What does the data tell us?
When looking at suicide statistics, it’s important to consider the difference between rates and numbers. Numbers are the number of individuals who have died by suicide, while rates show how many suicides occurred per every 100,000 people in the population. Looking at the rates over time will show whether or if the overall situation/trend has changed. It may be that the number of people who die by suicide increases but because the overall population has increased, the suicide rate remains unchanged or decreases. It’s important to consider suicide data over a number of years rather than measuring trends over a single year. Behind these statistics are lives lost, families devastated, and communities in pain.
The figures below are taken from the provisional data by the Chief Coroner, the Ministry of Health, and other sources of information:
- 538 people died by suspected suicide in the 2021/22 financial year (from July 2021 to June 2022), less than the 607 reported for 2020/21 and 628 reported in 2019/20.
- Males are more than twice as likely to die by suicide than females.

Ministry of Health suicide trend data shows that between 1996 and 2016:
- There was a 20% decrease in the national suicide rate, although this was not equal across all populations.
- Suicide rates for Māori fluctuated but were significantly higher than for non-Māori for most of this time.
- For much of this period, suicide rates for Māori tended to be highest for males, those aged 15–44 years, and those living in more deprived areas.
- For Pasifika, the rate of suicide for those aged 15–24 years was significantly higher than for those in the older age groups.
- The rate of suicide for males decreased significantly (26%), from 22.9 per 100,000 males in 1996 to 17.0 per 100,000 males in 2016. During the same time, the rate for females didn't change significantly.
- Differences in the rates of suicide between those living in rural and urban areas have become smaller. The most notable change was for males in rural areas. The rate for this group reduced from a peak of 26.6 per 100,000 in 2010, to a rate at or below 20.0 per 100,000 since 2012.
- The age groups with the three highest suicide rates in 2019/2020 are 25-29, 30-34 and 80-84.
Youth suicide data
New Zealand’s youth suicide rate for adolescents aged 15-19 years was reported to be the highest of 41 OECD/EU countries (based on data from 2010).
The Youth19 survey revealed that:
- 23% had significant depressive symptoms, up from 13% in 2012.
- 6.2% of young people had attempted suicide, and the rate for females (7.3%) was higher than males (5.0%). Serious thoughts of suicide and attempted suicide occurred more often in areas of high deprivation. The rate for males had increased since 2012.
- 19% had difficulty getting help for their emotional concerns.
- 53% of same- or multiple-sex attracted students reported significant depressive symptoms. Half (50%) of this group reported that they had self-harmed in the past year.
- 13% same- or multiple-sex attracted students reported they had attempted suicide in the past year.
The 15th data report of the Child and Youth Mortality Review Committee showed that during the period 2015–19:
- 2,666 children and young people aged 28 days to 24 years died.
- Suicide was the third leading category of death with 24.6%
- By individual cause of death over the five years from 2015 to 2019, the top cause of deaths were from suicide (655)
- The leading category of death changes with age. Medical conditions were the most common cause of death in children aged younger than 15 years, suicide was the most common category in those aged 15–19 years and injury was the main cause in those aged 20–24 years.
