About Discovery Marine
We’re a New Zealand based Hydrographic Survey company employing a diverse group of people ranging from industry leaders to recent graduates. Our team deliver hydrographic surveying services throughout New Zealand, Australia and the greater Pacific Region using a wide range of equipment and software, from our base in Mount Maunganui. Our clients typically include Governments, Science Organisations, Engineering Companies, Regional and Local Councils and Port Authorities.
WHAT TYPE OF WORK DO WE DO AT DML?
Our clients work in high-stakes coastal environments, where understanding surrounding waters is critical for ensuring safety, resilience and sustainable development. This understanding begins with knowing the local bathymetry - the depth and shape of underwater terrain, because the terrain influences how water will behave as it moves across it. As experts in the science of Hydrography, we're adept at capturing bathymetry. We also understand tides, observe currents, identify navigational hazards and provide insights into the nature of the seabed and water column above it.
HYDROGRAPHIC SURVEYING - FOR NAUTICAL CHARTING
Hydrographic surveys are required to ensure safe ship navigation and are the most complex projects we undertake, due to exacting standards and demanding operating conditions.
Surveyors leading this work must hold internationally recognised certifications and have proven experience in the science of Hydrography.

HYDROGRAPHIC SURVEYING - FOR PORT & DREDGING OPERATIONS
Port and dredging surveys are needed to ensure safe vessel operations within ports and harbours. Given the high-stakes environment, the Maritime New Zealand Good Practice Guidelines for Hydrographic Surveys in NZ Ports and Harbours, recommends that appropriately certified hydrographic surveyors undertake this work.
