Abstract

AIMS: It is timely to examine changes in male and female suicide rates across the age range in New Zealand, comparing them to some of the changes recorded in Australia.

METHOD: Data regarding suicide and population figures in New Zealand and Australia were obtained. The suicide rates of different age-groups in the two countries were calculated and compared. Data concerning 'open verdicts' were also obtained.

RESULTS: The age patterns of suicide rates in New Zealand and Australia have changed markedly and similarly. Suicide rates of New Zealand males in their twenties increased threefold between the 1960s and 1990s, with a fall since then. Nevertheless, the 2009-13 youth suicide rates in New Zealand were double the corresponding rates in Australia. Since 1979-88 a decrease in suicide rates of men and women aged 60-79 has been even greater than in Australia. The Māori suicide rate is high in young men but almost zero in old age.

CONCLUSIONS: The persistently high suicide rate of New Zealand youths (Māori much more than non-Māori) remains of concern. The rate is equally high among indigenous young Australians. There has been a welcome decrease in late-life suicide rates in New Zealand and Australia.
