What We Do
At March Cato, we love a challenge, whether it’s deep, large diameter, lots of interfaces, complex ground conditions or difficult access – whatever the challenges are, this is what we are all about. Over the last 25 years, we have tackled some of Auckland’s most difficult and high profile projects and have grown an enviable reputation with our fantastic clients for the safe delivery of these challenging works. We specialise in the following:

Our trenching crews are supported by a fleet of trucks, loaders, and transporters as well as our own, in-house traffic management team, who are experienced in dealing with the unique conditions and environments that we operate in.
