About Us

Cranston Engineering specialise in CNC machining. Owners Bevan and Katrina Clarke have developed a team of expert machinists who proudly deliver outstanding service.

We are very particular. You expect your components to be machined to a very high level of precision. To do this, we have invested in advanced CNC mills, CNC lathes, and robots. Our machinists are expertly trained and committed to getting it right.

Our design team is very careful. The setup is critical, so we liaise with you to ensure the drawings are correct and the result is what you want. We are serious about getting it right first time, every time. That’s why our clients return. We don’t waste your time or ours.

Our multinational clients are very demanding, and we deliver. Our tow balls are very popular because we make them the same, every time.

Our clients really appreciate receiving outstanding service. If you need something machined the same, in small runs or by the thousands – get in touch and we’ll make it happen.

CNC Manufacturing

What we do

As CNC machinists, Cranston’s machines components for products that our clients sell throughout New Zealand and around the world. Tow balls are an example.

We take your designs, check them and, if required, improve them, machine the part, pack and deliver. In some cases, it is more cost effective to do large runs which are stored as stock for you to access when needed.

Small runs or thousands, are treated with the same care and precision. Right, first time, is the key to efficiency. Our technology and expertise allow us to create whatever is needed.
