"Dwelling occupancy status provides information on whether dwellings are occupied or unoccupied, or are under construction. Dwelling occupancy status provides an indication of the housing stock available in New Zealand for habitation. Information on dwelling occupancy status can be used to evaluate, appraise, and predict urban infrastructure requirements, such as transport, sewerage, and water.
Dwelling occupancy status is a hierarchical classification with two levels. Level 1 of the classification has three categories (excluding residual categories), and level 2 of the classification has four categories. At level 2, the category 'unoccupied dwelling', is split into 'residents away' and 'empty dwelling'."
