About Us

The farmers' favourite.


Simple  Our guiding principle. This flows through all decisions. From designing out complexity to ensure SAM’s are easy to use, look great and perform on-farm. To the best manufacturing techniques and the clever tech we incorporate along the way.

Reliable  Genuine SAM gear is built to last. Extreme reliability for you for the long-term is our goal. Design evolves based on this principle. Quick, easy parts and servicing is also prioritised for the lifetime of your SAM. 

Smart  This is where our drive to create a culture of improvement and common sense comes from. We are practical, resourceful and agile. Always looking for the very best team, materials, technology, suppliers and workmanship. 

Heart  The good stuff. Being family owned and operated gives a unique perspective. We take the best of corporate with the agility of a smaller business. We work on creating a fair workplace where everyone can have a positive influence. SAM do things a little differently.

It started with a fence

Wilf Coombridge and Johnny Alexander started making fence posts and farm gates for local farmers back in the 1940’s, after farming themselves and seeing a need. Fences evolved into hay elevators. Then after purchasing their first welder and premises in 1952, a range of steel equipment followed.

Early days were hindered by a factory flattened in the 1948 tornado that tore through Frankton, then the business was again damaged, this time by fire in 1950. The SAM name was an acronym from the names of 'Arnold & Mervin Stokes'. They were the inventors of one of the first patents the company purchased to manufacture.

Three generations later, it is a real family affair with John, Kate & Will Coombridge all part of the team. SAM Machinery now control the complete design and manufacturing process of a sought-after range of SAM Machinery. Popular throughout New Zealand and exported offshore.
