This data contains the the Fishing Restrictions for a specific fisheries management region and the Submarine Cable and Pipeline Protection aspects of mapping undertaken by the Department of Conservation as published December 2004 in “Area-based restrictions in the New Zealand marine environment”. This report should be consulted where more detail regarding this data is required. See Lineage:

Mapping Detail
The fishing restrictions were derived using the legal descriptions in the appropriatestatutory regulation. The boundaries of individual restrictive provisions were mappedusing coordinates (latitude, longitude), LINZ NZMS260 Topographic coast 2005,LINZ EEZ, LINZ Territorial Sea, all are defined in WGS84. Location descriptionswhere also used when coordinate descriptions wereinappropriate or undefined.
Submarine Cables and Pipelines were derived using the legal descriptions in theappropriate statutory regulation. The boundaries of individual restrictive provisionswere mapped using latitude and longitude coordinates.
Mapping Methodology
Mapping is captured and displayed in WGS84 decimal degrees (lat/long).
One polygon area may contain more than one restriction (see Attributemethodology 2.1 above for details).
Geographic coordinates listed in the legal descriptions have been plotted onlywhere there was no obvious alternative way to define the point in question(e.g.: landmark).
Where buffering has been required to define a boundary, this has beencarried out by computation with outer boundaries generalized using 60segments per circle.
Rocks, islands and islets have not been removed from mapped areas.
Areas were calculated in km2 using a Spherical Area Projection (areamaintained) and are rounded where possible to the nearest 10km. Thecalculation relates to the area of the restriction that covers the ocean, noislands are included. Where inland waters are included as part of therestriction then these are not included as part of the calculation.
The coastline used for mapping of all restricted areas was the Mean HighWater coastline extracted from LINZ 1:50k NZMS260 Topographic 2005.
Where EEZ and/or territorial water boundaries form part of a defined restrictedarea, the boundaries used are as supplied by LINZ.
In order to map marine habitats consistently across all bioregions, Geographic Information System (GIS) datasets were sourced, where possible, that extended across all of the New Zealand Territorial Sea. The intent was to avoid bias in the representation of habitats associated with differences in the extent and detail of surveys in different regions. The disadvantage of this approach, however, is that the more detailed surveys available or underway in some regions (Neale et al. 2007, WCMPF 2010, Benn 2009; Kettles & Hughes 2009; Kerr 2010, Morrison et al. 2010) are not included in this broad scale analysis. These surveys should be included in more detailed regional assessments.
The extent of habitat mapping was mainly defined by the Land Information New Zealand (LINZ) coastline, the LINZ boundary (2004) to the New Zealand Territorial Sea (within 12 nautical miles of the coast and islands), estuaries from the National Institute for Water and Atmospheric Research (NIWA) New Zealand Estuary Environment Classification (Hume 2007) and bioregions defined in the Marine Protected Areas Policy and Implementation Plan (Department of Conservation and Ministry of Fisheries 2005).
Within these bioregions, spatial data layers for depth, substrata and exposure were overlaid in ArcGIS to approximate the habitat categories described in the Coastal Classification and Mapping Scheme (Appendix 1, Ministry of Fisheries and Department of Conservation 2008). In some cases, categories were modified according to what data were available and to provide consistent, justifiable, readily interpreted habitat descriptions that adequately reflect major patterns in marine environments. The data sources and habitat categories that were used are described in the report:
Department of Conservation and Ministry of Fisheries(2012)."Coastal marine habitats and marine protected areas in the New Zealand Territorial Sea: a broad scale gap analysis. Wellington, New Zealand.
More detailed descriptions of source data within the New Zealand Territorial Sea are described in separate coverages for NZ marine bioregions; NZ depth, NZ substrata and NZ exposure. The GIS datasets were combined using the unioncommand in ArcGIS and ArcINFO 9.3. This command overlays and dissects the intersections between overlapping areas from different datasets. The function creates polygon features attributed with fields of variables from each of the source data sets. These fields were used to create composite categories derived from combinations of the different levels in the depth, substrata and exposure fields. The ArcGIS ‘eliminate’ command was used to minimise the large numbers of elongate ‘sliver polygons’ resulting from overlaying disparate datasets. Slivers less than 1 hectare in area were dissolved into the adjacent polygon with the longest joint boundary.
Because of the number of small slivers and extent of the data set, boundaries between habitats classes were sometimes generalised resulting in small departures (usually <50m) from the lines of the original habitat data including the coastline. Regard should then be given to the fitness for use of this data for use other than its intended purpose as a broad scale classification and gaps analysis. This should be taken into account particularly for viewing and analysis at fine spatial scales.
In some cases, the source datasets did not completely overlap and for some areas a full classification using all environmental drivers was not possible. In most cases the area involved was small and polygons were merged with the nearest feature with the longest joint boundary. For parts of some estuaries, no nationally consistent data on substrata were available. These areas were mapped simply as unclassified estuary. This category was not however included within habitat counts for each bioregion.
