The Childcare in New Zealand Survey 2017 (CCNZ17) provides information about the use of formal and informal childcare arrangements, and the relationship between childcare, work, and study arrangements, subsidies used, and many other factors relating to childcare.
The CCNZ17 was a supplement to the Household Labour Force Survey (HLFS) in the September 2017 quarter.

A total of 3,298 households participated in the CCNZ17, consisting of 5,869 parents, 1,105 preschool children aged 0-6 years, and 2,193 schoolchildren aged 5-13. The survey was carried out from 9 July to 15 July 2017 and from 30 July to 7 October 2017.
