This top line summary provides a high-level overview of results from the 2020 Health and Lifestyles Survey (HLS). The HLS monitors short, medium, and long-term societal changes in attitudes, knowledge, and behaviours related to mental health and wellbeing, tobacco use, vaping, gambling, nutrition, alcohol, and sun exposure. The HLS also tracks changes in views about the social desirability and acceptability of various strategies to minimise harm from these risk factors and promote wellbeing. This summary focuses on the prevalence of these risk factors, exposure to harm, and strategies to minimise harm.
The HLS is a nationwide in-home face-to-face survey of New Zealand residents aged 16 years and over. This survey has been carried out every two years since 2008, with the latest survey completed between 28 September 2020 and 4 May 2021 by 3,089 adults. Based on prioritised ethnic group categorisation, there were 992 Māori, 412 Pacific peoples, 225 Asian, and 1,460 people of NZ European/Other ethnicity.
Detailed information about the survey approach and sample profile can be found in the 2020 HLS Methodology Report.
HLS fieldwork was carried out by CBG Research. The write-up was provided by NielsenIQ.
Impact of COVID-19
Interviews for the 2020 Health and Lifestyles Survey were delayed for five months due to the COVID-19 lockdown. Interviews were then suspended twice in the Auckland region in response to the alert level rise to Level 3. At all other times, interviews took place at alert levels 1 and 2 with additional COVID-19 precautions in place. It is unclear what impact the delays to the survey and the pandemic response have had on the data. No adjustments have been made to account for potential impacts of these delays and the pandemic response.

Results presented here include “don’t know” and “refused” responses in the base.
- Current mental distress
- Current mental distress was measured using the Kessler Psychological Distress Scale (K10), a 10-item questionnaire (questions M1-M10) that is used in clinical practice to screen for distress. Scores range from 10-50 and have been grouped for analysis into no to low current mental or psychological distress (10-15), moderate (16-21), and high to very high (22-50).
- Current smoker
- ‘Current smoker’ refers to someone who smokes tobacco at least once a month or more often.
- ‘Vaper’ refers to someone who vapes at least once a month or more often.
- Problem Gambling Severity Index (PGSI)
- The PGSI is a nine-item scale (questions G23-G31) that is used to assess people’s experiences of gambling-related harm in the last 12 months. Scores range from 0 to 27 and have been grouped for analysis into non-problem gamblers (0), low-risk gamblers (1-2), and moderate to problem gamblers (3 and above).
- The AUDIT-C is a three question (questions F14-F16) assessment tool that can be used to provide a quick assessment of how much and how often an individual is drinking alcohol. Scores range from 0 to 12 and have been grouped for analysis into non-hazardous drinkers (male 0-3, female 0-2) and hazardous drinkers (male 4-12, female 3-12). Generally the higher the score, the more likely it is that the respondents’ drinking is affecting their safety.
Accessing our microdata
The Authors acknowledge that the language and terms that support the design of the questionnaire are ever-changing and may no longer be considered appropriate. For this article, the original language and terms in the questionnaire have been used. It would not be right to use the new language when referring to the question, as it would not accurately reflect the choices/responses made by respondents when they completed the survey. One example of this is the reference to “mental illness” despite the recommended term now being “mental distress.”
