ABC News has been chewing on a question doing the rounds in Canberra: should Australia copy New Zealand's 83-page building code? Next to the National Construction Code, which sprawls across three volumes, the Housing Provisions and hundreds of referenced standards, an 83-page rulebook sounds like a dream. Less reading, less ambiguity, more time on the tools. Before anyone gets excited, it's worth pulling apart what that 83-page figure actually buys you, because the answer matters for how you quote and run jobs right now.

The 83 pages are not the whole story

New Zealand's building code is short because it is almost pure performance language. It tells you what a building must achieve: stay standing, keep water out, let people escape a fire. The detail on how to achieve it lives somewhere else, in acceptable solutions, verification methods and the standards they reference. Kiwi builders still work from thick documents. The code is short; compliance isn't.

Australia already runs the same model, just packaged differently. The National Construction Code has been performance-based since the 1990s. The performance requirements, the legal core of the code, are a small fraction of the total page count. The bulk is deemed-to-satisfy pathways: the recipes that let you point at AS 1684 for your timber framing, follow it, and know the surveyor will sign off without an engineer's letter. Cut those pages and the obligations don't shrink. They move, either into separate documents you buy, or onto your shoulders as performance solutions that need expert evidence.

So the honest version of the question isn't "83 pages or 2,000". It's "where do you want the detail to live, and who carries the risk when it's ambiguous". A builder who has ever argued with a certifier over an ambiguous clause knows that vague and short can cost more than long and specific.

What National Construction Code reform would mean for your quoting

Whatever Canberra lands on, the money question for a builder is churn. Every time the code changes, three things hit your business:

• Quotes signed under one edition, built under another. A fixed-price contract that straddles a code change is a margin risk. Your quote should state which NCC edition and state variations it was priced against, and your contract needs a variation mechanism for regulatory change. If your quotes live in scattered spreadsheets, that assumption never gets written down. It's one reason to keep rates and inclusions in one system, and we've compared the options in our guide to the best construction estimating software in Australia.
• Requoting time. When provisions change, your standard details and rate build-ups need reviewing. That's unbillable admin, and it lands in your price the same way GST does, whether you itemise it or not.
• Documentation load. A shorter, more performance-heavy code would mean more jobs needing evidence of suitability rather than a simple "complies with DTS". That's more paperwork per job, not less, and it's the kind of thing that sinks builders who run their job records out of a ute console.

None of this is a reason to oppose simplification. Plenty of the code's complexity is real bloat, and the industry has been saying so for years. It's a reason to watch what "simpler" means in practice before assuming it means less admin for you.

What doesn't change, whatever the page count

The physics stays put. A staircase still has to hit riser and going limits whether the rule sits in an 83-page code or volume two of the NCC, and getting the set-out right before you cut stringers is still on you. Our free stair calculator does that arithmetic in seconds, under any edition of the code.

The same goes for waterproofing falls, bushfire construction levels and energy provisions. Reform changes where the answer is written, not whether you need it on site at 7am.

What to do while the debate runs

Three practical moves, none of which need a politician:

1. Note the NCC edition and state variations on every quote and contract from here on.
2. Put a regulatory-change clause in your standard contract if it isn't there already.
3. Check the current requirements at ncc.abcb.gov.au, where the full code has been free to access since 2019. Don't price off memory or off a mate's recollection of the old rules.

The New Zealand comparison makes a good headline, and some version of simplification is probably coming. Until it does, the builders who win are the ones whose quoting and job records are tight enough to absorb whatever edition lands next.
