Producer Statements and Inspections During a Build

A producer statement is a signed assurance from a suitably qualified professional that part of the work has been designed or built to meet the NZ Building Code. Most often it comes from a chartered structural engineer, confirming either the design of an element or that the completed work matches what was designed and observed on site.

The important thing to understand is what it is and is not. It is professional advice, backed by the author’s qualifications and indemnity, that the council may choose to rely on when assessing your consent. It is not a legal substitute for the council’s own judgement, and the council can always ask for more. There are different kinds, broadly covering design and construction review, but for a home the ones you are most likely to see relate to structural and geotechnical work, where an engineer takes responsibility for the parts of the build that keep it standing. It sits within the wider consent process, which our guide to the building consent process in Nelson Tasman sets out in full.

The council inspects your build at set hold points named in your building consent, checking the work against the approved plans and the NZ Building Code. The common ones are the foundations, the framing, the pre-line stage just before linings go on, and a final inspection once the home is complete.

The logic behind the timing is simple: each inspection happens while the work can still be seen, before the next stage covers it. Foundations are checked before the concrete is poured, framing before it is wrapped and clad, and pre-line before the walls are lined, so anything that needs correcting is caught while it is cheap and accessible to fix. Your specific consent lists the exact inspections required, because a sloping site, a coastal exposure or an unusual structure can add hold points beyond the usual set. If an inspection does not pass, the build does not proceed past that point until the work is put right and re-inspected. That discipline is one of the quiet strengths of a well-run build: nothing important is covered up without an independent check first.

Three parties carry different responsibilities. The Licensed Building Practitioner records and stands behind the restricted building work, the engineer signs producer statements for the elements they designed or observed, and the council carries out the inspections and issues the final code compliance certificate under the Building Act.

Restricted building work is the structural and weathertightness work that, by law, must be carried out or supervised by a Licensed Building Practitioner, who provides records of the work as part of the file. The engineer’s role is narrower and deeper: they take professional responsibility, through producer statements, for the specific elements within their expertise. The council sits over the whole, inspecting at the hold points and, at the end, deciding whether the completed home meets the consent well enough to certify. The table below sets out who does what.

None of these overlaps entirely, which is exactly the point. Each verifies a different slice of the work, so the assurance is layered rather than resting on any single signature.

They give you independent eyes on the work at the moments that matter most, before anything is covered up, so problems are found while they are still easy and cheap to correct. Because the checks are shared across the engineer, the Licensed Building Practitioner and the council, no single party is quietly marking their own homework.

That independence is the real protection. A producer statement means a professional has staked their name and indemnity on an element being sound. A council inspection means someone with no stake in the build has physically looked at the work against your consent. A practitioner record means the person responsible for the restricted work is named and accountable. For you as the homeowner, this is verification you did not have to arrange yourself, layered through the build rather than left to a single hopeful sign-off at the end. It is worth being clear about what it confirms: these checks assure the work meets the NZ Building Code, which is the legal minimum, not a measure of comfort or energy performance. A genuinely warm, dry, low-running-cost home comes from designing well above that floor, to Passive House principles, and modelling it early. The inspections confirm the build matches the design; the design is where performance is actually decided.

Every passed inspection, signed producer statement and practitioner record becomes part of the file the council reviews before issuing your code compliance certificate, so the paper trail is not administrative clutter but the evidence that lets the build be signed off cleanly. In an open-book build, the cost of that work is visible too, rather than hidden in a lump sum.

This is where the checks and our way of working meet. Ecotectural prices open-book, a promise we call Built in the Open, so consent fees, inspection costs and any engineering or specialist input appear as real lines you can see, with the builder’s margin, a flat 15 percent, agreed openly rather than buried. Our guide to how open-book pricing works shows how those lines are built up. Keeping the inspection and producer-statement records tidy through the build is part of the same discipline, because a complete, well-ordered file is what allows the code compliance certificate to be issued without a scramble for missing paperwork at the end. A build that is honest about its costs tends to be honest about its records, and both leave you in control. You can see how we hold the whole process together on our design and build page.

A producer statement is a professional’s signed assurance that part of the work meets the NZ Building Code, and council inspections are the independent checks at each hold point through the build, from foundations to final. The Licensed Building Practitioner, the engineer and the council each verify a different part, which gives you layered, independent assurance rather than a single unchecked sign-off, and every record builds the file behind your code compliance certificate.

Understanding these checks makes you a calmer client, because you can see how a well-run build is verified as it goes, not hoped over at the end. Ecotectural has built architectural homes across Nelson Tasman since 2006, coordinating the engineer, the Licensed Building Practitioner and the council through every inspection, and pricing the work openly under our Built in the Open promise. If you are planning a build and want to understand how the consenting and inspection process will run for your project, the best first step is to arrange a consultation.
