McMahon Services is an industry leading, privately owned industrial, construction and environmental services provider.

Established in 1990 by brothers David and Andrew McMahon, McMahon Services has grown from a humble team of 12, into an award-winning contractor across the Australia-Pacific Region. We’re now proudly located in New Zealand.

Our well-connected and innovative culture was developed early on in our company history. It has set us apart, helping us to surpass industry standards by developing a highly-skilled workforce and equipment network that is at the cutting edge of technology and best practice.

With offices in Auckland (Tāmaki Makaurau), and Wellington (Te Whanganui-a-Tara), we employ more than 950 people across New Zealand and Australia to deliver projects throughout Aotearoa, from our densely-populated city centres to our more isolated hidden gems.

McMahon Services reached New Zealand’s shores in 2018.

Our Australian branch was approached to provide asbestos remediation solutions for contaminated historical vehicles, at Auckland’s Museum of Technology and Transport (MOTAT).

The project gathered local interest and soon McMahon Services were approached by various consulting firms with an interest in servicing the growing remediation marketing utilising McMahon Services as an industry partner.

Our contributions to the local asbestos industry have already been recognised by New Zealand Demolition and Asbestos Association (NZDAA). During the 2018 Demolition and Asbestos Awards McMahon Services was presented with an award for the category ‘Asbestos or Demolition Best Practice Project’ under $1 million, for the Auckland Museum of Technology and Transport (MOTAT) project.

Our New Zealand Team

Our Auckland (Tāmaki Makaurau) operations are managed by two veterans of the asbestos, demolition and remediation industries.

John Flavel is our New Zealand National Manager, bringing over 30 years of experience in the construction, asbestos and waste remediation industries to the role. Since 1993, John has overseen the Asbestos Removal and Hazardous Waste Division of McMahon Services, delivering hazardous material abatement services for Federal and State governments and clients in the health, industrial, commercial, Defence and mining sectors, in all states and territories of Australia, and on remote island nations across the Pacific Ocean. This international experience helps him excel when dealing with Aotearoa’s diverse terrain and deconstruction needs.

Tony Woods, Construction Manager for McMahon Services’ Asbestos and Hazardous Waste Division, has relocated on a temporary basis to Auckland (Tāmaki Makaurau) to establish the office and take on a local business development role. Tony brings his extensive Australian experience in asbestos removal and abatement works to the New Zealand team.

We also employ over 40 full-time people throughout Aotearoa, supported by over 80 specialist professionals from our head office.

Project Delivery

Through our multi-disciplinary, multi-tiered approach, we have successfully delivered some of the industries’ largest and most complex construction projects, with a combined value in excess of $3.0 billion.

Our portfolio of work spans high-volume, small-scale projects to complex multi-million-dollar projects, sometimes managed over disperse geographical areas; making us experts in navigating Aotearoa’s diverse terrain. We develop long-term collaborative relationships with clients, with more than half of our work being for repeat clients across all industries.

Across all projects and service lines, all projects operate under a single McMahon Services management system.

This system is certified to the Federal Safety Commission Scheme, ISO 45001:2018 Occupational Health & Safety Management System, ISO 9001:2015 Quality Management System, and ISO 14001:2015 Environmental Management System. This ensures a consistent and streamlined project management approach.

Plant and Equipment

Our experienced in-house personnel are supported by a significant fleet of plant, equipment, workshops and warehouses, which allow us to independently perform the vast majority of our work.

We invest heavily in new technologies and boast a $140 million network of company-owned plant and equipment. Major plant items comprise of everything from dozers and excavators, to cranes and forklifts, and we use only the best equipment to service projects all over Aotearoa.
