This index enables you to identify the bathymetric data held and used by LINZ on its SW Pacific nautical charts. Some of our data holdings date back to 1898. The polygons comprising the index show the extent of the survey datasets. The attributes attached to each polygon will enable you to view, amongst other attributes, the age and quality of the bathymetric data.

Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset.

The bathymetric data is not downloadable from the LINZ Data Service. Datasets prior to the year 2000 are predominantly available only as georeferenced TIFF images of the original hard copy sounding sheets. Data post-2000 is often available as both georeferenced TIFF images and as digital data files (vector data in plain text format).

Requests for the bathymetric data should be sent to customersupport@linz.govt.nz with “Hydro Bathy Data” in the subject line. Requests must, as a minimum, specify the id, chart_no and serial_no as shown in the attributes attached to each polygon representing the datasets of interest.

The provision of bathymetric data may be subject to some delay as LINZ confirms with the data owner that they are happy for their data to be released. The owner may attach conditions to the release of their data.

This dataset provides the boundary of New Zealand’s continental shelf, which is the area of seabed around a large land mass where the sea is relatively shallow compared with the open ocean.

The continental shelf is the seabed and subsoil of the submarine areas that extend beyond the territorial sea of a coastal state throughout the natural prolongation of its land territory to the outer edge of the continental margin.

In New Zealand’s case, the continental margin extends beyond the Exclusive Economic Zone in many places and the outer limits have been established on the basis of the recommendations of the United Nations Commission on the Limits of the Continental Shelf. Under UNCLOS, New Zealand exercises sovereign rights over the continental shelf for the purpose of exploring it and exploiting its natural resources.

Note: The boundary includes, where applicable, the delimitation of the boundaries of the continental shelf with Australia under the treaty of 25 July 2004. The delimitation of the maritime boundaries in the north with Fiji, Tonga and possibly France in respect of New Caledonia, have yet to be settled by treaty.
