Some regional information has been withheld to avoid identification of individual production figures.
Annual production data and revenue are generated from royalties for the extraction of crown-owned minerals.
The totals and subtotals for dollar revenue excludes confidentialised values, though the totals and subtotals for quantity (tonnes) includes confidentialised values.
Gold production is taken from the annual reporting permit holders provide to New Zealand Petroleum & Minerals. The revenue is calculated by applying the average price per unit taken from the royalty returns provided to NZP&M.
Due to the limited producers for ironsands, New Zealand Petroleum & Minerals will not publish production figures for calendar year 2019 and 2020 to maintain confidentiality.
Some regional information for aggregates has been withheld to avoid identification of individual production figures.
Figures may be rounded.

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. They include bentonite, various clays, diatomite, perlite, pumice, serpentine, silica and zeolite.
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. The percentage of respondents for 2020 was 82.61% (456 respondents out of 552 quarries surveyed).
The survey response rate includes all responses received including those reporting no production, sold quarries and those who responded to advise they would not provide production data.
