Māori population and the indoor environment

Indicator	Key findings
Maternal smoking	Smoking rates among Māori mothers have declined from 32.3% in 2009 to 19.5% in 2021.
Second-hand smoke exposure	While Māori were more likely to be exposed to second-hand smoke than non-Māori, rates have decreased. The rate of second-hand smoke exposure in the home for Māori children decreased from 9.2% in 2012/13 to 6.1% in 2015/16.
Asthma	The rate of asthma hospitalisations increased steadily for all ethnic groups from 2002 to 2018. Māori children aged 2-14 years had the highest prevalence of medicated asthma in 2020/21 (16.6%). Māori children were 1.6 times as likely to have medicated asthma as non-Māori after adjusting for age and sex.
Sudden unexpected death in infancy (SUDI)	In 2014–18, SUDI rates were five times higher among Māori and Pacific babies than European/Other babies.

Indicator	Key findings
Vulnerability to climate change	Māori are likely to be more exposed to a changing climate given that many Māori live in the north and east of New Zealand where hot days are projected to increase. The Māori economy is heavily reliant on climate-sensitive primary industries.

Indicator	Key findings
Road traffic injury deaths and hospitalisations	Hospitalisation rates for road traffic injuries for Māori increased from 2014 to 2018. For 2009–2018, Māori had significantly higher mortality rates for vehicle occupant, motorcyclist and pedestrian injuries than non-Māori.
