Real price series have been constructed using Stats NZ's Consumers Price Index series - CPIQ:SE9A (for retail and residential prices), and Producers Price Index (Input) series - PPIQ:SN9 (for commercial, industrial and wholesale prices).
Data calculation/treatment
Prices are presented inclusive of all applicable taxes and levies. Industrial and commercial prices exclude Goods and Services Tax (GST) as these sectors can generally reclaim the GST component. Wholesale prices are assumed to relate to the commercial sector so exclude GST. Residential customers generally cannot reclaim GST therefore residential prices include the GST component.
