A smoothed outline of Aotearoa New Zealand’s coast was used to construct coastal segments of roughly 10 km width (depending on complexity of the coastline), extending out to the 12 nm Territorial Sea limit. Both public and private protected lands can indicate areas of more natural levels of land-based inputs and include coastal areas important to marine species and connecting marine habitats. Public protected land area data from the Department of Conservation (DOC) including Reserve, Marginal Strip, Conservation Area and National Parks was used to calculate the proportion of area covered in each 10 km segment and. This process was repeated for Queen Elizabeth II private land covenants and then the proportions were added together to get total proportion covered. Because these segments don’t occur in isolation, a 10 km buffer was used around each coastal segment to capture land use in inland and adjacent coastal areas.

Limitations and Uncertainties:

We recognise that 10 km coastal segments are arbitrary boundaries for the NZ coastline, and further, that we extended all values for each polygon out to the 12 nm Territorial Sea boundary to allow better visualisation of how land-based inputs and population accessibility vary in NZ. This extension seaward is arbitrary, and does not incorporate likely decreasing impacts offshore from the coast. Segments for Stewart Island were not included and for coastlines with large, narrow inlets, such as in Fiordland, segments do not include the inner fiords as this would increase the segment size, making comparisons between segments less consistent.

Protected areas description: This Protected Area Layer contains land and marine areas, most of which are administered by the Department of Conservation Te Papa Atawhai (DOC) and are protected by the Conservation, Reserves, National Parks, Marine Mammal and Marine Reserves Acts. All of the areas have been identified spatially. The attributes in this dataset are derived from the National Property and Land Information System (NaPALIS), which is a centralised database for all DOC and LINZ administered land. The boundaries for most protected areas are derived from the Landonline Primary Parcel(s). In some cases, the boundaries may have been based on unsurveyed parcels defined to varying degrees of accuracy. As such please note that the boundaries are indicative only. The dataset includes reserves but it is not a complete set. Privately owned reserves are excluded from the dataset as they are not crown land. Also, the dataset does not contain a complete list of reserves “vested” in Local Authorities or “controlled and managed” by other organisations. The dataset is continually being updated however as errors or omissions are discovered and new land transactions are completed. The Department cannot guarantee the accuracy of the infromation but rather it represents best endeavours to maintain an accurate record of conservation land. A table of Protected Area associations to Primary Parcels is published in the [LDS here](https://data.linz.govt.nz/table/3561-protected-area-parcel-association/).
