Renovating in Whau
Stats NZ publishes dwelling alteration consents by Auckland local board, which makes the board the smallest geography where an honest answer to "what do renovations cost around here" exists. Here is Whau’s: the trailing twelve months, the ten-year shape, and where it sits among the 21.
$96,082
Average declared value per dwelling alteration consent in Whau, twelve months to May 2026. That is 41% below the Auckland average of $163,752, and ranks 14 of 21. Declared value is the applicant’s own estimate of build cost at consent time and excludes land.

Alterations = consents to alter or add to an existing dwelling (Stats NZ series "Dwelling units / Altered"). Values are the consented build cost excluding GST as recorded on the consent, not what the work finally sold for.
Read the count and the value together. A board can carry a high average because a small number of large reconfigurations dominate it, or a low average because a lot of modest additions do. Neither is better work.
Ten years
The shape of alteration consent value, month by month
One hundred and twenty months of declared value, in millions of dollars. Monthly consent data is lumpy by nature — a single large consent moves a small board’s month — so read the shape, not the spikes.
