Quick answer
Kitchen cabinetry itself is rarely a consented item or a producer statement item. It sits inside the wider building consent as fittings, while the services it connects to, plumbing, ventilation, electrical and gas, are what the Building Code and the CCC actually check. The kitchen supplier's real job at CCC time is to hand the main contractor clean as-built and appliance information so the connected trades' records of work line up.
Key points
- A kitchen is fittings inside a consent, not usually a separately consented structure.
- Producer statements (PS1 to PS4) almost never cover cabinetry itself, but the connected trades issue statutory records of work.
- Plumbing (G12, G13), ventilation (G4) and gas or electrical connections are the real compliance touch points.
- Replacing a kitchen like-for-like can be exempt under Schedule 1 of the Building Act 2004; moving services usually is not.
- At CCC time the main contractor needs as-builts, an appliance schedule and confirmed extract ducting from the kitchen supplier.
- MTN packages this handover so the CCC application is not held up waiting on kitchen information.
Where a kitchen sits in the consent and CCC chain
A building consent is issued by a Building Consent Authority, in Auckland that is Auckland Council. It approves a set of drawings and specifications against the New Zealand Building Code. Once the work is built and inspected, the same authority issues a Code Compliance Certificate, the formal statement that the completed work meets the consent. A kitchen almost always lives inside that process as part of a whole-dwelling consent rather than as its own separate application.
For a new build or a townhouse development the kitchen is drawn on the consented plans as fittings and fixtures. The cabinetry, benchtops and splashback are shown, but the elements an inspector signs off are the services behind them. If you are pricing a job from the consent set, the drawings that matter to us are the kitchen elevations and the services layout, which we cover in pricing kitchens from architect and consent drawings.
- Consented and inspected: water supply, waste and drainage points, mechanical extract, electrical and gas connections.
- Shown but not separately certified: cabinet carcasses, doors, drawers, benchtops and handles.
- Checked at final: that installed appliances and extract match the approved drawings and appliance schedule.
When a kitchen needs its own consent, and when it does not
For a new dwelling the question does not arise, the kitchen is inside the whole-of-building consent. The grey area is renovation and replacement in existing homes, where the answer depends entirely on what you touch.
Swapping cabinetry and benchtops in an existing kitchen, with no change to the plumbing layout, structure or fire separations, usually falls under the exempt work in Schedule 1 of the Building Act 2004. The moment you relocate the sink, add a new waste, cut into a structural wall or run a new gas point, consent is generally required. Small developers doing repeat townhouse layouts rarely hit this, since the kitchens are consented with the build, a pattern we describe in kitchens for small developers building 3 to 10 townhouses.
| Kitchen change | Consent usually required? |
|---|---|
| Replace cabinets and benchtop, same layout | No, typically exempt under Schedule 1 |
| Relocate the sink or add a new waste point | Yes, drainage and plumbing work |
| Remove or alter a load-bearing wall | Yes, structural work |
| Add a new gas hob connection | Yes, gasfitting and often consent |
| New rangehood duct through external cladding | Yes, weathertightness penetration |
| New dwelling or townhouse | Covered by the whole-building consent |
Which Building Code clauses touch the kitchen
The kitchen interacts with several Building Code clauses, none of which are about the cabinetry as furniture. They are about the services and the internal environment around it.
| Clause | What it covers for the kitchen |
|---|---|
| G3 Food preparation | Adequate space and surfaces for preparing food |
| G4 Ventilation | Mechanical extract for cooking, usually a ducted rangehood |
| G9 Electricity / G11 Gas | Safe supply to hob, oven and appliances |
| G12 Water supplies | Potable hot and cold water to the sink and dishwasher |
| G13 Foul water | Waste and trap from sink and dishwasher to drainage |
| E3 Internal moisture | Splashback and substrate around the wet zone |
| B2 Durability | Materials lasting their required in-service life |
The clause that most often causes a query at final is G4. An inspector wants cooking extract handled, and in most Auckland residential work that means a rangehood ducted to outside air rather than a recirculating unit, sized to the acceptable solution G4/AS1.
Producer statements, and why the kitchen is rarely one
Producer statements are not defined in the Building Act. They are a widely accepted form of supporting evidence a Building Consent Authority may rely on at its discretion. There are four, and they split into design and construction.
| Statement | Purpose and issuer |
|---|---|
| PS1 Design | Author of a design confirms it meets the Building Code; issued by the design professional and lodged with the consent |
| PS2 Design Review | Independent peer review of that design; issued by a reviewing engineer |
| PS3 Construction | Confirms work was built to the approved design; issued by the contractor or installer |
| PS4 Construction Review | Confirms the built work was reviewed on site; issued by a chartered professional engineer |
Kitchen cabinetry is not normally a producer statement item. Producer statements attach to specifically engineered elements, structure, fire systems, geotechnical work, or a designed mechanical system. A run of cabinets and a benchtop is none of those, so a kitchen manufacturer does not typically issue a PS3 for the joinery. Where a producer statement does appear near a kitchen it is usually for the mechanical ventilation design in an apartment building, issued by the services engineer, not by us.
The records of work that actually count
The statutory paperwork around a kitchen comes from the licensed trades that connect it, not from the joinery. Each has its own regime and its own certificate.
- Plumbing and drainlaying: a Record of Work under the Plumbers, Gasfitters, and Drainlayers Act 2006 for the sink, dishwasher and waste connections.
- Gasfitting: gas certification and a Record of Work under the Gas (Safety and Measurement) Regulations 2010 for a gas hob or cooktop.
- Electrical: a Certificate of Compliance and an Electrical Safety Certificate under the Electricity (Safety) Regulations 2010 for the oven, hob and appliance circuits.
These records feed straight into the CCC application. If a build-to-rent operator has specified a particular appliance package, the electrician and gasfitter certify against exactly what was installed, so the appliance schedule has to be right, a point we cover in build to rent versus build to sell kitchen spec.
We treat the kitchen handover as a document exercise as much as a joinery one. The main contractor should not be chasing us for a model number or a duct detail while the CCC sits waiting, says MTN's project team.
Restricted Building Work and Licensed Building Practitioners
Restricted Building Work is the structural and weathertightness work on a home that must be carried out or supervised by a Licensed Building Practitioner, with a Record of Work provided. Installing kitchen cabinetry is not itself Restricted Building Work.
The intersection is at the edges. Cutting a rangehood duct through external cladding is a weathertightness penetration, so that penetration and its flashing sit within Restricted Building Work and belong to the LBP managing the envelope. Altering a load-bearing wall to open up a kitchen is structural Restricted Building Work. We coordinate our install around those items rather than performing them.
What MTN hands over at CCC time
The purpose of the handover pack is plain, the main contractor's CCC application should not stall waiting on kitchen information. We assemble the kitchen-side documents so the connected trades and the council inspector have what they need.
- As-built confirmation that the installed kitchen matches the consented elevations and services layout.
- An appliance schedule listing make and model of hob, oven, rangehood and dishwasher, with the rangehood duct route and termination.
- Extract confirmation showing the rangehood is ducted to outside air and sized to G4/AS1.
- Splashback and wet-area substrate details behind the sink zone for E3.
- Sealing details at sink and benchtop junctions where waterproofing interfaces with the joinery.
On single-run kitchens this is short, on a large mixed development it can be a schedule per unit type. Either way the format is the same, and we set it up early rather than at handover, which we discuss in single-wall townhouse kitchen design and cost.
The kitchen is a late trade, so its documents sit close to the final inspection.
How kitchen sign-off feeds the inspection timeline
The kitchen is one of the later trades on site, which puts it close to the finish line for the CCC. A missing duct termination or a wrong appliance model can hold the final inspection and, with it, the certificate.
Sequence discipline matters most on repeat townhouse programmes, where a small documentation gap multiplies across every unit. The Auckland Unitary Plan has driven a wave of that density, and the kitchens have to keep pace with the inspection cadence, as we set out in the Auckland Unitary Plan and the townhouse kitchen boom.
Frequently asked questions
Does a kitchen need a building consent on its own?
Not usually. In a new build the kitchen is covered by the whole-dwelling consent. A standalone replacement with no change to plumbing, structure or fire separations is generally exempt under Schedule 1 of the Building Act 2004.
Does the kitchen manufacturer issue a producer statement?
In almost all cases no. Producer statements attach to engineered structure, fire or mechanical systems, not to cabinetry. The compliance paperwork around a kitchen comes from the connected plumbing, gas and electrical trades instead.
What documents does the main contractor need from the kitchen supplier for the CCC?
As-built confirmation against the consented drawings, an appliance schedule with makes and models, extract ducting confirmation for G4, and splashback and wet-area substrate details for E3. MTN packages these together at handover.
Is kitchen installation Restricted Building Work?
Installing cabinetry is not Restricted Building Work. The intersection is at structural alterations and at the rangehood duct penetration through external cladding, which are weathertightness and structural items owned by a Licensed Building Practitioner.
Why does the rangehood matter so much at final inspection?
Building Code clause G4 requires cooking extract to outside air in most Auckland residential work. A recirculating rangehood or a missing duct termination is a frequent reason a final inspection is not signed off.
Who provides the records of work that support the CCC around a kitchen?
The licensed trades do. Plumbers and drainlayers issue records under the Plumbers, Gasfitters, and Drainlayers Act, gasfitters certify gas work, and electricians issue a Certificate of Compliance and Electrical Safety Certificate.
