Heron’s first dredgers were small cutter suction dredges, employed on the Whangamarino and Waikato Rivers in the early 1970s. This was followed by de-sludging works for Tasman Pulp & Paper and New Zealand Steel; river and harbour pipeline crossings; hydro desedimentation works; dredging for boat marinas; and harbour dredging for Port Companies.
Today, after 50 years of operation, Heron owns, operates and maintains an extensive fleet of plant and equipment.
The Company owns a five acre site with fully equipped workshops at Papakura south of Auckland, and employs four permanent engineers for the fabrication and maintenance of equipment. An additional waterfront property with floating jetty is leased from the Port of Tauranga at Sulphur Point where two engineers are employed mainly for barge and floating plant maintenance.
