About Uniweld

Uniweld is a family owned business that has been operating since the early 1950’s. The roots of the business flourished in the early days with a strong focus on cars and numerous forms of motorsport together with a wide skill set to offer the commercial vehicle sector. This great foundation has seen the business grow and diversify over the last 65 years and Uniweld has now become a leader in it’s field.

In 2015 the Uniweld Group purchased Amega Wire which has bought with it a far more diverse range of engineering skills to offer. In addition to a huge knowledge base on towbars, mufflers, and exhaust systems, the company is now well positioned to offer a wide range of general engineering services , sheet metal, and wire products. This takes Uniweld into the manufacturing sector with a very strong foundation to work from.

In 2017 the Uniweld Group was fortunate to acquire C J Williamson which has been manufacturing health care equipment for over 100 years. With fabrication and manufacturing already being a huge part of what Uniweld does, the fit for the CJW company was perfect. The Uniweld Group will now look to continue the specialised manufacturing, pioneered by C J Williamson, for another 100 years…..

Owner Grant O’Neill has decades of experience to offer. This experience brings with it a wealth of welding and engineering knowledge – exactly the right mix to advise clients on exhaust and towbar requirements and in addition brings Uniweld into the forefront of local engineering and manufacturing in Christchurch.

Grant is extremely enthusiastic about Uniweld and is fully qualified to advise you on all aspects of towbars, exhaust, mufflers, and general engineering. The business is well supported by interested and knowledgeable staff  – certified welders and years of experience all round make for superior service.

In more recent years Uniweld has acquired the distribution rights for Rhino Rack products and offers a full range of roof racks and every accessory imaginable. With Eftpos facilities available mufflers and chrome exhaust tips can be purchased over the counter as can gaskets, resonators, and a wide variety of products – and yes we manufacture and stock netball hoops.
