Gross domestic product, or GDP, measures the market value of goods and services produced in New Zealand. Stats NZ, the national statistics office, synthesizes business, household, price, government, and trade sources under 2008 SNA, the global accounting standard. The headline is production output in real chain-volume terms, meaning price change removed, adjusted for seasonal patterns, with spending and income splits alongside. It covers domestic output only, not welfare or nominal revenue at current prices, and not per capita or income power splits.
A positive quarterly change means growth versus the prior quarter, while a negative change means contraction. There is no publisher target band or trigger level.
