T T Russell Fredric “In the last, probably 10–15 years, it’s branched out into more civil projects, working for larger contractors and now doing a lot of work for Waikato Regional Council.” Shifting from general agricultural drainage and contouring contracting to largescale flood protection work, J J Mangan Contracting now plays a key role in delivering infrastructure projects across the Hauraki Plains. Based in Pipiroa near Ngatea, the business provides general earthmoving services and cartage alongside civil works, including drainage construction, stopbank development, and rural and subdivision projects. Administrator Gina Cambridge says the business, owned by John Mangan, began as a small, locally focused agricultural contractor. “John started it pretty much with just himself and a couple of employees doing local paddock contouring, farm races and drainage here on the plains.” “In the last, probably 10–15 years, it’s branched out into more civil projects, working for larger contractors and now doing a lot of work for Waikato Regional Council.” That transition has been supported by pre-qualification systems and the ability to tender for larger scale projects work, supported by a strong understanding of local ground conditions. John’s familiarity with the land is a valuable asset and influences how jobs are approached, particularly in areas where drainage and soil structure play a critical role. A current example is a stopbank project along the Piako River, where the company is carrying out enabling works ahead of a wider upgrade programme by Waikato Regional Council. The project tender is for a range of fencing, culvert installations and drainage upgrade works between the township of Pipiroa, and Ngatea, along the right bank of the Piako River. “It’s a continuation of all the stopbank upgrades around the area, but this stage is about putting in the infrastructure so the next stage can go ahead.” This includes creating routes for heavy machinery and ensuring the surrounding drainage network can support the changes. “It’s putting in crossings for truck and trailer units so they can use the landward side as a haul road, along with drainage construction and boundary adjustments.” The scale of the work is significant, with several kilometres of drainage needing to be redesigned and rebuilt to suit the new layout. “We’ve had to reconfigure about 4.6 kilometres of farm drainage as part of the project.” Despite delivering projects of this size, the business itself remains relatively compact. It employs five full-time staff and brings in local subcontractors when needed, allowing it to scale up without carrying excess overhead. The company’s fleet underpins that flexibility, with excavators ranging from around 10 to 23 tonnes supported by truck and trailer units for earthmoving and cartage. Alongside civil infrastructure work, J J Mangan Contracting maintains a steady stream of maintenance and support jobs. The company has an established relationship with the Department of Conservation, including carrying out work in the Kauaeranga Valley. “There’s a lot of campgrounds and amenities up there, so we do ground maintenance, culverts, bridge crossings, river realignments, and also just grading and tidying up the gravel road surface.” Like the company’s other work, those projects are built on collaboration to achieve successful outcomes. “We’ve got a very good relationship with our contacts there, and we work together to come up with the best solutions for the issues they have.”
