Commentary

Residential buildings

The seasonally adjusted volume of residential building work rose 7.4 percent in the December 2009 quarter, following a fall of 4.2 percent in the September 2009 quarter. The increase in the December 2009 quarter is the largest since June 2004.

The trend indicates that the volume of residential building work has increased in the December 2009 quarter, following falls that began in the December 2007 quarter.

Statistics New Zealand building consents releases from 2009 have reported increases in the trend for the number of new housing consents issued. The increase in residential work put in place for the December 2009 quarter reflects this.

Construction prices for residential buildings, as reported in Capital Goods Price Index: December 2009 quarter, rose 0.1 percent in the December 2009 quarter, compared with a 0.4 percent fall in the September 2009 quarter.  The main driver for the latest increase was higher prices for dwellings and out-buildings (up 0.5 percent).

The seasonally adjusted value of residential building work, in current prices, rose 7.7 percent in the December 2009 quarter, following a 4.8 percent fall in the September 2009 quarter.

The trend, in current prices, for residential building work put in place has increased in the December 2009 quarter, following falls that began in the December 2007 quarter. 

For the December 2009 year, the unadjusted value of residential building work put in place was $5,875 million, down $1,448 million (19.8 percent) from the previous December year. Of this total, new dwellings fell $1,376 million (23.1 percent), and alterations, additions, and outbuildings fell $72 million (5.2 percent).

Non-residential buildings

The seasonally adjusted volume of non-residential building work fell 6.1 percent in the December 2009 quarter, following decreases in the previous two quarters. The volume of non-residential building work for the December 2009 quarter is now 12.9 percent lower than in the March 2009 quarter.

The trend indicates that the volume of non-residential building work has been falling for four quarters, and has fallen 13.2 percent since the recent peak in the December 2008 quarter.

Construction prices for non-residential buildings, as published in Capital Goods Price Index: December 2009 quarter, fell 1.0 percent in the December 2009 quarter. Lower labour costs and contractor margins, and falling material prices due to lower local demand, were cited as the main reasons for the fall.

The seasonally adjusted value of non-residential building work, in current prices, fell 6.9 percent in the December 2009 quarter, the fourth consecutive quarterly fall.

For the December 2009 year, the unadjusted value of non-residential building work put in place was $4,948 million, down $272 million (5.2 percent) from the previous year. The largest contributions to this decrease were from hospitals and nursing homes, down $172 million (39.0 percent) and commercial buildings, down $149 million (8.9 percent). Partly offsetting these decreases was an increase in education buildings, up $127 million (20.5 percent).

All buildings

The seasonally adjusted volume of all building work rose 0.7 percent in the December 2009 quarter, following a fall of 4.4 percent in the September 2009 quarter. This increase was driven by an increase in the volume of residential building work.

The trend indicates that the volume of all building work has been falling for eight quarters, and has fallen 25.6 percent since the most recent peak in the December 2007 quarter. 

The seasonally adjusted value of all building work, in current prices, rose 0.9 percent in the December 2009 quarter, following a fall of 5.4 percent in the previous quarter.

Table updates

  • The data for building consents issued in table 4 is now seasonally adjusted.
  • The series on residential mortgage yields is now available on Infoshare.

Sampling errors

Estimates for the value of building work put in place are derived mainly from a sample survey and are therefore subject to sampling errors. See following table for the sampling errors for the December 2009 quarter. 
 
Sampling errors for the December 2009 quarter
  Percentage of total value of work put in place
Residential buildings 3.9
Non-residential buildings 3.6
All buildings 2.7
 
The sample is designed to produce statistics at the 95 percent confidence interval limit. This means that for all buildings, for example, there is a 95 percent probability that the true value of work put in place this quarter is within plus or minus 2.7 percent of the published estimate.

Non-response imputation

For building projects where no survey response is received, Statistics New Zealand imputes values for work put in place, based on responses for comparable projects. See following table for the values imputed for the December 2009 quarter.
 
Non-response values imputed for the December 2009 quarter
  Imputed values $(million) Percentage of category value Percentage of all buildings value
Residential buildings 245 15.7   9.0
Non-residential buildings 58   5.0   2.1
All buildings 303 11.2 11.2

Excluded consents

Consents valued below $5,000 are excluded from statistics for the value of building work put in place. The value of excluded consents is estimated to be less than 1 percent of published values.

Low-value consents

These comprise residential building consents valued from $5,000 up to $45,000, and non-residential building consents valued from $5,000 up to $80,000. For these consents, it is assumed that:
  • the consent value represents the value of work put in place
  • consented work will be done during the month following the issuing of the consent.

Low-value jobs are therefore valued directly from consents (after a one-month lag), rather than by postal survey. See following table for the values included for the December 2009 quarter.

Low-value consents included for the December 2009 quarter
  Low-value consents $(million) Percentage of category value Percentage of all buildings value
Residential buildings   83 5.3 3.0
Non-residential buildings   64 5.5 2.3
All buildings 146 5.4 5.4
