Data calculation/treatment
Some respondents to the aggregate survey did not specify a value for their production. To account for this, and to allow an estimate of total value, the data provider have applied the average reported value for a given commodity to the missing values for that commodity.
Gold production is taken from the annual reporting permit holders provide to NZP&M. The value is calculated by applying the average price per unit taken from the royalty returns provided to NZP&M.

About this dataset
The production statistics feature coal, industrial minerals and metallic minerals groups. Metallic minerals produced are gold, silver and titanomagnetite ironsand. Rock, sand, and aggregate are produced for roading and construction and are vital for the development of New Zealand’s infrastructure.
A number of other industrial rocks and minerals are produced for local and export markets.
Method of collection/Data provider
New Zealand Petroleum & Minerals collects aggregate production for all quarries that have a permit for Crown-owned minerals that account for approximately half of all quarries in New Zealand.
New Zealand Petroleum & Minerals surveys all other aggregate producers but they are not statutorily required to supply their production figures.
