Ever drinkers who drank three or four standard drinks containing alcohol on a typical day when drinking.
This is the percentage of the population affected (that is, the unadjusted prevalence in the specified population).
Estimated numbers are rounded to the nearest 1,000 people.
This chart presents unadjusted results; that is the overall prevalence estimate for each survey year. Data points only appear where there is data available.
The comparison between years is only available where the same questions were asked in more than one survey year.

The estimated number of people is the value that is inferred for that population based on data collected from the survey sample. Estimated numbers are rounded to the nearest 1,000 people.

Notes:
Adjusted prevalence ratios are used to compare the results for different population subgroups. An adjusted ratio above 1 shows that the indicator is more likely, and an adjusted ratio below 1 shows the indicator is less likely, in the group of interest (e.g. Māori) than the reference group (e.g. non-Māori), after adjusting for demographic variables that could influence the association.
Kaupapa Māori consistent data analysis planning was supported by Māori and Pasifika advisors at Health New Zealand. In alignment with Kaupapa Māori research and Te Tiriti ō Waitangi principles, comparisons were made between ethnic groupings in order to identify ethnic inequities.
Equity-based ethnicity is only used for comparisons and is another form of total response. Unlike total response, which compares one ethnic group with everyone else in the sample, equity-based ethnicities compare Māori to non-Māori and non-Pacific. The same comparison group is used for Pacific peoples.

| Neighbourhood deprivation | |||
| Most deprived vs least deprived | 0.78 | ( 0.57 - 1.08 ) | Age, Sex, Ethnicity |
| Men: Most deprived vs least deprived | 0.75 | ( 0.51 - 1.11 ) | Age, Ethnicity |
| Women: Most deprived vs least deprived | 0.81 | ( 0.5 - 1.31 ) | Age, Ethnicity |
For example, an adjusted ratio of 1.50 for Māori vs non-Māori means that the indicator is 1.5 times more likely in Māori than non-Māori, after adjusting for differences in demographic variables such as sex and age.
A highlighted value indicates that the adjusted ratio is statistically significant ( p value < .05).

Notes:
Ever drinkers who drank three or four standard drinks containing alcohol on a typical day when drinking.
A standard drink is one can or small bottle of beer, one small glass of wine, or one shot of spirits.
Lower response rates in 2018 than in 2016 and 2020 among young (15 to 24 years) male Māori, young male NZ European/Other, young female Asian, and older (55+ years) male Asian respondents mean that comparisons of 2018 data with 2016 and 2020 should be made with caution. We recommend focusing on longer-term trends where possible.
Interviewing for the 2020 Health and Lifestyles Survey was delayed for five months due to the COVID-19 lockdown. Interviewing was then suspended twice in the Auckland region in response to the alert level being raised to level 3. At all other times, interviewing 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 the impacts of these delays and the pandemic response.
