Between February and June 2014, 6,943 people in households throughout the country took part in the survey.
The overall 2014 response rate for the NZCASS was 81%.
The Ministry of Justice managed the NZCASS with the help of a range of contracted providers.
Interviewing and offence coding activities were carried out by CBG Health Research Ltd (trading as: CBG Public Sector Surveying) on behalf of the Ministry of Justice. CBG is an independent, New Zealand-based research company.
A legal expert from Victoria University of Wellington and an expert from the NZ Police provided quality assurance advice and support as part of offence coding processes.
Statistical Insights carried out the statistical services, and experts at the University of Auckland provided quality assurance advice and support at different times throughout the project.
The questions are about:
One person from each of the randomly selected households aged 15 or might have been selected to take part in the survey. People didn’t need to have been a victim of crime to answer the questions. Participation in the survey was voluntary.
The interviewers used laptops rather than paper questionnaires.
For the last section of the questionnaire, survey participants could enter their responses directly into the computers themselves. This was because the questions were sensitive and in this way the interviewer did not see the participant’s responses.
The NZCASS is a periodic survey meaning that it is currently run every three to five years. After each survey, senior justice sector managers agree whether another survey will be conducted and when it will take place.
So far, the NZCASS has been run in 2006, 2009 and 2014.
