Where the facts come from
Rules come from the bodies that set or explain them: MBIE on building consent and contracts, the Electrical Workers Registration Board on wiring, Consumer Protection on your rights, the Disputes Tribunal on small claims and the Privacy Commissioner on your details.
Weather and sea spray facts on our local pages come from NIWA, BRANZ and MBIE. Door and opener facts come from the makers' own pages and manuals: Dominator, B&D NZ, Garador and Merlin.
Each fact is stored with the page it came from and the date it was read, and a page that uses the fact lists that source at the bottom so you can open the original.
How we write
- A maker's figure stays the maker's. Headroom, weight and warranty figures are given as Dominator's or B&D NZ's, never as a general rule.
- Building consent always goes to the council. MBIE's guidance doesn't name garage doors, so we never say a job is exempt.
- Springs, cables and drums are always jobs to leave alone, in the makers' own words.
- No prices, cost ranges or rates. The dollar figures on this site are legal limits, such as the $30,000 written contract rule.
- No made-up jobs, customers or reviews.
- Some photos here are illustrations made with an AI image tool. None shows a real job or a business in our network.
- Every number on a page has to match a number in our fact base, and an automated check stops the page going up if one doesn't.
What stays off the site
If a source can't be read, the fact waits. Some government and council sites could not be read when these pages were written, so those pages stick to what other official sources confirm, and give no figure we couldn't check.
Standards such as AS/NZS 4505 are paid documents, so we don't quote clause figures from them. When a page needs a test, like the monthly reversing check, it gives the maker's steps and names the maker.
Who writes and checks
The Door Hero publishes these pages and stands behind them. The Door Hero doesn't do door work, so the pages lean on what regulators and makers publish rather than on anyone's opinion, and every number on them comes from the fact list described above.
Corrections and changes
When a rule changes or a mistake turns up, the page is corrected against its source, and the updated date at the top of the page moves with it.
