, or trademarks, over their useful life. In New Zealand, amortisation ensures expenses are matched with the revenue they help generate.

This method allows businesses to spread large intangible costs fairly over time, improving accuracy in financial reporting.
