- 35% of Māori adults were current smokers, down from 42% in 2006/07.
- 24% of Pacific adults were current smokers (not a significant change from previous years – 27% in 2006/07).
- Current smoking rates are declining for younger adults, but there has been no significant change for adults aged 35 years and over since 2011/12.
- Adults living in the most socio-economically deprived areas were more than 3 times as likely to be current smokers as people living in the least deprived areas, after adjusting for age, sex and ethnic differences.

- Hazardous drinking rates were higher in men (27%) than women (12%).
- Rates of hazardous drinking were highest in youth aged 18–24 years (33%).
- Despite there being more non-drinkers in the most socioeconomically deprived areas, adult drinkers in the most deprived areas were 1.7 times more likely to be hazardous drinkers than adult drinkers in the least deprived areas, after adjusting for age, sex and ethnic differences.
- Nearly 100,000 children aged 2–14 years (12.3%) were obese. The child obesity rate has not changed significantly since 2011/12 (when it was 10.7%), although it has increased since 2006/07 (8.4%).

Access to health care
Unmet need for GPs due to cost
- 1 in 7 adults (14%) reported not visiting a GP due to cost in the past year, which is not significantly different from 2006/07.

Rates of unmet need for GP services due to cost were low for children aged 6–12 years (2.7%). This represented a decrease from the 2015/16 rate (5.8% for children aged 6–12 years).
