Shyamala Nada-Raja, a senior research fellow at Otago University's Injury Prevention Research Unit, said male youth suicide had been a major concern for the past decade or so.
She said the reasons the rate was so high included the methods used, high alcohol and drug use, and violence-related issues.
Anecdotal reports suggested an increasing number of men had been contacting services for help with mental health, she said.
"That's a step in the right direction, but then they have to take another step where those young men actually get the help they need and we see an improvement in their mental health so they don't repeat these kinds of behaviour which put them at risk for suicide, and that's where we don't have the data yet to be able to comment."
Youth suicide was a complex picture, and suicide prevention experts had to continue finding ways to highlight mental health issues in young men that encouraged them to get professional help.
Dr Nada-Raja said one of the ways to encourage young men to get help was through online therapies "to try and make those more accessible for young people to use if they're feeling reluctant to make that face-to-face contact with a health professional".
She also said innovative research by the University of Auckland published last week found a computer program designed to help young people with depression had proven to be at least as effective as standard therapy.
The self-help game, SPARX, uses a 3D fantasy format to teach young people to cope with challenges and to control their moods.
Associate Health Minister Peter Dunne yesterday said that with a previously announced $62 million youth mental health project, the Government was developing a new suicide prevention action plan this year.
Mental Health Foundation chief executive Judi Clements urged all New Zealanders to think about how they could help to reduce the country's suicide rate.
