Request for data models used to calculate increases in earners' levy and annually prescribed maximum figures
Lance Watson made this Official Information request to Inland Revenue Department
The request was successful.
From: Lance Watson
Dear Inland Revenue Department,
I'm aware the ACC Earner's Levies and Maximum Prescribed amounts are set out in the Accident Compensation (Earners' Levy) Regulations released semi-regularly.
However I understand these increases are calculated based on either wage growth or Consumer Price Index.
Do you have these models/calculations available for distribution? I'd appreciate a copy of as many of these as you have available, preferably in excel form so that specific formulas can be viewed.
If possible from 1 April 1992 onwards, but otherwise whatever you may have on record.
Yours faithfully,
Lance Watson
