The extent of indexation in the economy is much less than it was decades ago, but there are still some wage and price adjustments that are unavoidably linked to the consumers price index. The 1 October income tax reductions mean most people are already compensated for the effects of the GST increase. Given this, there is less argument for one-off CPI-indexed wage increases.
A particular message of restraint is for those parts of the economy, both public and private, that have a record of increasing prices by more than the rate of economy-wide inflation. We expect to see relative prices change in a well functioning economy.
