Contribution to GDP of resource rent of New Zealand's natural resources

Resource rents: revenue generated from a resource less all costs incurred in its extraction; for all assets except fish, include a return to land.
Asset value: market price of an asset if it was sold.
Gross domestic product (GDP): New Zealand's official measure of economic growth.

Fish resource rent is calculated as the current value of the fish monetary stock. The figures for 'fish' relate to the year ended September.
Minerals resource rent is calculated using the residual value method for the metal ore and non-metallic mineral mining and quarrying industry.
Timber resource rent is calculated using the residual value method for the forestry and logging industry.

Asset values for total minerals are not yet available.
Resource rent for coal and oil and gas is not yet available.

Asset values (except timber) and resource rents have revised due to changes in input data and methodologies.

Environmental-economic accounts show how our environment contributes to our economy, the impacts of economic activity on our environment, and how we respond to environmental issues.

Environmental accounting is the measurement of environmental assets in monetary terms. It focuses on the value of an environmental resource and the changes in that value over time. One aim of environmental-asset accounting is to assess whether patterns of economic activity are depleting or degrading our resources. Information from an environmental-asset account can be used to manage the resource. The valuation of a natural resource, such as water and managed fisheries, can be combined with valuations of other physical or financial assets (eg. machinery or equity and investment fund shares) to provide estimates of national wealth.
