About the Postcode Network File:The Postcode Network File is the authoritative definition of the New Zealand Post Postcode Network. It includes approximately 1800 postcodes incorporating:• Urban delivery postcodes• PO Box and Private Bag postcodes• Rural Delivery (RD) postcodesThis is version V2021Q2V01in NZTM (New Zealand Transverse Mercator) ProjectionNote: There are a number of additional locations used for counter delivery or Community Mail Box delivery that are not included in the Postcode Network File. This is because these locations are not official New Zealand Post Box Lobbies. A listing of these is available at www.nzpost.co.nz/postcodefinderThe primary purpose of postcodes is to assist in the efficient and accurate delivery of mail. Used in New Zealand since 1977, this major revision of postcodes is designed to provide a unique delivery address for all postal addresses on the New Zealand Post network. The postcode boundaries take into consideration New Zealand Post mail sorting requirements, the density of delivery addresses and the proximity of identical or similar street names. Please note that postcode boundaries do not necessarily reflect suburb boundaries. Urban and rural postal delivery postcodes are represented by a single-part or multi-part geographic area while postcodes associated with Box/Bag delivery are represented by a single point location (PO Box lobby). In rural areas the Rural delivery identifier (RD number) and New Zealand Post Mailtown is included and for Box/Bag lobbies the lobby name is listed.The Postcode Network File is designed to enable businesses and policy-makers to integrate postcodes within Geographic Information Systems (GIS) applications to assist in planning, modelling, business intelligence and decision making. The data can be represented in two dimensions (mapped) or modelled against other data such as physical addresses, city or town boundaries, census meshblocks and land valuation areas. Although the Postcode Network File includes full national coverage, it should be noted that not all physical addresses contained within a postcode boundary receive mail delivery from New Zealand Post.

This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers: - [NZ Coastlines (Topo 1:50k)](http://data.linz.govt.nz/layer/258-nz-coastlines-topo-150k/) - [NZ Island Polygons (Topo 1:50k)](http://data.linz.govt.nz/layer/288-nz-island-polygons-topo-150k/) - [NZ Auckland Is Island Polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/959-nz-auckland-is-island-polygons-topo-150k/) - [NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/932-nz-campbell-is-motu-ihupuku-island-polygons-topo-150k/) - [NZ Antipodes Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/978-nz-antipodes-is-island-polygons-topo-125k/) - [NZ Kermadec Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/908-nz-kermadec-is-island-polygons-topo-125k/) - [NZ Bounty Is Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/992-nz-bounty-is-island-polygons-topo-125k/) - [NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k)](http://data.linz.govt.nz/layer/893-nz-snares-is-tini-heke-island-polygons-topo-125k/) - [NZ Chatham Is island polygons (Topo, 1:50k)](http://data.linz.govt.nz/layer/86-nz-chatham-is-island-polygons-topo-150k/) Islands from the NZ Island Polygons layer that lie within the NZ Coastline and Chatham Islands areas (i.e. islands in lakes, rivers and estuaries) have been removed. The GIS workflow to create the layer is: 1. NZ Coastlines were converted from a polyline to a polygon using a polyline to polygon tool. 2. The resulting coastal polygon was then used as an input into an erase tool and run against the NZ Island Polygon layer to remove all islands lying within the NZ Mainland and Stewart Island. 3. This was then merged with the NZ Chatham Is island polygons (Topo, 1:50k) that have had the islands within the main island polygon removed, NZ Auckland Is Island Polygons (Topo, 1:50k), NZ Campbell Is / Motu Ihupuku Island, NZ Antipodes Is Island Polygons (Topo, 1:25k), NZ Kermadec Is Island Polygons (Topo, 1:25k), NZ Bounty Is Island Polygons (Topo, 1:25k) and NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k) layers using a merge tool. 4. Lake Onoke from the NZ Lake Polygons (Topo 1:50k) layer and Te Whanga Lagoon from the NZ Chatham Is lagoon polygons (Topo, 1:50k) layer were then erased from the resultant polygon layer to include these two water bodies in the coastline definition. For more detailed description of each layer refer to the layer urls above.

The seamount catalogue presents a synopsis of the physical characteristics of seamounts within the “New Zealand region” (taken here as the area bounded by 24°S, 167°W, 57°S, and 157°E). Data are collated on features with a vertical elevation of 250m or greater (thus, the term seamount is used here for discrete bathymetric features with ≥250 m of relief) with some features of 100 m or greater that are significant for the fishing industry being also included, but have presented these data in a way that accounts for differing interpretations of the terminology for undersea features of various sizes. The catalogue is maintained as a MS Excel spreadsheet.

Just Mussels LTD engaged NIWA to complete a benthic survey and assessment as part of a coastal permit application for an extension to marine farm 8321, in Wilson Bay, Pelorus Sound. This assessment comprised side-scan-sonar swath mapping of sites to characterise seabed topography, photoquadrats of the seabed to ground-truth the side-scans, samples of epifauana, diver observations and core sampling. The report indicated that the proposed extension is not expected to cause any significant adverse ecological effects. The ecological effects of farming the proposed additional mollusc species are likely to be no greater than the effects of farming green mussels. Farming of the algal species (as proposed) is unlikely to have any significant ecological effects. The report identifies a dense population of burrowing shrimp (Upogebia hirtifrons) adjacent to the inshore boundary of the site. However, the report notes that there is unlikely to be any significant detrimental effect of the proposed extension to the shrimp burrow habitat.
