What Is Cost of Goods Sold (COGS) in New Zealand? Definition, Formula & Examples

Cost of Goods Sold (COGS) represents the direct costs of producing or purchasing the goods a New Zealand business sells. It includes raw materials, direct labour, and related expenses, but excludes overheads like rent or admin.

In NZ, COGS is deducted from sales revenue to calculate gross profit, making it a key metric for pricing, profitability, and tax compliance.
