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) |
