What follows is the standard this site holds itself to. It is written down because outdoor building work in New Zealand is badly served by the material available about it: most of it is advertising, and most of the rest was copied from advertising.
On cost figures
A price here is always a range, attached to a region and to a stated scope. That is not hedging. Ground conditions, access and season move an earthworks or wall price more than any other variable, and a single national figure would conceal exactly the information a reader needs. Where the honest answer is that a number cannot be pinned down, the article says so and explains which unknown is doing the damage.
On technical claims
Gradients, treatment levels, pile depths, drainage falls and wind zones get checked against published material before they appear — MBIE guidance, BRANZ research, council documents, WorkSafe, NIWA and the standards bodies. Nothing technical is repeated from another article on the strength of it having been published somewhere else. Where a figure would change what a reader decides, the source behind it is one a reader can go and read.
On consents and boundaries
These are described in general terms and nothing more. No clause numbers are invented, no fee schedule is quoted from memory, and no reader is told whether their particular job needs consent. That determination belongs to the council holding the district plan, and an article that pretends otherwise is doing the reader active harm.
On being wrong
Things published here turn out to be wrong or go out of date, and when they do the article gets revised — in the body text, where a reader will actually encounter it, rather than in a footnote nobody reads. No deadline here is tight enough to justify publishing something the writer is not confident in.
On money
Nothing is sponsored and no position in any article can be bought. Where a piece names a category of trade, it is describing who does that class of work, and there is no arrangement of any kind sitting behind the mention.
