Quantity of gold and silver produced in New Zealand

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.
