Referential NZD

The following table provides the inflator/deflator multiplier for calculating referential New Zealand dollars (rNZD, r$). It is based on the average annual CPI for all groups (estimated from quarter inflation index values provided by the Reserve Bank of New Zealand¹).

The formula for calculating rNZD is the following:

rNZD = nominal NZD + (nominal NZD * multiplier)
