Salaries and wages, including overtime, rose 2% in the year to June, including a 0.4% lift in the three months to June 30.
The Labour Cost Index (LCI) for private sector salary and wage rates increased 2.1% in the year to the June 2012 quarter, a notch lower than some economists forecast, Statistics New Zealand said.
Public sector rates increased 1.6% in the same period.
The increase resulted from a 1.6% increase in central government and a 2.4% increase in local government salary and wage rates.
In the year to the June 2012 quarter, the mean increase for all surveyed salary and ordinary time wage rates that rose was 3.9%.
That was the highest increase since a 3.9% mean increase in the year to the March 2010 quarter.
Fifty-six percent of surveyed pay rates showed annual rises in the year to the June 2012 quarter.
