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.

Find out about new and updated charts in Notices to Mariners (NtMs)

Setting our priorities

HYPLAN

The priorities for our hydrographic survey and charting work over the next 5-10 years are set out in our HYPLAN.

The priority regions in HYPLAN are the regions shown to benefit most from updated charts and navigation information. However, LINZ will review these priorities every year to determine whether they are still appropriate and needs have changed.

The results of previous surveys can be found on the LINZ Data Service.

Hydrographic Risk Assessment

The priority regions in HYPLAN are based on the results of our Hydrographic Risk Assessment. This a methodology for finding where navigation information is needed most. It bases this on navigational risk, and considers vessel traffic, hazards and the age of existing navigational information.
