The self-employed or business owners were twice as likely to have been impacted by work-related factors than employees of businesses, the study found.
The report is aimed at informing industry, Government, and the wider public so they can understand the risk factors and pressures that can contribute to suicide in the construction industry so that they can better respond to them, a statement said.
"To lose 300 people to suicide in our industry over 10 years is devastating. It's an employer's responsibility to provide a safe environment for their workers and this includes protecting physical and mental wellbeing. There has been huge progress in workplace health and safety over the past twenty years, but we all need to play our part in shifting attitudes towards mental health.
"We know that companies and contractors in our industry are looking for help to protect their employees' mental wellbeing. This report shines a spotlight on the pressures that exist for people working in the construction industry and it's a first step towards understanding the problem," Murray said.
The sector needs to work together to ensure mental health was protected, ranging from apprentices to small business owners and employees of large construction companies, he said.
The report showed the construction sector figures reflected the broader trends for male suicide in New Zealand. Almost all or 99 per cent of the suicide cases of people who worked in the construction industry recorded over the 10-year period were men.
The age-groups most affected were also similar to national male population figures, with 15 per cent of cases aged 20-24 and 14 per cent aged 45-49.
The report identified no single driver of construction industry suicides but found causes were complex. Yet work stress, financial strain and physical injuries were factors.
Shaun Robinson, Mental Health Foundation spokesman said the findings showed pressures on people working in the sector.
The pressures were not unique to the construction industry, but the solutions can be found by getting the industry set-up to address these challenges and improve the mental health of its people, Robinson said.
