Most NZ pre-trade-start meetings take 2-3 hours because the scope is worked out live in the room. A properly built Pre-Trade-Start sheet pulls the first 90 minutes onto paper, in writing, before the meeting. The result is a 45-minute confirmation that's RMBA-Guarantee-defensible and signed at the table.

The 8-12 trade queries that turn a meeting from 3 hours into 45 minutes

Quick answer: A Pre-Trade-Start Compliance Sheet for an NZ residential or light-commercial build contains 9 elements — cover and project header, scope confirmation from the quote, codes and standards table, shop-drawing and producer-statement chain, site coordination interfaces, 8-12 written trade queries, cost reasonableness check, open-items list, and sign-off. The sheet is emailed 5-10 working days before the meeting; the subcontractor answers in writing; the meeting itself runs 45 minutes and produces a document the RMBA Master Build Guarantee underwriter can read at year 3 or year 5.

Tight-site, mixed-use Auckland builds — town-house developments on small infill sites, apartment-block alterations, commercial-shell conversions to residential — typically run $800k-$2.5M build values on tight programmes with no laydown area and difficult crane access. For a Registered Master Builder running 3 or 4 active jobs in this market, the pre-trade-start meeting is the single highest-leverage 45 minutes in the procurement cycle — but only if the meeting actually takes 45 minutes.

In our experience, most pre-trade-start meetings on this type of build take 2 to 3 hours. The contractor and the subcontractor work through the scope ambiguity live, in the meeting. Half the meeting is "let me check the drawing" and "let me phone the engineer." The remainder is the actual coordination conversation. The Master Builder loses an afternoon, the subcontractor loses an afternoon, and the agreed answers are often verbal.

A properly built Pre-Trade-Start sheet pulls the first 90 minutes onto paper, in writing, before the meeting. The meeting itself is then a 45-minute confirmation, with the answers recorded against the sheet, signed by both parties.

What the RMBA Master Build Guarantee implies for pre-start discipline

The Master Builders Association 10-year Master Build Guarantee covers structural and weathertightness defects on residential work where the build is delivered by a Registered Master Builder. The Guarantee is underwritten and the cover is real — but the underwriting expects the Master Builder to have run the build to a documented standard.

Two practical consequences:

The subcontractor scope has to be definable. A Master Builder defending a Guarantee claim later needs to be able to show what each trade was contracted to do. "Roofing as per quote 10933" is not a scope. "Roofing as per the manufacturer's published datasheet, MRM CoP §4.5, E2/AS1 §8.4.4, drawings A3.01-A3.04 Rev D, with the named flashings, fasteners, and underlay" is a scope.
The compliance chain has to be filed. Manufacturer warranties, producer statements, code-compliance certificates. The Master Builder doesn't have to be an expert in every code clause — but the file has to show that the right trades were asked the right questions at the right time.

A Pre-Trade-Start sheet built around these two things is what turns a Guarantee from a marketing line into an actual underwritten cover.

The Auckland tight-site additions to a generic Pre-Trade-Start template

Inner-Auckland tight-site, mixed-use builds add three elements that a generic suburban version doesn't need:

1. Programme dependency mapping. On a tight-site build with no laydown area, every trade depends on the previous trade vacating. The sheet names the previous trade's completion gate (e.g. "concrete cured to 24 MPa, base plates installed, HDB tested") and the next trade's start gate. If the gates aren't named, the variation lands the day the trade arrives and can't start.

2. Cranage and lift coordination. Most inner-Auckland sites need a mobile crane or HIAB for steel, roof framing, and exterior cladding. The crane is on site for half a day. The sheet for each trade that needs the crane names: the date, the duration, the trade owning the crane that day, and the cost-sharing. If those four lines are missing, the variation lands at the bill.

3. Working hours and noise constraints. Inner-Auckland residential alteration work is usually under a Resource Consent condition limiting working hours (often 7am-6pm weekdays, 8am-1pm Saturdays, no Sunday). The sheet records this on the cover, and every trade signs to it. A roofer arriving at 6:30am or running compressors at 6pm is the call that comes from the neighbours, then from the council, then onto the Master Builder's licence.

The Trueworks Per-Project pack is NZ$8,000–12,000 for the full estimation, risk register, contingencies table and pre-trade-start sheets across all major trades on a build. Builders typically save NZ$10,000–20,000 of their own time per job.

The 8-12 trade queries that turn a meeting from 3 hours into 45 minutes

The body of every Pre-Trade-Start sheet is a list of 8 to 12 specific questions to the subcontractor, written in the second person so they can be cut and pasted into an email. Generic checklists don't work — the questions have to be project-specific.

Examples from a recent town-house build we reviewed:

"Your quote dated 14 January 2026 priced off architectural set Rev C. The construction set is now Rev E. Please confirm in writing that you have read the changes log (Rev C-D dated 27 February, Rev D-E dated 11 April) and that your price is unchanged."
"Your quote includes 'all flashings as per E2/AS1'. The plaster cladding system on the west elevation requires a specific manufacturer-supplied head-flashing detail. Please confirm this is in your scope and named on your shop drawings."
"The crane is on site Wednesday 17 June, 0700-1100, for the roof framing lift. Your scope assumes the crane is available — please confirm you can have your team and material on site for that window, and that any delay to the crane departure is your variation."

Each question is specific, each is answerable in writing, and each closes out a future variation conversation before it starts.

What this does to the meeting and to the Guarantee file

The Pre-Trade-Start sheet is emailed 5 to 10 working days before the meeting. The subcontractor answers each question in writing. The meeting then covers only the items the subcontractor flagged, the open variations, and the sign-off:

| Meeting agenda item | Time | |---|---| | Cover review | 5 min | | Open variation discussion | 15-20 min | | Programme and coordination interfaces | 10 min | | Sign-off | 5-10 min | | Total | 45 min

If a defect lands at year 3 or year 5 and the RMBA Guarantee underwriter requests the file, the Master Builder hands over the Pre-Trade-Start sheet for the relevant trade. It names the codes, the manufacturer specifications, the variations, the sign-off. The underwriter's claim handler reads it once and either accepts the claim is covered or identifies the contractor-side fault. Either way, the Master Builder isn't writing the defence three years after the fact from notes.

What to put on the sheet before the next trade starts

Five items, every time:

Trade name, scope reference (quote number, drawing revision), and code list.
Inclusions and exclusions, lifted from the quote verbatim, with any obvious gaps flagged.
Manufacturer warranty terms for any product-warranted element (roof sheet, joinery, membrane, tanking).
8-12 trade queries specific to this build, this site, this set of drawings.

Sign-off block with date and the contractor's acknowledgment that the answers are binding.

Each Master Builder we work with builds a master template, then customises per trade per job. After 2-3 jobs the template runs itself.

FAQ — NZ Pre-Trade-Start meetings and the Master Build Guarantee

Q1: Is a Pre-Trade-Start sheet a contractual requirement under the Master Build Guarantee? The Guarantee doesn't mandate a specific document — but the underwriting expects the Master Builder to have run the build to a documented standard. A Pre-Trade-Start sheet is the most common evidence of that documented standard on residential work.

Q2: Who attends the Pre-Trade-Start meeting on a typical NZ residential build? The head contractor's site manager, the subcontractor's principal or foreman, and (for trades with engineering or architectural interfaces) the relevant designer. On RMBA jobs the principal contractor's nominated Quality Assurance lead also attends if the trade is structural or weathertightness-critical.

Q3: How far ahead of the trade landing on site should the meeting be held? 5-10 working days before the trade is scheduled to start. Earlier than 10 days, the answers go stale; later than 5 days, there's no time to fix any variation that surfaces.

Q4: What's the most common omission from NZ Pre-Trade-Start sheets we see? The codes and standards table — most builders run a generic checklist that names the trade scope but doesn't tie each scope item to its specific NZS / AS-NZS / Building Code clause. Without the code reference, the file doesn't survive a later defect or Guarantee claim.

Q5: Can a Pre-Trade-Start sheet be used as the basis for the head-contractor's claim against a subcontractor on a defect? Yes. A signed Pre-Trade-Start sheet naming the spec, the codes, and the scope is the head contractor's evidence that the subcontractor was instructed to the correct standard. A defect arising from the subcontractor's departure from that scope becomes a back-charge against the subcontractor's retentions.
