Youth suicide rates have dropped in the past year after a sharp rise last year, and coroners are now increasingly concerned about suicides by elderly people instead.
Chief Coroner Judge Neil MacLean said provisional figures showed that the suicide rate for under-20-year-olds had "dropped quite markedly" in the year to the end of June.
The drop reverses an increase from 56 suicides in the 15 to 19 age group in 2010-11 to 80 in 2011-12, up from an average of 55 a year over the previous four years.
Suicides by teenaged Maori, in particular, have fallen back after almost doubling last year, when they jumped from a four-year average of 21 a year to 37.
Judge MacLean cautioned against reading too much into these fluctuations because the graph of suicides was "a mountain range" of jagged peaks and troughs.
