The work we’re doing to update New Zealand’s nautical charts
We have an annual work programme for keeping our nautical charts up-to-date and this is shown in the table below. We make adjustments to our priorities when there are changes to an area, like new navigational lights or survey information, that need to be reflected in our charts.
Hydrographic Risk Assessment
We have carried out a risk assessment to help prioritise further survey work and chart updates.

Annual survey programme
Every year we survey parts of New Zealand’s seabed and coastline. This is called hydrographic surveying and the information we collect is used to update our nautical charts and publications.
Setting the priorities for our surveys
We use information about ship traffic and risks at sea to make sure we survey the areas that need it most, ensuring we support the needs of New Zealand’s shipping and maritime industries.
