Value of residential building work put in place in the Wellington Region, New Zealand

Non-residential buildings: work on new buildings, plus alterations and additions to existing buildings. There are seven categories:
- hotels, motels, boarding houses, and prisons (accommodation buildings)
- hospitals, nursing homes, and other health buildings (health buildings)
- education buildings
- factories, industrial, and storage buildings
- commercial buildings (includes shops and offices)
- social, cultural, and religious buildings
- farm buildings.
Residential buildings: work on new dwellings, such as houses, flats, and apartments. The value of alterations and additions to residential buildings also includes domestic outbuildings, such as garages.
Value: value of building work in current prices.
Volume: values with price changes removed, expressed in September 1999 quarter prices. Also known as deflated values or constant price series.

Value of building work under a set threshold is estimated through a statistical model.

Non-building construction work, such as roads and bridges, is excluded.

The value threshold used to determine which building projects are surveyed in the Quarterly Building Activity Survey, and which have activity modelled from consent data, was raised again in the December 2021 quarter.
For new residential building projects, the survey threshold increased to $1,400,000, reflecting recent increases in construction industry costs. The survey threshold for non-residential building projects is unchanged at $1,900,000.
From the March 2020 quarter onwards, Stats NZ have applied model adjustments to account for the impacts of COVID-19 on building activity (such as building activity delayed due to alert level 4 lockdowns or supply constraints). These adjustments are revised from time to time as improved data becomes available.

The Building Activity Survey releases provide estimates of the value and volume of work put in place on construction jobs in New Zealand. The value of building work includes residential building work and non-residential building work, which are summed to give all building work. Non-building construction work, such as roads and bridges, is excluded.
The value of building work put in place measures activity in the construction sector, and complements building consents issued information (which represents the intention to build).

Up until December 2014, this dataset was based on a postal survey sent to contact details associated with each council's building consent.
From 2015, this dataset is based on modelled administrative data supplemented by a postal survey. A postal survey is sent for building work above a certain threshold, which is reviewed regularly.

There are no changes for non-residential buildings – the consent value cut-off remains $1,900,000 and the modelling parameters are unchanged.
