Mortality Cover vs Disease Cover: What Farmers Need to Know

Understanding the difference between livestock mortality cover and disease & illness cover in NZ. Which do you need and how do they work together?

The Difference Between Mortality and Disease Cover

Most farmers understand they can insure their livestock against death — but many don't realise that mortality cover and disease & illness cover are often separate policies with different triggers and payouts.

Mortality Cover: What It Does

Mortality cover pays you the agreed or market value of your animal when it dies from a covered cause. Covered causes typically include:

  • Accidental death (drowning, electrocution, fire, injury)
  • Death during transit
  • Death from specified weather events (with natural disaster add-on)
  • Humane destruction required immediately following injury
  • What mortality cover does NOT typically cover:

  • Death from disease or illness (this is separate)
  • Gradual deterioration
  • Economic culling (where the animal is alive but no longer productive)
  • Disease & Illness Cover: What It Does

    Disease and illness cover compensates farmers for losses attributable to disease outbreaks and serious illness. This typically includes:

  • Emergency veterinary costs for notifiable diseases
  • Cost of government-ordered culling
  • Loss of animals from disease outbreaks
  • Some policies include production losses during disease management
  • The Mycoplasma Bovis Lesson

    The Mycoplasma bovis outbreak from 2017 onwards showed farmers exactly why disease cover matters. Farmers without explicit disease & illness cover found themselves:

  • Receiving government compensation only (which was often below full market value)
  • Unable to claim for culled animals on standard mortality-only policies
  • Facing farm debt without full recovery
  • Should You Have Both?

    For most NZ dairy and sheep/beef farmers, the answer is yes. The combination of mortality cover + disease & illness cover provides the comprehensive protection that farm operations require. A specialist adviser can structure both covers efficiently and avoid gaps in protection.
