What Discovery Marine does

Discovery Marine Ltd (DML Surveys) is a New Zealand-headquartered hydrographic surveying firm founded in 1997, delivering bathymetric, seabed characterization, and underwater imaging services to government agencies, port authorities, regional councils, engineering consultancies, and scientific research organizations. The company operates from Mount Maunganui with a wholly-owned Australian subsidiary (Discovery Marine Australia Ltd, DMAL) and has executed projects across New Zealand, Australia, and the Pacific region including Samoa and the Federated States of Micronesia. Its core service lines span nautical charting surveys (LINZ and HIPP panel work), port and dredging surveys, erosion and sedimentation monitoring, dam and reservoir infrastructure surveys, backscatter and water column data acquisition, habitat mapping, and remote-location surveys for international development.

The company's technical platform is built around multibeam echo sounders (MBES), single beam echo sounders (SBES), mobile laser scanning (MLS), side scan sonar, acoustic Doppler current profilers (ADCP), remotely operated surface vessels (USV KOURA), and underwater photography/video systems, with data processed using QPS Qinsy and Qimera software. The firm holds sector-critical certifications including IHO Cat A surveyor status, CPHS Level 1 panel provider status, Maritime Operator Safety System (MOSS) certification, Site Safe Gold accreditation, and impac PREQUAL 5-star rating, making it one of only two LINZ-approved panel providers for nautical charting in New Zealand and the only NZ-owned firm approved for Royal Australian Navy hydrographic work.

Discovery Marine generates revenue through project-based professional services contracts, delivering tailored deliverables (survey plans, cross-sections, 2D/3D imagery, GeoTIFF rasters, gridded bathymetry surfaces, point clouds, ESRI/DXF survey data, and side scan mosaics) to clients. The company is majority-owned by Seaworks, a strategic marine-sector operating company, following a 2021 transaction that also installed a new leadership team (Declan Stubbing as CEO, Kevin Smith as CCO/Director). Customer relationships are long-tenured — Port of Tauranga has been a client since 2005 — and the firm has completed 919+ projects with 164+ combined years of field experience across its roughly 17-person team. Sales occur primarily through panel provider arrangements, direct enterprise contracts, and partnerships with engineering firms (e.g., Tonkin & Taylor) for international development work.

Broad incumbents

• Ocean Infinity: Marine autonomous systems and survey operator offering MBES, geophysical and seabed mapping services at scale; competes for the same offshore and charting tenders as DML while leveraging uncrewed surface vessels.
• TGS: Global energy-data and marine acquisition firm operating hydrographic and geophysical spreads; competes for marine survey tenders and shares multibeam/seabed-imaging capabilities with DML.
• Fugro: Global geotechnical and hydrographic survey giant; Fugro competes with DML on large-scale bathymetric, geophysical and charting campaigns and operates the vessel fleets that dominate offshore hydrographic tenders worldwide.
• PGS (Petroleum Geo-Services): Marine geophysical acquisition and multi-client data company using seismic and acoustic methods; shares the underlying acoustic and seabed-mapping technology stack and client base as DML.
• UTEC (Acteon): Acteon-owned subsea survey and positioning services provider; competes on offshore hydrographic positioning, pipeline route survey, and integrated geophysical campaigns analogous to DML's offerings.
• Reach Subsea: Norwegian offshore survey and subsea services firm offering hydrographic, geophysical and ROV-based inspection; comparable in vessel-deployed hydrographic and geophysical survey delivery model.

Direct peers

• Exail (formerly iXblue): Provides hydrographic positioning, INS, USV and survey services used alongside multibeam systems; overlaps DML most directly on integrated USV-based hydrographic campaigns in shallow and confined waters.

Emerging players

• NIWA (National Institute of Water and Atmospheric Research): Crown-research institute conducting marine science and hydrographic surveys in New Zealand waters; collaborates with DML on Queen Charlotte Sound-style joint hydrographic-and-ecology campaigns and could compete for niche science survey work.
