Preliminary data indicate that the area of urban and rural residential use on versatile land in the Waikato region has been increasing since 2001.
This indicator is based on the area (ha, hectares) of versatile land (Land Use Capability classes 1-4) in urban and rural residential use in the Waikato region at four time steps (2001, 2008, 2012, and 2017). Urban residential area is defined to be land parcels of 0.00-0.50 ha in size with a dwelling whereas rural residential area is defined to be land parcels 0.51-2.00 ha in size with a dwelling.
Note that this indicator and the data presented are preliminary and yet to undergo peer review.
The expansion of urban and rural residential use generally results in a reduction in land available for primary production. The loss of land, particularly the most versatile land (i.e. Land Use Capability classes 1-4) available for primary production, may have various economic, environmental, and social impacts including:
Monitoring residential expansion onto versatile land provides information for councils, land developers and communities about which areas in the region are experiencing increasing pressures through urbanisation or peri-urban growth. This can helps councils manage rates of residential expansion onto versatile land through policies and plans.

DATA SOURCE AND SUPPORTING INFORMATION
Residential expansion onto versatile land refers to the change in area of versatile land in urban and rural residential use. Land Use Capability classes 1-4 define versatile land. Urban residential area is defined to be land parcels of 0.00-0.50 ha in size with a dwelling whereas rural residential area is defined to be land parcels 0.51-2.00 ha in size with a dwelling.
The analysis uses the Land Information New Zealand (LINZ) primary land parcel layers and electoral address point data associated with each of the four time steps examined (2001, 2008, 2012, and 2017). Electoral address points were used to indicate the presence of a dwelling. Land versatility was assessed using the NZ Land Use Capability (LUC) Classification (Lynn et al., 2009). The regional and territorial authority boundaries were obtained from Statistics New Zealand. Total change in area over the 16 year period (2001-2017) was averaged over the period to give an indication of average annual change.
Update details: It is anticipated that this indicator will be updated at least every five years.
