This index enables you to identify the georeferenced TIFF images of sounding sheets held by LINZ throughout the SW Pacific region. Some of these sounding sheets date back to the 1950s. The polygons comprising the index show the extent of each original hard copy sheet - not just the soundings shown on the sheet. The attributes attached to each polygon will enable you to view, amongst other attributes, the date and scale of the bathymetric data shown on the sounding sheet.
Please refer to the LINZ Bathymetric Index Data Dictionary for further information about the attributes of this dataset.
The georeferenced TIFF images are not downloadable from the LINZ Data Service
Requests for sounding sheets 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 sounding sheets of interest.
The provision of this 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.
