Building Consent Data

K Yang made this Official Information request to Statistics New Zealand

This request has an unknown status. We're waiting for K Yang to read a recent response and update the status.

From: K Yang

Dear Statistics New Zealand,

Could you please release the following data at territorial authority level? In terms of the length of the data, ideally it would be best if you can release the data from 2000 to 2020 if this is possible. In terms of the frequency of data, I would like to have yearly data if possible. Thank you very much. I am looking for the following three series.

1.The total land area of a residential house where a new building consent (not altered building consent but only new building consent) is issued in a territorial authority in a given year.

For example, if in 2000 Far North District issued two new building consents for residential houses listed as below.
1.1 The first new building consent is issued to a residential house with a land area of 100 sqm
1.2 The second new building consent is issued to a residential house with a land area of 150 sqm
The data I would like to have for Far North District in 2000 is 100+150=250 sqm

2.When a new building consent (not altered building consent but only new building consent) is issued, a residential house may or may not get built. I would like to have the number and floor area of residential houses that actually got built in a territorial authority in a given year.

3.Two of the following four series (3.1+3.2 or 3.3+3.4)
3.1 Average sale price of newly built residential houses per sqm in a territorial authority in a given year
3.2 Average sale price of newly built residential houses in a territorial authority in a given year
3.3 Average sale price of all residential houses (including new and existing stocks) per sqm in a territorial authority in a given year
3.4 Average sale price of all residential houses (including new and existing stocks) in a territorial authority in a given year

Thank you very much. I am looking for data related to a study of housing supply in New Zealand. Your contributions will be acknowledged when the study is published.

Yours faithfully,

K Yang

Hello,

We are currently processing your request.

Stats NZ currently produces statistics on the number, floor area, and
value of consents for dwellings. Please refer to
[1]https://www.stats.govt.nz/topics/building

Total land area statistics, related to these consents (in reference to
your first question), have not been produced before, although we may be
able to produce an experimental series.

Due to the nature of the data it will have some limitations, and may take
some time to produce.

If we are able to produce the data, the limitations may include (but are
not limited to):

o Imperfect matching between street address descriptions recorded on the
building consents data we receive and the parcel on which a dwelling
will be built on.
o In some cases, multiple homes may be built on the same piece of land.
These homes may be built at different times, which can affect the
accuracy of the results.

We do not currently hold any information on the final amount of new
dwellings built within each Territorial Authority (question 2), or any
sales that have occurred (question 3). We only collect data on building
consents issued, some information on a sample of building projects, and
information on property transfers, although these aren’t limited to just
sales. Each Territorial Authority collects information on the issuance of
Code Compliance Certificates which will be a better indicator of the
amount of new dwellings built.

An experimental piece done previously has been used to provide insights
into the proportion of dwelling consents that actually get built. This can
be found here:
[2]https://www.stats.govt.nz/experimental/e...

The estimated time it will take to produce these estimates will be around
10 hours in total. The cost associated with this work will be $1,550 +
gst.

Would you be able to notify us of the urgency of your request so that we
may be able to set an appropriate deadline ?

If you are associated with a university, this work may be covered by the
CONZUL Agreement. Please refer to

Please contact me if you have any questions or would like to discuss your
request in more detail.
