About the study

What is the NZAVS?

The New Zealand Attitudes and Values Study (NZAVS) is a 20-year longitudinal national study of social attitudes, personality and health outcomes of more than 60,000 New Zealanders. The study is broad-ranging and includes researchers from a number of New Zealand universities, including the University of Auckland, Victoria University of Wellington, the University of Canterbury, the University of Otago, and Massey University. The NZAVS extends our understanding of how New Zealanders' life circumstances, attitudes, values, and beliefs change over time. The study is university-based, not-for-profit and independent of political or corporate funding. The NZAVS is curated by Professor Chris Sibley.


Mission Statement

The NZAVS is a scientific study led by New Zealanders, for New Zealanders, and about New Zealanders. Broadly stated, the study aims to extend our understanding of how people and their life circumstances change over time. 

The NZAVS aims to track changes in various social psychological and health factors over a twenty year period, from 2009 to 2029. The study aims to provide information about how the personality, attitudes and values of New Zealanders may be changing over time. This is important because we currently know very little about how peoples’ opinions, values and levels of satisfaction with their lives may change gradually over time, and perhaps also change rapidly in response to current events in society. Another key aim of the study is to examine how changes in attitudes and values may relate to changes in health and wellbeing over time. Because the annual survey uses repeat respondents, it can track subtle changes in attitudes and values over time, and is becoming an important tool for researchers.

Latest NZAVS news

Wave 10 of the NZAVS Completed

The 10th (2018/2019) wave of the NZAVS is now complete and data analysis is underway. We expanded the team significantly this year and conducted a massive booster sample to recruit new participants. A total of 47,951 people completed the NZAVS questionnaire during this wave. 45% of the people who joined the NZAVS during Wave 1 back in 2009 are still in the study and also completed the Time 10 questionnaire (n = 2,964). We retained 14,049 people from our previous wave (a retention rate of 82.3% from Wave 9). Finally, a total of 29,293 people joined the NZAVS this year as part of our large-scale booster sample. We posted the booster questionnaire to a total of 325,000 people, and the response rate was 9%. Thank you to the many people who took the time to complete the questionnaire this year!


NZAVS Funding

Thank you to the Templeton Religion Trust, who funded data collection for the 10th wave of the NZAVS, and the large-scale booster sample we completed as part of Wave 10.

Thank you also to our newer participants who have joined the study as part of our more recent booster sample. It's exciting to think about what the next 8 years may bring for our research project, and what we might discover by looking at change in attitudes and values over this timeframe!

New Analysis Shows NZAVS Performing Well

A recent paper led by graduate student Nicole Satherley examined how well the NZAVS is doing at following people over time and keeping people involved in the study from year to year (congrats Nicole!). The analyses reported in this paper show that the NZAVS is healthy and performing well at keeping people involved, with detectable systematic drop out having only small effects. To be able to represent everyone reliably, the NZAVS needs as diverse and broad a range of respondents as possible. Every single person in the study is incredibly important to us, as every single response can help to increase the reliability and accuracy of our analyses. Thank you to all the participants who continue to take part in the NZAVS and who make the study possible! Read the paper online. (22 March, 2015).
