See more, see it all, see beneath. To know what’s happening underwater we provide hydrographic surveying capabilities for small and large construction projects, ports and harbours, rivers, lakes and other water bodies within New Zealand.

When it comes to dredging, monitoring or marine construction, good data equals good decisions. Our skilled surveyors use our fleet of digital hydrographic surveying equipment and can mobilise onto most vessels or use our 3m RIB to accurately measure, map and chart underwater land surfaces.

With a reliable baseline dataset of the submerged surface from the outset, you can be confident in decisions made moving forward throughout the project.

As our systems are portable, our team can be readily deployed to most vessels.

- We approached Eliot Sinclair with some questions regarding some key ray survey points another consultant monitors. Eliot Sinclair was more than happy to take the time to resurvey the points when near site on another job. While this made a long day in the field longer for them, it saved us cost in re-establishing someone else, and helped us answer a few questions immediately. While this particular project had some scope creep that required continuing support, Eliot Sinclair remained competent and professional - yet friendly and a pleasure to work with -
