Rolling out a new, digital navigation framework – S-100

Reducing carbon emissions, enhancing navigational safety and paving the way for autonomous shipping are just three of the benefits of a new global standard that will transform marine navigation.

Known as the S-100 standard, this digital framework blends together different data formats in real time, synthesising complex information that is critical for maritime decision-making.

As the New Zealand Hydrographic Authority (NZHA), we’re responsible for preparing our region – New Zealand, South-West Pacific and the Ross Sea area of Antarctica – for the rollout of this new Universal Hydrographic Data Model.

To help mariners prepare for this digital future, we’re introducing three new key digital products from 2026. They’re known as the S-101 – Electronic Navigational Charts; S-102 – Bathymetry; and S-104 – Water Level.

Aotearoa New Zealand. 
Our home, an island nation, isolated.
Rich with explorers, seafarers and sailors who navigated the seas to make a new life on this unique landscape.
The ocean is our lifeline and connects us.
99% of our imports and exports travel along global shipping routes.
Global events have shown us how important it is to keep New Zealand connected, and our supply chains moving.
That's why we're supporting the international rollout of the S-100 Universal Hydrographic Data Model.
This global initiative will allow mariners to connect and overlay multiple marine datasets packaged into one accessible location, unlocking the future of e-navigation and sustainable ocean management.
From the icy seas of Antarctica, all the way to our tropical island partners in the South-West Pacific.
Let's take a closer look to understand how S-100 products could revolutionise how we manage shipping on our seas.
Electronic Navigational Charts
The next generation of navigation, providing up-to-date digital charts for smarter decision-making. Download the latest updates while on board and get a real-time picture of the marine environment.
Bathymetric Surface
Water Levels
Under Keel Clearance
High resolution seabed mapping for safer, more accurate navigation and berthing.
Integrating and forecasting water level data.
Monitors the clearance between keel and seabed for safer passage.
Surface Currents
Understanding the horizontal movement of water to calculate the most efficient route. Reducing a vessel’s carbon footprint and improving fuel efficiency.
Weather Overlay
Navigational Warnings
Marine Protected Areas
Responds to updates about changing weather and sea conditions.
Broadcasting urgent hazard notifications to vessels for safer journeys.
Heightened awareness of marine protected areas, keeping vulnerable species and habitats safe.
Reduced carbon emissions. Protecting precious marine environments. Paving the way for autonomous shipping innovation.
We're helping to create a safer, smarter future for marine navigation in New Zealand and around the world.

S-100 products will be gradually phased in across the international maritime community by 2030. These timings align with those set by the International Hydrographic Organisation (IHO). It’s in response to the International Maritime Organisation (IMO) requirement for new Maritime Services for e-Navigation, and the deadline for S-100 ECDIS systems.

By adopting and implementing S-100, mariners will benefit from real-time information that unlocks opportunities to: 

  • enhance navigation safety – in open ocean and port environments 
  • improve efficiency and optimise load capacity for ships 
  • reduce carbon emissions 
  • pave the way for autonomous shipping and e-navigation 
  • use data beyond navigation.
