en-NZThe SPI covers 44 percent (by weight) of the consumers price index (CPI) basket of goods.
SPI can be factored into monetary policy decisions and potentially be used to forecast official CPI inflation.
Though this release includes more monthly data that comprises the CPI, this is not an indicative CPI measure, and no monthly headline CPI is being calculated.
It is costly to implement a monthly CPI, whether a true index or an indicative measure. The approach we have taken is utilising all the data we currently collect to quickly and cost-effectively implement changes that will be required in the future to produce a monthly CPI.
Aside from cost, another remaining constraint is the availability of data that measures monthly price changes of goods and services that are challenging to collect, such as the construction of new houses which is currently a quarterly survey to construction companies.
