Mechanical Breakdown Insurance

When buying a new car, the last thing on your mind is that it might breakdown.

But vehicles today are complex and have so many mechanical and electrical components. So we’ve designed our policies to help protect you and your budget against the cost of unexpected breakdowns.

What is MBI?

Autosure Mechanical Breakdown Insurance (MBI) covers the reasonable cost to repair the actual failure of mechanical or electrical parts as a result of a sudden and unforeseen breakdown that occurs during normal use in New Zealand, unless otherwise excluded in the policy book.


  • Comprehensive protection for petrol, diesel, hybrid and electric vehicles
  • Allowances for towing and car hire
  • 7 day / 24 hour AA Roadservice

This is a summary only – please see the policy documents for full terms, exclusions, conditions and benefits.
