Changes to data collection/processing
From the April 2020 FPI release onwards, Stats NZ have incorporated point of sale (checkout scanner) price data supplied directly by some supermarkets as an alternative data source. This data replaced all the items that would have previously been manually priced in-store from these supermarkets. Rather than being a point-in-time reference, the data feeding into the FPI is a weighted average for each month.

About this dataset
This table contains a selection of weighted average retail prices for the current and previous months. These weighted average retail prices were calculated from prices collected in the June 2006 month. Subsequent months' weighted average prices are then calculated by applying price index movements for the relevant items. These are not statistically accurate measures of average transaction price levels, but are reliable indicators of percentage changes in prices.
Method of collection/Data provider
Prices are surveyed by visiting retail outlets in 12 urban areas: Whangarei, Auckland, Hamilton, Tauranga, Napier-Hastings, New Plymouth, Palmerston North, Wellington, Nelson, Christchurch, Dunedin, and Invercargill.
Fresh fruit and vegetable prices are surveyed weekly, and the remaining food prices are generally surveyed between the 8th and 16th day of the month, although sometimes surveying starts and finishes earlier or later.
Food prices are collected from close to 560 outlets in the 12 pricing centres. Of these, 56 are supermarkets, 32 are greengrocers, 53 are fish shops and butchers, 68 are convenience stores (eg dairies and service stations), and 350 are restaurants (with and without bars) and takeaways.
Stats NZ collects prices from a sample of supermarkets in each of the 12 FPI pricing regions. This sample is designed to be representative of household purchases in each region.
