  • In addition to contour lines, relief shading helps visualise the terrain. Hills and valleys are shaded as if they were illuminated from the north-west. Relief layers were generated for each sheet, and specifically for use in the Topo50 map series. There may be subtle differences in the relief shading of adjacent map sheets. Where no contour information exists, relief shading has not been produced. The Topo50 map series provides topographic mapping for the New Zealand mainland, Chatham Islands, offshore islands, and offshore dependancies at 1:50,000 (some of the islands at 1:25,000) scale. For some small islands the printed map scale is 1:25,000. Although presented at 1:25,000 this layer, for all intents and purposes, forms part of the Topo50 map series.

  • New Zealand Contiguous Zone The contiguous zone is a zone of 12 nautical miles beyond the territorial sea in which New Zealand, as the coastal state, may take action to prevent or punish any infringement of its customs, fiscal, immigration or sanitary laws or regulations applicable within its land territory or territorial sea.

  • New Zealand Territorial Seas The territorial sea is the belt of sea adjacent to the coast out to a distance of 12 nautical miles from prescribed baselines over which New Zealand, as the coastal state, has the same rights of sovereignty that it exercises over its land territory subject to the right of innocent passage (and transit passage through any straits used for international navigation) of ships of other states. 'Innocent passage' excludes fishing activities.

  • Index Tiles ONLY, for actual orthophotos see layer [Auckland Island 0.5m Satellite Imagery (2014-2021)](http://data.linz.govt.nz/layer/107362) Satellite Imagery of the Auckland Islands captured between 2014 and 2021. Coverage encompasses Auckland Island, Adams Island, Disappointment Island, Enderby Island, Ewing Island, Rose Island and Dundas Island. Imagery was captured for Toitū Te Whenua Land Information New Zealand by Maxar, Inc. Data comprises: • 136 ortho-rectified RGB GeoTIFF images in NZGD2000 / Auckland Islands TM 2000 projection, tiled into the LINZ Standard 1:5000 tile layout • Tile layout in NZGD2000 / Auckland Islands TM 2000 projection containing relevant information. Please refer to the tile index layer for specific details, naming conventions, etc. Imagery supplied as 50cm pixel resolution, 3-band (RGB) uncompressed GeoTIFF. The spatial accuracy is <8.5m at 90% confidence

The Kermadec Island Group data and maps, although captured and presented at 1:25,000 scale are, to all intents and purposes, part of the Topo50 series.
