This dataset is a collection of individual hydrographic charts for New Zealand's Offshore Islands, and has been designed to provide a quick way to group, view and/or download charts within this region.
Note: This set contains charts at a variety of scales. Use of LDS web map tile services for this set is not recommended as the scaled charts overlap.
All charts are available for individual download through the LINZ Data Service, and will be updated as new data becomes available.
These charts are based on the official Raster Navigational Chart series produced by the New Zealand Hydrographic Authority, available on the [LINZ website](https://www.linz.govt.nz/sea/charts/nzmariner-official-raster-navigational-charts-rncs).
THIS DATA DOES NOT REPLACE NAUTICAL CHARTS AND MUST NOT BE USED FOR NAVIGATION.
