Prototyping
Our prototyping services are integral to any custom design project. We combine our design and manufacturing expertise to design, test and evaluate a prototype accurately, efficiently and cost-effectively.
We undertake any electro-mechanical, fabrication or structural project using state-of-the art machinery and processes to engineer precision products.
custom fabrication design
We focus on all aspects of development through the design and fabrication process from conception to completion. As a workshop that uniquely combines a full custom design, build and installation service we see increased demand for this comprehensive capability.
manufacturing design
We have proven experience in the design and manufacture of cost-effective, reliable and quality products. No manufacturing job is too big or too small as we have the capacity to handle a variety of projects.
We achieve this with specialist capabilities such as 2D and 3D CAD, mechanical and electrical engineers, PLC systems and controls,
integrated CAM, design for controls and electrical systems.
general engineering
Our workshop offers the full spectrum of general engineering needs from MIG/TIG/ARC welding to stainless steel and aluminium welding, steel cutting and processing to machining and boring. We also have our own electrical workshop in-house.
our past
since 1945

J & D McLennan Ltd was established in Wellington in 1945 after brothers James and Duncan McLennan returned from serving in the armed forces during World War II. The company started life as a general engineering and maintenance business servicing the local community and operating out of old horse stables in Petone.
J & D McLennan is now one of the largest and most complete engineering shops in the Wellington area. Constant investment in production machinery and techniques have extended our capabilities as general engineers with a strong mechanical background to offer a wide range of design and fabrication solutions.
