Labour Market Statistics (Income): June 2017 quarter

##External data influencers We collected data in this release in the June 2017 quarter (9 April to 8 July 2017). Changes in income may be influenced by one-off events. Events that could have influenced the June 2017 quarter data are: the increase in the adult minimum wage from $15.25 to $15.75 (effective from 1 April 2017) increases in New Zealand Superannuation rates of 1.4 percent (effective from 1 April 2017). increase in benefit rates of 1.1 percent (effective from 1 April 2017). The recent government deal to lift pay for aged care workers came into effect on 1 July 2017, so is not reflected in the June 2017 quarter figures. ##Response Rate As the Labour Market Statistics (Income) content is collected as part of the Household Labour Force Survey (HLFS), the same target response rate and target achieved sample rate apply. The target response rate for the HLFS is 90 percent and target achieved sample rate is 76 percent. The response rate for the June 2017 quarter was 78.0 percent and the achieved sample rate was 70.3 percent. See New quality measures for the Household Labour Force Survey for more information on the sample rate and response rates. ##Sampling errors The table below summarises the main relative sampling errors for the June 2016 and June 2017 quarters, by income source.
