About Us


CMI Springs is a New Zealand owned and operated manufacturer of traps, springs and metal components. Built on a foundation of hardwork and innovative engineering, we are proud to be New Zealand's largest spring manufacturer.

From revolutionising springs to trap design, CMI Springs worked with the Department of Conservation for a portable, lightweight and easy to use device that eradicates pest issues. After two years of observing pest behaviour, the Trapinator was developed and introduced into the marketplace. It supports the cause of returning New Zealand's bushland back to its natural state.

Possums were introduced into New Zealand to establish a fur trade, and have since then become a massive threat to native plants and wildlife. For more information regarding this cause, visit: www.doct.govt.nz.
