The ministry's tally of suicides is lower than the number counted by the coroners, whose data is more recent but is based on provisional suicide statistics and contains cases in which intent is yet to be established and may later be found not to be suicide.
The ministry publishes the number of suicides that have been confirmed by a coroner and those provisionally coded as suicide where there is enough information to suggest a coroner will find the cause of death to be suicide.
The coroners' provisional statistics reported 541 suicides for 2012/13; and 529 for 2013/14. Their latest tally, for 2015/16, is 579.
On hospital admissions for intentional self-harm, the ministry found there were 7267 cases in 2013 - a rate of 176.7 per 100,000 population.
The rate rose by 4.6 per cent from 2004 to 2013.
The female rate was more than twice the male rate. Among females, the highest rate was for those aged 15 to 19.
Waka Hourua, a national Māori and Pasifika suicide prevention programme, said the figures published today show the need for programmes aimed at Māori and Pasifika communities and young people.
"They indicate there is a need for targeted suicide prevention efforts to be continued and expanded.
"Waka Hourua is addressing the needs of Māori and Pasifika people by supporting solutions to the problem in the hands of the communities who are impacted by suicide. It is still in its infancy by international standards, which say that national suicide prevention strategies need to be measured over one to two decades to show the long term impact for a population.
"But the programme is showing some measurable results ... Families are telling us their initiatives are having an impact and are saving lives."
