Questions
How many building consents were issued in Castle Hill?
In the year to September 2026, Stats NZ counted 2,424 new homes consented in the Selwyn District council area, with $1.1b of residential and $216m of non-residential building work.
What is a building consent?
Written approval from a council (a building consent authority) that planned building work complies with the Building Code. Most new buildings, additions, structural alterations, fires and plumbing and drainage work need one; some minor work is exempt under Schedule 1 of the Building Act 2004.
Where do these figures come from?
The official counts are Stats NZ’s monthly Building consents issued release (CC BY 4.0), covering every consent every council issues. The individual consents listed are ones we hold from councils’ records and other public sources; they are not a complete list for every council.
