Specialist Engineering Services, Contractors & Products

Providing Exceptional Service Across Nelson Tasman Since 1972


Committed to exceptional engineering since 1972

Delivering exceptional innovation and customer care since 1972

We’ve been in the business of exceptional engineering for 48 years.

We cut our teeth servicing the maintenance needs of the fishing industry – the ideal sector to cement the importance of delivering on time and on budget. Today we support diverse industries in multiple ways, however one thing remains true – happy customers are at the heart of all we do.

What we do is flexible, scalable and entirely built around customer needs and budgets. Our key services include maintenance, fabrication, machined parts and certified pipe welding. Our key products include stillage racking, fall protection and guarding. And having an inhouse design team means that we’re always at the cutting edge of solutions for customers.

We have long term working relationships with many of New Zealand’s iconic companies. Be it timber, manufacturing, infrastructure, marine, dairy, mining, cement or something else altogether our years in the trade have given us a wealth of expertise.

We know that how we do things matters just as much as what we do.

  • QUALITY We are one of the few NZ engineering firms certified under the international quality standard AS/NZS ISO 9001:2016. We live and breathe this every day using our Kernohan Exceptional Engineers System (KEES).
  • SAFETY Our customers routinely tell us that how we approach health & safety makes us their preferred engineer of choice. Our non-negotiable commitment to working safe is backed up by years of investment in training and systems.
  • ENVIRONMENT We want to do our bit for the planet. As at 2019 our business has been certified as carbon neutral, a commitment that we aspire to maintain every year.
  • RISK We do our best to protect customer assets, with extensive insurance cover that includes professional indemnity, contract works and products liability.
  • COMMUNITY As a cornerstone sponsor of the Nelson Tasman Chamber of Commerce we’re investing in the success of all businesses in our region.

Our head office and workshop facilities are based at the centrally located port in Nelson.

We have three specialist workshops:

A 1,826m2 space dedicated to our fabrication and project services. It has an outside area for overflow, and is adjacent to a slipway.

A 448m2 workshop dedicated to our machine shop services.

A 228m2 workshop focused on the creation and manufacture of products.

Nelson’s our home turf, however for most services we can come to you. From the top of the North Island to the bottom of the South we have a proven ability to mobilise people and plant to customer sites. From containerised workshops to sourcing cost effective accommodation we custom build practical, affordable solutions.

We’d love to share our enthusiasm for exceptional engineering with you
