One in five construction workers in New Zealand is estimated to engage in hazardous drinking — a rate higher than the general population’s already concerning one in six. The tradie who drinks hard after working hard is a cultural cliché, but behind the stereotype is a genuine and serious issue that the industry has been slow to address.
Alcohol is New Zealand’s most widely used drug, and its harms are routinely minimised. The long-term physical consequences — liver damage, heart disease, increased cancer risk — are well-documented. So are the mental health impacts, including elevated rates of depression and anxiety, and the increased risk of suicidal ideation among people with alcohol dependency. In a sector already dealing with elevated rates of work-related stress and fatigue, alcohol dependency compounds the problem significantly.
Why Construction Is High-Risk
The conditions of construction work create particular vulnerability. Physical labour is hard on the body, and alcohol is a culturally normalised pain reliever. Work is often seasonal or project-based, creating income uncertainty that generates stress. The industry’s culture has historically been one where showing vulnerability is discouraged and where drinking together is a primary form of social bonding.
For business owners and sole traders in the trades, isolation adds another layer. Running your own business means carrying problems alone — client disputes, cash flow pressure, difficult staff — without the support structures that exist in larger organisations.
What Hazardous Drinking Looks Like
Hazardous drinking doesn’t require being an alcoholic. It means regularly drinking at levels that increase health and safety risk. For men, that threshold — set by the Ministry of Health — is more than 15 standard drinks per week. Four or more drinks on a single occasion also constitutes hazardous use. Given the culture in some parts of the trades, Friday afternoon drinks that continue into the evening can regularly cross this threshold.
What Employers and Mates Can Do
The most effective interventions are relational, not programmatic. Noticing a change in a colleague or employee — increased absences, unusual behaviour, visible deterioration — and raising it in a direct but caring way is something every person in the industry can do.
Employers have both a wellbeing duty and a safety obligation. An impaired worker is a risk to themselves and everyone around them. Drug and alcohol policies need to be clear, fair, and consistently applied — not just on paper but in practice.
Resources available to the construction sector include MATES in Construction’s helpline (0800 111 315), the Te Ara Oranga alcohol and other drug treatment service, and the free Alcohol Drug Helpline at 0800 787 797. The first step is removing the stigma from seeking help — and that starts with leadership at every level of the industry.
