A subset of Critchlow NationalMap consisting of Built Up areas defined by LINZ and modified by Critchlow to encompass the extent of built up urban areas including commercial and residential categories. These are named urbanised areas.

'Urban' is defined as 'of, pertaining to, or constituting a city or town; occurring in or characteristic of a city or town'. In the majority of cases, an urban area will be characterised by high population density, small land holdings (regularly less than 0.4 hectares), and zoning that is compatible with high density commercial, industrial and/or residential activity.

Critchlow modifications to the original dataset include the identification of detailed boundaries for built up areas from the latest available aerial imagery supplied by LINZ. Therefore the dataset contains whole urban areas not included in the original LINZ dataset.
