Land Information New Zealand has carried out an in-depth assessment of New Zealand waters to help us prioritise improvements to charts and navigation information.

This assessment uses vessel traffic data, as well as information about environmentally and culturally sensitive sites and hazards, like reefs, to create ‘heat maps’ which show levels of risk for navigation information.

This does not mean that the current charts are inaccurate. Rather, it will allow us to plan our work knowing which areas would benefit the most from updated charts. 

Risk Assessment Results

Next steps

We are using the results of the risk assessment to plan our survey and charting work. We are working with Maritime New Zealand, harbour masters and others to do this.

Survey work is already underway for these areas identified through the risk assessment:

  • Queen Charlotte Sound and Tory Channel
  • Kawau Bay, Approaches to Auckland
  • Tamaki Strait

Results will be used to update charts for these areas.

Other Risk Assessments

We have also used this risk assessment approach to help South West Pacific countries improve their maritime safety.
