This compares with 36.4% in the second quarter of 2012.
Today's statistics also includes a detailed breakdown of the average usual hours worked every week.
Of the 14 economic sectors, the Agriculture, forestry and fishing sector had the highest average at 50.4 hours a week in the second quarter of this year, while the Education sector had the lowest at 30.1 hours per week.
