The West Coast area includes significant areas of Kaipara South Head, the Ōkahukura (Tāpora) Peninsula and the eastern coastal margins of the Kaipara Harbour. The area is characterised by a predominance of rural production activity, particularly pastoral farming activities and forestry and its significance to Māori. Long, high-energy beaches backed by sand dunes are located along the coast, terminating in the significant high dune landforms and Papakanui spit at South Kaipara Head. Three main roads serve the area – State Highway 16, South Head Road and Run Road-Journey's End. There are high-amenity views of the harbour from State Highway 16 in particular.
Flat coastal alluvial plains are a special landscape feature in the Kaipara Harbour catchment. These are backed by a convoluted coastline with rolling hills. This harbour is highly tidal with extensive areas of exposed intertidal flats and defined low tidal channels and occasional mangrove communities. The remaining natural areas are important due to past vegetation clearance and wetland drainage. Activities such as sand extraction, marine farming and tidal energy generation occur in the Kaipara Harbour.
Significant bird habitats are present along the coastal margins and in the harbour, particularly around the sand islands at Tāpora. Tāpora, Wharehine and Port Albert are sensitive to development due to the elevated nature of many of the surrounding roads, and due to the rolling and often open natural of the land which also connects to the low lying alluvial plains.
Development has increased in particular along the west coast of the Kaipara Harbour and along South Head. A pattern of typically large properties and low-density settlement provides a rural and semi-remote character.
Woodhill Forest along the western margins of South Kaipara peninsula provides production, recreation, sand stabilisation and landscape functions. It is a significant site for active sports such as mountain biking.
Topography and private land ownership limits access to the coastal edge in many areas. However, Ātiu Creek Park provides public access to the Ōruawhero arm of Kaipara Harbour.
Small bach communities are located at Shelly Beach, Journey's End and Port Albert, with Shelly Beach providing the main boat launching facility.
South Head and the coast of the Kaipara Harbour while generally meeting the above description are noted as areas which are also recognised as being under pressure for development that is not directly related to rural production activity due to the coastal location and proximity to metropolitan Auckland.
However, there are areas of significant landscape – identified in the overlays as ONC, HNC, and ONL, which are considered to be at risk of degradation. Control over the built environment in these areas is considered prudent in order that the semi-remote character and the rural/coastal landscape, environmental and amenity values present are retained.
To recognise these qualities the whole area isincluded in the Rural Coastal zone with particular development and subdivision controls that enable normal rural activities such as farming and forestry to continue as permitted activities, albeit subject to more stringent environmental controls (relating to buildings, earthworks on sites 40 hectares and less in area (that are not already provided for as a Permitted Activity), tree and bush removal, and wetland/watercourse modification to ensure they respond sensitively to the landscape qualities present.
Development controls to recognise these features and associated values include a slightly higher height allowed for dwellings, with slightly greater maximum height for farm and forestry rural accessory buildings within an identified ONL.
