Review of scope and purpose of the producers price index

This report reviews the purpose of the producers price index (PPI) and proposes the current purpose be confirmed – to measure producer output and input inflation within the framework of the System of National Accounts.

Statistics NZ has produced the PPI in essentially its current form for the past 35 years. Over this time there have been numerous re-weights and re-bases of the index and we have adopted new industry classifications. The index has also adopted a ‘building block’ approach, with lower-level commodity indexes feeding into higher-level industry indexes, which provides greater flexibility for index maintenance. However, the underlying conceptual basis and structure have remained the same.

We are seeking feedback from data users on the proposal to confirm the PPI's purpose, and other related topics, including:

  • output and input industry indexes
  • weighting concepts
  • scope of transactions.

You are invited to make a submission to Statistics NZ, by 5pm, 25 November 2013.

Please email your submission to info@stats.govt.nz or ring Henry Minish, Meighan Ragg, or James Griffin (04 931 4600 or 0508 525 525). We are happy to meet users who want to discuss the topics.
