Common questions

Frequently Asked

Do you offer mobile engineering on the Hauraki Plains?+
Yes. We cover the full Hauraki Plains and surrounding Waikato with our mobile engineering service — bringing the workshop to your farm or worksite for repairs, installations and fabrication with minimal downtime. We regularly work in Ngatea, Paeroa, Thames and Waihi.
Are you LT400 certified?+
Yes. Our qualified heavy vehicle engineers hold LT400 certification for drawbeam and drawbar repairs. This means your truck or trailer can be certified back to full compliance at our workshop — no need to go elsewhere for sign-off.
What vehicles and machinery can you fabricate for?+
Tippers, tow trucks, utes, bulldozers, trailers, farm machinery and more. We handle new builds, custom repairs, drawbeams and drawbars. If you have a specific vehicle or application in mind, call us and we'll scope it out.
Do you sell engineering supplies?+
Yes — fasteners, hydraulic hoses, fittings, valves, nuts and bolts. We keep a practical range in stock at the Netherton workshop. Call ahead or come in to see what's available.
What are your workshop hours?+
Monday to Friday, 7:30 AM to 4:00 PM. For urgent after-hours matters, call 021 033 9882 and we'll do our best to assist.
How do I get a quote from Cole Engineering?+
Call 07 862 3861, email smythesengineering@gmail.com, or drop by 1183 Hauraki Road, Netherton. For complex fabrication or structural jobs we may need to visit your site before we can quote accurately.
Do you repair agricultural and farm hydraulics?+
Absolutely. Hydraulic work is core to what we do — hoses, rams, cylinders and full system repairs on farm machinery, trucks and other equipment. We also stock hydraulic hoses and fittings for quick on-site fixes.
Where is Cole Engineering based?+
1183 Hauraki Road, Netherton 3671 — in the heart of the Hauraki Plains, Waikato, New Zealand. We're the engineering workshop locals have trusted for over 20 years.
What is LT400 certification and why does it matter?+
LT400 is a New Zealand Transport Agency (NZTA) certification category for low-volume vehicle structural repairs — specifically covering drawbeams and drawbars on heavy vehicles. Having a LT400 certified engineer means your transport can be signed off for road compliance at our workshop, saving time and cost compared to going through a full engineering authority.
Can you weld and fabricate structural steel on-farm?+
Yes. Our mobile engineering unit is equipped for structural steel welding and fabrication on-site. Whether it's a farm building frame, equipment mount or custom bracket, we can come to you across the Hauraki Plains and wider Waikato.
Is Cole Engineering a new business?+
The workshop has more than 20 years of history in Netherton. Under new ownership since December 2024, Cole Engineering Ltd continues that tradition with LT400 certified engineers, qualified NZ welders and a focus on practical solutions for rural New Zealand.
Do you do custom trailer fabrication near Thames or Paeroa?+
Yes. Cole Engineering builds and repairs custom trailers for clients across the Hauraki region including Thames, Paeroa, Ngatea and Waihi. We also carry out drawbeam and drawbar modifications and LT400 certified repairs for heavy transport compliance.
