New dwelling consent and household growth

Why it's important

Dwelling consent and household growth tell us about the rate of residential building activity and is an indicator of economic activity.

Key points

  • In the year to September 2020, there were 4,758 new dwelling consents issued across Greater Christchurch. For Christchurch in the same period, there were 2,773 consents (58%), 1,400 (29%) in Selwyn and 585 (12%) in Waimakariri.
  • The number of households across Greater Christchurch increased by 4,703 in the year to June 2020. For Christchurch that was an increase of 2,800 households (60%), with 1,172 in Selwyn (25%) and 731 in Waimakariri (16%).

The loss of 5,600 households from Christchurch was due to the Canterbury earthquakes. Conversely, both Selwyn (655) and Waimakariri (692) experienced an increase in household numbers during the period.

In more recent years the data would suggest that the number of new dwelling consents being issued is much more closely matched to the annual increase in the number of households across the three territorial authorities.

Data notes

This indicator approximates the demand for, and supply of, new dwellings. It measures changes in demand and how responsive supply is.

The number of new dwelling building consents is lagged by six months (presented as a 12-month rolling average), to account for the time taken from consenting to completion. It is not adjusted for non-completions or for demolitions. It is used as a proxy for supply.

The most recent resident population, divided by the local average housing size, is used as a proxy for demand. Both sets of data are sourced from Stats NZ.
