The Prostate Cancer Foundation says it seems many rural men manage their farms better than their own health.
The foundation says 3000 men are diagnosed with prostate cancer each year, with 600 dying from the disease.
It believes that 200 to 300 of those deaths could have been prevented with early intervention.
Foundation representatives have been at the South Island Field Days urging men to get checked.
The organisation's vice-chair Ants Parder says men appear to be less concerned than women about health matters.
He says farmers need to manage their own health in the same way they would their farm animals or equipment rather than making excuses for not getting check-ups.
