Data Collection Period
A randomly-selected, cross-sectional sample of 4,443 New Zealand adults completed the interviewer-administered Active NZ Survey. Participants were recruited throughout New Zealand. To account for seasonal differences, the sample was stratified by each month of the survey year (March 2007 to March 2008).
The sampling methodology was designed to enable SPARC to provide high-level information about sport, recreation and physical activity levels at a regional level, based on the geographical areas serviced by New Zealand’s 17 regional sports trusts (RSTs).
At least 200 participants were interviewed in each region, with the exception of Gisborne, where the interview target was 100 (fewer participants were targeted because of the geographical spread of the Gisborne population).
The sample methodology included a main sample and three ethnic booster samples (Maori, Pacific Island, Maori/Pacific Island/ Asian) and a geographical booster sample (urban booster areas).
To ensure respondents were selected at random, interviewers listed each person in the household over 16 years of age and selected the one who most recently celebrated their birthday.
An overall response rate of 61 percent was achieved. The data have been weighted to be representative of the New Zealand adult population.
