See More. See It All. See Beneath.
We provide hydrographic surveying for construction projects, ports and harbours, rivers, lakes and other water bodies within New Zealand. Our expertise ensures you have the accurate data needed for informed decisions. Our skilled surveyors use advanced digital hydrographic equipment to measure, map and chart underwater surfaces. We can mobilise onto most vessels or use our 3m RIB for precise surveys. With a reliable baseline dataset, you can make confident decisions throughout your project. Our portable systems allow us to deploy our team quickly and efficiently to meet your needs.
Our innovative solution to map hard to reach areas of water combines traditional lead-lining techniques with modern drone technology. Our solution works in challenging conditions and dangerous to access areas providing accurate data regardless of water clarity.

“Eliot Sinclair was more than happy to take the time”
“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”
