Commodity review

We are continuing our rolling review of the business price indexes. The review has two objectives: to maintain the relevance of these indexes and to collect commodity data for use in the national accounts. We are surveying a sample of economically significant enterprises operating in New Zealand, to collect information on their supply and use of goods and services (commodities). We use this commodity information (by industry) to update lower-level weights for the business price indexes. We use these indexes as deflators in producing a chain-volume measure of GDP.

Exchange rates

When calculating the PPI and CGPI, we generally use prices collected on the 15th day of the middle month in the quarter to represent the entire quarter. When these prices are collected in foreign currencies, they are converted to NZ dollars using the exchange rate at the mid-point of the quarter.
