The NZAVS began in 2009 and is curated by Professor Chris Sibley. It includes questionnaire responses from more than 70,000 New Zealand residents. The study includes researchers from many New Zealand universities, including the University of Auckland, Victoria University of Wellington, the University of Canterbury, the University of Otago, and Waikato University. Because the survey asks the same people to respond each year, it can track subtle change in attitudes and values over time, and is an important resource for researchers both in New Zealand and around the world. The NZAVS is university-based, not-for-profit and independent of political or corporate funding. https://doi.org/10.17605/OSF.IO/75SNB ## Citation Please use the following citation if you want to refer to the overall New Zealand Attitudes and Values Study itself: Sibley, C.

Broadly stated, the study aims to extend our understanding of how people and their life circumstances change over time in New Zealand. The NZAVS began in 2009 and tracks change in various social, psychological and health factors each year. By tracking change, we can understand the factors that predict how peoples’ opinions, values, mental health, wellbeing, personality, life circumstances, and so forth change gradually, and sometimes also rapidly and dramatically in response to current events. Knowing about how people are changing over time, and also across generations, can help us to see social issues that may be on the horizon, before they become serious issues. By doing so, the NZAVS aims to provide a barometer tracking the social engagement, health and wellbeing of New Zealanders and our society. ## Research Reports The NZAVS aims to provide data of use for New Zealand. We are open to requests for tailored research reports or policy briefs that can help inform understanding of the New Zealand population, how attitudes and wellbeing are changing, possible challenges facing specific populations in New Zealand, and so forth. Please contact Chris Sibley (c.sibley@auckland.ac.nz) if you would like to discuss this further. ## Participant Confidentiality Here at the NZAVS we take our participants’ confidentiality very seriously. All personal details are encrypted and stored separately from questionnaire data. Only Professor Chris Sibley and trusted research assistants working on the NZAVS in secure conditions have access to participants' contact details. Participants’ contact details are used solely for the purposes of contacting them to continue their participation in the NZAVS each year and to provide them with information and feedback about research findings from the NZAVS. ## Sample Size This table provides a brief overview of the sample size for each wave of the NZAVS.

Annual Retn. = [N retained participants from previous wave / sample size of previous wave]. Wave 1 Retn. = [N retained participants from Time 1 / Sample size of Time 1; 6518]. Total Retn. = [N retained participants / sum of all participants who have ever previously participated]. Annual Recov. = [N retained participants from earlier waves but who missed the previous wave / sum of all participants who have ever previously participated]. Date range refers to the timeframe over which data collection occurred. End dates exclude occasional very late responses to the previous wave. Time 10 data collection overlapped with Time 09 due to the start of the Time 10 booster. ## Data Availability (Statement for Publication) This is the data access statement included in publications using NZAVS data.
