Marine Management Areas form part of the Northland Regional Coastal Plan

The coastal marine area has been divided up under the following six zones or Marine Management Areas: Marine 1 (Protection), Marine 2 (Conservation), Marine 3 (Marine Farming), Marine 4 (Moorings), Marine 5 (Port Facilities), Marine 6 (Wharves).

Appropriate Scale of Use 1:25,000

Land Environments of New Zealand (LENZ) is a classification of fifteen climate, landform, and soil variables chosen for their relevance to biological distributions. Classification groups were derived by automatic classification using a multivariate procedure. Four levels of classification detail have been produced from this analysis, containing 20, 100, 200, and 500 groups respectively.

Australia's River Basins 1997 is the result of a joint State and Commonwealth project to create a national spatial database of major hydrologic basins. The data has been derived from topographic maps at scales ranging from 1:10 000 to 1:250 000. These basins are the primary building block for the collection of national hydrologic data and the assessment of water resources.

Australia is divided into drainage divisions. The drainage divisions are sub-divided into water regions, which are in-turn sub-divided into river basins. Statistics are gathered and used at all three levels.

This database contains boundary information for 12 divisions, 77 regions and 245 basins. It also contains, for each basin, information relating to its individual basin/region/division name and number. State borders are also included in the data. Data for Division XIII Distant Islands Division is not included.

The former Australian Water Resources Council (AWRC) formally defined the drainage divisions and river basins in the early 1960s and, with minor modifications resulting from improved mapping of the inland arid zone area, has been the basis for the study of Australian hydrology since. The drainage divisions were defined by both the major topographic features of the continent and the main climatic zones to give broadly homogenous hydrologic regions. Within the drainage divisions, the river basins are defined by the major watershed lines.

Identifies soils that are of highly productive and versatile nature from subdivision and land uses that are likely to result in their loss or permanent removal from primary production.

This interpretation of Highly Versatile Soils is derived from the New Zealand Land Resource Inventory (NZLRI) Land Use Capability set from Landcare Research Ltd.

The REC groups rivers and parts of river networks that share similar ecological characteristics, including physical and biological. Rivers that share the same class can be treated as similar to one another and different to rivers in other classes. The REC classification system groups rivers according to several environmental factors that strongly influence or cause the rivers’ physical and ecological characteristics (climate, topography, geology and land cover). A catchment is a polygon that defines the upstream watershed of a river system or sub-system. Land cover within the catchment was used to populate the river classification factors (see table 1.1 of the User Guide www.mfe.govt.nz/environmental-reporting/about/tool... ).

Wellington Corrosion Zone as 500m buffer from coastline.

For purposes of defining corrosion zone for building consent applications.

Calculated as a 500m buffer from Mean High Water Springs (MHWS). MHWS is calculated at 0.855m elevation above 0 sea level using a 1m digital elevation model.
