What a quantity surveyor actually does in NZ
A quantity surveyor (QS) helps homeowners and builders understand the cost of a project before and during the build. In New Zealand, a QS may be involved in:
- Preparing a cost plan or budget - Measuring quantities from plans - Checking tender prices and comparing quotes - Valuing work for progress payments - Assessing variations and final account claims - Helping with insurance or dispute work
A QS usually does **not** carry out the actual building work. That matters because building consents and council permits are generally about the **physical work** on the property, not the act of preparing estimates, reports, or cost advice.
Does quantity surveyor work need a building consent?
In most cases, **no**. Pure professional QS services do not require a building consent because they do not alter the building or land.
Examples of work that usually **does not** need council consent include:
- A pre-build estimate or elemental cost plan - A tender analysis report - A valuation of work completed for a payment claim - A dispute report or expert witness-style cost assessment - A cashflow or budget programme for a renovation
However, if the QS is also arranging or overseeing physical building work, the **building work itself** may need a consent. The need for consent depends on the job, not the title of the person involved.
For example, if a homeowner hires a QS to prepare a remediation budget for a leaky home and the project later includes recladding, structural repairs, or changing a weathertight detail, those building works may need consent even though the QS’s report does not.
When quantity surveyor-related projects may need consent or approval
A council building consent or other permit may be needed where the wider project involves controlled building work. Common examples include:
- **Structural alterations** such as removing load-bearing walls or adding new beams - **Additions and major alterations** to a house, garage, sleepout, or deck - **Weathertightness repairs** that involve opening up external wall systems or changing cladding and flashing details - **Bathroom, kitchen, or laundry upgrades** where plumbing, drainage, ventilation, or structural changes are involved - **Retaining walls** above the consent threshold or supporting additional load - **New drainage or service connections** that require separate approvals from the council or network provider - **Building near site boundaries**, where planning rules, setbacks, or fire separation may apply - **Work on heritage buildings** or properties with special overlays or district plan controls
Other council approvals may also be needed, depending on the site:
- **Resource consent** for land use, earthworks, height-to-boundary issues, or work in a protected area - **Road corridor or driveway permits** for work affecting the footpath, berm, or access - **Encroachment or corridor approvals** if structures project over or near council land - **Harbour, coastal, or regional approvals** for certain earthworks or water-related sites
If you’re not sure, ask the council early. Councils in NZ can interpret plans differently when a property has overlays, flood risk, or historic restrictions.
What work is usually exempt
Some smaller or lower-risk building work may be exempt from building consent under the Building Act, but the exemption must actually apply to the work being done. The fact that a QS is involved does not create an exemption on its own.
Examples of work that may be exempt, depending on the exact scope, include:
- Minor non-structural repairs and maintenance - Some internal lining replacements where nothing structural or moisture-related is changed - Small detached garden structures below the relevant size threshold - Some low-risk decking, fencing, or retaining work below the consent threshold - Cosmetic renovation work that does not affect structure, fire safety, drainage, or weatherproofing
Be careful here: a project that looks simple can still need consent if it affects any of the following:
- Structure - Weathertightness - Sanitation or drainage - Fire safety - Means of escape - Building accessibility
For example, replacing a bathroom vanity may be exempt, but moving plumbing, altering drainage, or changing part of the floor structure may trigger consent or restricted trade work requirements.
Who actually needs the licence or authorisation?
A quantity surveyor does **not** need a building practitioner licence just to do QS work. But the trades doing the physical work may need formal authorisation.
| Type of work | Who regulates it | What to check | |---|---|---| | General building work | Council / Building Act system | Whether a building consent is needed; whether the builder is qualified for the job | | Electrical work | Electrical Workers Registration Board (EWRB) | Electrical worker licence and compliance certificate | | Plumbing, gasfitting, drainlaying | Plumbers, Gasfitters and Drainlayers Board (PGDB) | Restricted work licence and producer statement/certification where required | | Design work for some structures | May need a chartered professional or LBP depending on scope | Whether drawings and calculations are fit for consent |
If your QS is acting as a project manager or helping coordinate contractors, they should still be clear about what is advice and what is actual regulated work.
The consent process, step by step
If your renovation or build needs council approval, the process usually runs like this:
1. **Define the scope early** - Confirm what is being changed, removed, added, or repaired. - Make sure the scope is written down before anyone starts.
2. **Check with the council** - Ask whether the work needs a building consent, resource consent, or both. - For more complex sites, request a pre-application meeting if available.
3. **Get proper plans and documents** - Council will usually want drawings, specifications, and sometimes structural or fire documentation. - A QS may help estimate cost, but the consent application is usually based on design documents rather than pricing information.
4. **Apply and pay fees** - The council assesses the application and may request more information. - Processing times vary, especially in busy periods or when the plans are incomplete.
5. **Wait for approval before starting** - Do not begin consented work until the approval is granted, unless the council has clearly allowed a staged or limited start.
6. **Book inspections during the build** - Councils inspect key stages such as foundations, framing, insulation, drainage, and final sign-off. - Your builder or project manager should organise these visits.
7. **Get code compliance at the end** - When the work is finished and meets the approved plans, the council issues the final sign-off, usually a Code Compliance Certificate (CCC).
If the project includes any specialist trade work, make sure the relevant certificates and records are kept. Missing paperwork can delay the CCC.
How a quantity surveyor helps keep consented projects on track
A good QS can save money and reduce permit-related surprises by helping you:
- Set a realistic budget before you commit to design - Compare quotes on a like-for-like basis - Identify cost risks that may affect design choices - Track variations so the job does not blow out unexpectedly - Keep a clear record of approved scope versus extras - Price contingency for older homes, especially villas, bungalows, and 1970s–1990s houses where hidden defects are common
This is especially useful in New Zealand’s renovation market, where labour shortages, material lead times, and weather delays can all affect costs. In winter, for example, weather-sensitive work may take longer, which can push out labour and site costs.
Risks of skipping consent
Skipping consent can seem faster and cheaper, but it can create serious problems later.
Possible risks include:
- **Council enforcement action** and being required to stop work - **Orders to fix or remove** non-compliant work - **Problems selling the house** because lenders, lawyers, or buyers ask for consent records - **No Code Compliance Certificate**, which can complicate refinancing or sale - **Insurance issues** if damage is linked to unauthorised work - **Higher repair costs** if work has to be opened up and redone - **Safety risks** if structural, drainage, or fire requirements were ignored
A short-term saving can become much more expensive if you need retrospective consent, remedial work, or legal advice later. Retrospective or “after the fact” applications are not guaranteed to succeed and can be harder to prove, especially if parts of the work have already been covered up.
How to protect yourself before hiring a quantity surveyor or builder
To reduce risk, ask these questions before work starts:
- Does the project need building consent, resource consent, or both? - What work is exempt, and what is not? - Who is responsible for lodging the consent application? - Which parts of the job must be done by licensed or registered trades? - Will the builder arrange inspections and CCC sign-off? - What documentation will we receive at the end?
Also ask for:
- A written scope of work - A written fee proposal or quote - Proof of relevant licences or registrations for trade work - Copies of drawings, specifications, and approval documents - A clear list of exclusions and provisional sums
Getting at least two or three written quotes is smart, but don’t choose on price alone. Check whether the scope matches, whether consent costs are included, and whether the quote allows for likely variations.
Bottom line for NZ homeowners
Quantity surveyor services themselves usually do **not** need a building consent. But the renovation, remediation, or construction project they are helping to cost or manage may well need one.
If the job involves structure, drainage, weathertightness, services, or land-use effects, check with the council before work starts. A QS can help you budget and compare costs, but they are not a substitute for consent, licensing, or code compliance.
The safest approach is simple: define the work properly, confirm the approvals needed, use qualified trades, and keep every approval and certificate on file from start to finish.
