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.

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 those shown to benefit most from updated charts and navigation information. First published in 2017, we reviewed these priorities in 2019 and 2020 to reflect areas that have been completed.

Hydrographic Risk Assessments

The priority regions in HYPLAN are based on the results of our Hydrographic Risk Assessment for New Zealand and the Sub-Antarctic Islands. The risk assessment takes into account ship traffic, hazards and the age of existing navigational information to determine the level and location of navigational related risk.
